2. Using MCP Servers with Other Clients

Add to your MCP client config (e.g., claude_desktop_config.json):

{
    "mcpServers": {
        "code_assistant": {
            "command": "/path/to/mcp-platform/.venv/bin/python",
            "args": ["/path/to/mcp-platform/servers/code_assistant/server.py"]
        }
    }
}

Windows paths: "command": "C:\\path\\to\\mcp-platform\\.venv\\Scripts\\python.exe"

Available servers:

• code_assistant - AI-powered code analysis, generation, and refactoring (12 tools)
• code_review - Code review, search, and bug fixing (3 tools)
• code_runner - Python/bash execution sandbox (4 tools)
• discord - Discord channel notifications via webhook (2 tools) ⚠️ Requires DISCORD_WEBHOOK_URL
• github - GitHub repo clone, browse, and cleanup (4 tools) ⚠️ Requires GITHUB_TOKEN for private repos
• google - Gmail + Google Calendar (13 tools) ⚠️ Requires Google setup (Apps Script or OAuth — see Google Setup)
• image - Image search, analysis, and AI generation (6 tools) ⚠️ Requires SERPER_API_KEY for search; generation is free
• location - Weather, time, location (3 tools) — uses Open-Meteo (free, no key); falls back to OpenWeatherMap if OPENWEATHER_API_KEY is set
• plex - Media library + ML recommendations (18 tools) ⚠️ Requires PLEX_URL, PLEX_TOKEN
• rag - Vector search and management (8 tools) ⚠️ Requires Ollama + bge-large
• system - System info and processes (3 tools)
• text - Text processing and web search (8 tools)
• trilium - Trilium notes integration (11 tools) ⚠️ Requires TRILIUM_URL, TRILIUM_TOKEN

4. Adding Custom Tools

Step 1: Create the server file

mkdir servers/my_tool && touch servers/my_tool/server.py

Step 2: Implement with @tool_meta

from mcp.server.fastmcp import FastMCP
from tools.tool_control import check_tool_enabled
from client.tool_meta import tool_meta

mcp = FastMCP("my-tool-server")

@mcp.tool()
@check_tool_enabled(category="my_tool")
@tool_meta(
    tags=["read", "search"],
    triggers=["my keyword", "my phrase"],
    template='use my_function: arg1=""',
)
def my_function(arg1: str) -> str:
    """Short description."""
    return json.dumps({"content": f"Processed {arg1}"})

if __name__ == "__main__":
    mcp.run(transport="stdio")

Restart the client and the tool is live — routed, badged, and registered automatically.

Tag vocabulary

Adding External MCP Servers

Create external_servers.json in the project root:

{
    "external_servers": {
        "deepwiki": {
            "transport": "sse",
            "url": "https://mcp.deepwiki.com/mcp",
            "enabled": true
        }
    }
}

Supported transports: sse, http, stdio. Header auth env var convention:

ES_SERVERNAME_TOKEN=your_token_here

5. Distributed Mode (A2A Protocol)

python a2a_server.py    # Terminal 1 — starts on http://localhost:8010
python client.py        # Terminal 2

A2A_ENDPOINTS=http://localhost:8010,http://gpu-server:8020
A2A_EXPOSED_TOOLS=plex,location,text   # empty = expose all

All configured endpoints are discovered and registered concurrently at startup via asyncio.gather() — connection timeouts for unreachable endpoints no longer block each other.

6. Testing

Running Tests

Activate your virtualenv first, then run from the project root:

source .venv/bin/activate        # Linux/macOS
.venv\Scripts\activate           # Windows PowerShell
# WSL2: source /home/$USER/.virtualenvs/mcp_platform/bin/activate

python -m pytest                 # all tests
python -m pytest -m unit         # fast unit tests only
python -m pytest -m integration  # integration tests
python -m pytest -m e2e          # end-to-end tests
python -m pytest --no-cov        # skip coverage (faster)
python -m pytest -x              # stop on first failure
python -m pytest -k "session"    # filter by name

Total: 95 tools across 13 servers

Concurrency & Parallelism

The platform uses asyncio.gather() at several layers to run non-LLM work concurrently:

Hardware note: LLM inference serialises at the Ollama GPU layer regardless of concurrency — one inference runs at a time on a single GPU. The parallelism benefit is in I/O-bound work: HTTP tool calls, database queries, and network requests. True parallel LLM execution would require multiple GPUs or cloud-hosted sub-agents.

8. RAG & Conversation Memory

How context works

Every LLM call receives context assembled in this exact order:

System prompt
  ├─ Persistent memory — top 5 by importance (always injected)
  ├─ Persistent memory — query-relevant (vector search, above threshold)
  └─ Original system instructions + session ID

Conversation RAG — turns that scrolled out of the window (if relevant)

Message window — last LLM_MESSAGE_WINDOW turns (always injected)

Current user message

Lookup chain — what happens on every query:

1. Persistent memory (always) — top 5 highest-importance memories are injected unconditionally into the system prompt, regardless of query relevance. This ensures core facts (your name, family, preferences) are never lost even when no query scores well. Additional query-relevant memories are added on top via vector search.

2. Message window (always) — the last LLM_MESSAGE_WINDOW turns of the current session are included directly as conversation history.

3. Conversation RAG (always) — a semantic search runs against turns that have scrolled out of the window. Results above the reranker threshold are injected between the system prompt and history.

4. LLM generates response using all of the above.

When does each layer save you:

Conversation window (LLM_MESSAGE_WINDOW)

Controls how many recent turns the LLM sees directly. Set in .env:

LLM_MESSAGE_WINDOW=15   # default: 6, recommended: 15

A window of 6 is too tight for normal conversation — information shared early in a session scrolls out before you can ask about it. 15 covers a full back-and-forth without hitting token limits on qwen2.5:14b. If you share something and the LLM seems to forget it a few messages later, increase this value.

Overflow ingestion

When history exceeds the window, older turns are automatically ingested into the RAG vector database as Human + Assistant pairs. They remain searchable via semantic similarity even after scrolling out of the window.

Auto-RAG retrieval

On every message, a semantic search runs against the full RAG store using the current user message as the query. Matching chunks (from old conversation turns, ingested documents, Plex subtitles, or research) are injected into context automatically — no explicit search rag trigger needed.

What each retrieval method is good for

session_history_tool

Added to the rag server. Queries the session SQLite database directly for ordered, timestamped message history. The current session ID is always injected into the system prompt so the LLM can pass it through automatically.

use session_history_tool: session_id="<id>" [limit="20"] [order="asc"]

Triggers: first prompt, what did I ask, earlier in this session, summarise this session, session history

9. Persistent Memory & Proactive Agents

How memory and context work together

The platform has three layers of context, each serving a different purpose:

What this means in practice: If you tell the platform your son's name and ask about it 3 messages later, the message window handles it. If you ask 20 messages later, RAG handles it (usually). If you start a new session tomorrow, only persistent memory has it.

The memory workflow

Step 1 — Have a conversation. Tell the platform things you want it to remember: your name, your family, your projects, your preferences. The more declarative the better ("My wife's name is Suzy" vs "what's my wife's name?").

Step 2 — Memory extracts automatically. After 15 minutes of inactivity, the InactivityWatcher fires and runs the LLM over your session transcript. It extracts facts and stores them in data/memory.db with vector embeddings.

Re-consolidation is smart: it tracks message count at last consolidation and only re-runs if new messages have been added since. Going idle overnight triggers one extraction, not dozens.

Step 3 — Memories inject on every query. On each new message, two things happen: the top 5 highest-importance memories are always injected into the system prompt unconditionally (so your name, family, and key preferences are never forgotten), then a vector search finds additional query-relevant memories and adds them on top. The combined block looks like this:

## Persistent Memory (from past sessions)

The following facts are KNOWN and TRUE. Use them to answer directly.

◆ The user's name is Bob
○ Bob's wife is Suzy, a nurse and excellent cook
○ Bob's son Sam is 11, plays accordion, excels at hockey
...

Step 4 — Memories accumulate over time. Episodic memories accessed 3+ times are promoted to semantic (permanent) tier nightly. The platform gets more useful the longer you use it.

When memory doesn't fire automatically

The inactivity watcher fires 15 minutes after your last message. If you need memories extracted immediately:

:memory consolidate <session_id>

Use :sessions to find the session ID. The command clears the consolidation flag and re-runs extraction regardless of message count.

Memory commands

:memory                        — list all memories (sorted by relevance)
:memory semantic               — permanent memories only
:memory episodic               — session-derived memories
:memory forget <id>            — delete one memory by ID
:memory clear                  — delete all episodic memories
:memory clear session <id>     — delete memories from one session
:memory consolidate <id>       — extract memories from a session now
:memory add <fact>             — manually add a permanent memory
:memory dedup                  — remove duplicate memories

Manually added memories (:memory add) are stored as semantic tier with importance 1.0 — they always rank first in retrieval.

If the LLM forgets something mid-session

Increase LLM_MESSAGE_WINDOW in .env. The default of 6 is too tight — 15 is recommended. Information shared early in a session scrolls out of the window before you can ask about it.

Once a turn scrolls out of the window it moves into Conversation RAG — it's still there, but now retrieved by semantic similarity rather than direct context. This means the query phrasing needs to be close enough to the original content for the reranker to surface it. If the LLM still can't find something that was said earlier in the same session, try rephrasing the question to use the same keywords as the original statement.

For example: if you said "My son Sam plays accordion" and later ask "What instrument does my son play?", the semantic match is strong. But "How about Sam?" is too vague for RAG to confidently return the accordion fact — be specific.

Two memory tiers

Promotion threshold is configurable: MEMORY_PROMOTE_THRESHOLD=3 in .env.

Deleting a session does not delete its memories. RAG chunks are purged, but extracted facts remain. To remove memories from a specific session before deleting it:

:memory clear session <id>

Reading :memory output

PERSISTENT MEMORY
────────────────────────────────────────────────
[11] The user's name is Bob
    ◆ semantic  |  importance: 1.0  |  accessed 163x
[22] Bob's wife Suzy is a nurse and an excellent cook.
    ○ episodic  |  importance: 0.9  |  accessed 89x

Each entry shows:

• [id] — the memory ID, used with :memory forget <id> to delete it
• Content — the extracted fact, written in plain English
• ◆ semantic / ○ episodic — tier: semantic (permanent) or episodic (session-derived)
• importance — score assigned by the LLM at extraction time (0.0–1.0). Higher = retrieved first
• accessed Nx — how many times this memory was returned in a retrieval search. High access count drives promotion from episodic → semantic

Memories are sorted by retrieval score (combination of vector similarity and importance), not by ID or creation date. The most relevant memories for your last query appear first.

Duplicate memories can appear when the same session is consolidated multiple times, or when two sessions contain similar facts. They don't cause errors — the LLM sees both — but they waste context space. Clean them up with:

:memory dedup        — removes exact duplicates, keeps highest importance copy
:memory forget <id>  — removes near-duplicates manually (same fact, different wording)

Persistent Memory

The platform remembers facts, preferences, and outcomes across sessions. After a session ends (or after 15 minutes of inactivity), the LLM extracts memorable information from the transcript and stores it in data/memory.db. On every new session, relevant memories are injected into the system prompt automatically — no re-explaining required.

Agentic Automation (Proactive Agent Scheduler)

The platform can act autonomously or semi-autonomously — running tools on a schedule, polling for conditions, and involving the LLM to interpret results before surfacing them to you. This is the foundation for things like daily briefings, email monitoring, and eventually fully autonomous workflows.

Just describe what you want:

show me my daily briefing every day at 6am
check for new emails every 5 minutes and summarize anything urgent
show me a random photo from my gallery every morning with a short commentary
alert me when I have unread emails
run the weather check every morning at 7am and write a friendly summary

The LLM classifies whether your message is a scheduling request, parses the intent into a job definition, and presents it for confirmation before saving anything. Ambiguous requests are clarified with a question rather than guessed.

Three trigger types:

LLM involvement: Every job can have an llm_prompt — an instruction passed to the LLM after the tool runs. Instead of broadcasting the raw tool output, the LLM interprets it first:

• shashin_random_tool + "write a short commentary about this photo including the location and mood"
• gmail_get_unread + "summarize these emails and flag anything that needs a reply"
• get_weather_tool + "write a friendly morning weather summary"

Tool pipelines: Chain multiple tools in sequence using >> in the llm_prompt. Each step's output is automatically passed to the next step — no LLM required:

use get_day_briefing >> use discord_notify
use gmail_get_unread >> use discord_notify
use calendar_get_today >> use discord_notify

When scheduling, just describe what you want:

Every day at 7am, use get_day_briefing then use discord_notify to send me the result
At 8am today, use get_day_briefing then use discord_notify to send me today's schedule

The scheduler parser will automatically produce the >> chain syntax.

Condition expressions have access to rich context from the tool's JSON output:

total_unread > 0       — fires when Gmail has unread emails
len_results > 0        — fires when a results list is non-empty
result > 10            — fires when a numeric value exceeds 10
result_len > 100       — fires when the raw output is non-trivial

Job management commands:

:jobs                    — list all scheduled jobs
:jobs pause <label>      — pause a job without deleting it
:jobs enable <label>     — resume a paused job
:jobs cancel <label>     — delete a job permanently
:jobs info <label>       — full job detail including cron and last run

Files:

• client/memory_consolidator.py — memory extraction, storage, injection, and :memory commands
• client/proactive_agent.py — scheduler, condition triggers, LLM-based intent parser, and :jobs commands

Required dependency:

pip install apscheduler

Data files (created automatically on first run):

data/memory.db      — persistent memory store
data/scheduler.db   — scheduled jobs store (label, tool, cron, llm_prompt, etc.)

Prerequisites

• Python 3.12+
• 16GB+ RAM recommended
• Ollama installed

1. Quick Start

Install Dependencies

cd mcp-platform
python3 -m venv .venv
source .venv/bin/activate       # Linux/macOS
.venv\Scripts\activate          # Windows PowerShell
pip install -r requirements.txt

WSL2 note: creating .venv inside /mnt/c/ fails because NTFS does not support the Unix symlinks that venvs require. Create the venv in the Linux filesystem instead:

Copy

python3 -m venv /home/$USER/.virtualenvs/mcp_platform
source /home/$USER/.virtualenvs/mcp_platform/bin/activate
pip install -r requirements.txt

LLM Backend

curl -fsSL https://ollama.com/install.sh | sh
OLLAMA_HOST=0.0.0.0:11434 ollama serve
ollama pull qwen2.5:14b-instruct-q4_K_M   # primary inference (recommended — any tool-calling model works)
ollama pull qwen2.5:0.5b                  # routing classifier (fast pre-flight intent detection)
ollama pull bge-large                     # RAG document embeddings
ollama pull qwen3-vl:8b-instruct          # vision / image analysis

GGUF alternative: local GGUF files (e.g. from Hugging Face) work too — download the file and run :gguf add <path_to_file> in the prompt. No config editing needed.

sentence-transformers models (memory embeddings + RAG reranker) download automatically on first use — no manual pull needed.

Google Setup

Option A — Google Apps Script (simpler setup)

1. Go to https://script.google.com and create a new project
2. Delete all existing code and paste the contents of PASTE_INTO_GOOGLE_APPS_SCRIPT.js
3. Replace <SECRET_KEY> in the script with a strong random secret (32+ characters). Generate one: python3 -c "import secrets; print(secrets.token_urlsafe(32))" Anyone who knows this key can read your emails and calendar — treat it like a password.
4. Click Deploy > New deployment > Web app
   • Execute as: Me
   • Who has access: Anyone
   • Click Deploy and copy the Web App URL
5. Add to .env:
   Copy

   GOOGLE_APPS_SCRIPT_URL=<Web App URL>?key=<your SECRET_KEY>

On subsequent script edits, use Deploy > Manage deployments and edit the existing deployment — do not create a new one or the URL will change.

Option B — Google OAuth

One-time setup. After completing these steps the server runs headlessly.

1. Go to https://console.cloud.google.com/ and create a project
2. Enable Gmail API and Google Calendar API
3. Create an OAuth Desktop app client and download credentials.json
4. Place at servers/google/credentials.json
5. Publish app to In Production — this is required. Apps left in "Testing" mode have tokens that expire every 7 days, causing invalid_grant errors on scheduled jobs
6. Run: .venv/bin/python auth_google.py
7. Restart: python client.py

If the token expires later: the platform detects it on the next Google tool call and shows a re-authorisation banner in the UI with a link. Click the link, approve access, paste the authorisation code into the chat — no server restart needed. Alternatively, delete servers/google/token.json and re-run step 6.

10. Intent Patterns & Troubleshooting

Intent Patterns

Routing is driven by the LLM classifier and triggers in each tool's @tool_meta decorator — no manual pattern editing required. Triggers support plain strings and r: prefixed regex patterns.

Force a specific tool:

Using shashin_search_tool, find photos of Sam
Using web_image_search_tool, show me a red panda

Conversational bypass: Queries the LLM classifies as conversational (greetings, opinions, creative writing) bypass tool routing entirely — answered from context with no tools bound.

Scheduling detection: The LLM determines whether a message is a scheduling/automation request — no keyword lists. If detected, it's routed to the ScheduleParser rather than the agent.

Troubleshooting

Ollama not reachable / connection refused:

• Use OLLAMA_BASE_URL=http://127.0.0.1:11434 in .env for local access
• For WSL2 + LAN access, start Ollama with OLLAMA_HOST=0.0.0.0:11434 ollama serve
• Add Windows port proxies (elevated PowerShell):
  Copy

  # Get WSL2 IP (use ip addr — hostname -I is not available on all WSL2 distros)
  $wslIp = (wsl -- ip -4 addr show eth0 | Select-String "inet ") -replace '.*inet (\d+\.\d+\.\d+\.\d+).*','$1'
  netsh interface portproxy add v4tov4 listenport=11434 listenaddress=0.0.0.0 connectport=11434 connectaddress=$wslIp
  New-NetFirewallRule -DisplayName "WSL2 Ollama" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 11434

• WSL2 IP changes on reboot — re-run the portproxy commands above after each reboot

Ollama models not appearing:

• If OLLAMA_BASE_URL points to a LAN IP but Ollama is bound to 127.0.0.1 only, the model list will be empty
• Fix: start Ollama with OLLAMA_HOST=0.0.0.0:11434 ollama serve
• Verify: ollama list

Web UI not accessible from LAN:

The platform binds ports 9000 (HTTP), 8765, and 8766 (WebSockets) to 0.0.0.0 inside the process. Whether other devices on your LAN can reach those ports depends on your environment.

Native Linux:

• Should work out of the box — check your firewall allows inbound on those ports:
  Copy

  sudo ufw allow 9000 && sudo ufw allow 8765 && sudo ufw allow 8766

WSL2 on Windows: WSL2 runs on a private virtual network (172.x.x.x) that is not directly routable from your LAN. Windows must forward LAN traffic to WSL2 using netsh portproxy. Run this in an elevated PowerShell each time the WSL2 IP changes (it changes on every reboot):

# 1. Find your current WSL2 IP (hostname -I is not available on all WSL2 distros)
$wslIp = (wsl -- ip -4 addr show eth0 | Select-String "inet ") -replace '.*inet (\d+\.\d+\.\d+\.\d+).*','$1'
Write-Host "WSL2 IP: $wslIp"

# 2. Add port forwarding for each port (both 0.0.0.0 and specific LAN IP — both are needed)
netsh interface portproxy add v4tov4 listenport=9000  listenaddress=0.0.0.0 connectport=9000  connectaddress=$wslIp
netsh interface portproxy add v4tov4 listenport=8765  listenaddress=0.0.0.0 connectport=8765  connectaddress=$wslIp
netsh interface portproxy add v4tov4 listenport=8766  listenaddress=0.0.0.0 connectport=8766  connectaddress=$wslIp
$lanIp = (Get-NetIPAddress -AddressFamily IPv4 | Where-Object { $_.IPAddress -like "192.168.*" } | Select-Object -First 1).IPAddress
netsh interface portproxy add v4tov4 listenport=9000  listenaddress=$lanIp connectport=9000  connectaddress=$wslIp
netsh interface portproxy add v4tov4 listenport=8765  listenaddress=$lanIp connectport=8765  connectaddress=$wslIp
netsh interface portproxy add v4tov4 listenport=8766  listenaddress=$lanIp connectport=8766  connectaddress=$wslIp

# 3. Allow inbound through Windows Firewall (first time only)
New-NetFirewallRule -DisplayName "MCP Platform 9000" -Direction Inbound -Protocol TCP -LocalPort 9000 -Action Allow
New-NetFirewallRule -DisplayName "MCP Platform 8765" -Direction Inbound -Protocol TCP -LocalPort 8765 -Action Allow
New-NetFirewallRule -DisplayName "MCP Platform 8766" -Direction Inbound -Protocol TCP -LocalPort 8766 -Action Allow

# 4. Allow inbound through WSL2 firewall (first time only — run inside WSL2)
# sudo ufw allow 9000 && sudo ufw allow 8765 && sudo ufw allow 8766

Access from LAN devices using your Windows LAN IP (e.g. 192.168.0.x), not the WSL2 IP:

http://192.168.0.x:9000/client/ui/index.html

To find your Windows LAN IP: ipconfig → look for the 192.168.x.x address on your main adapter.

Tip: if it stops working after a reboot, just re-run the netsh interface portproxy add commands — the firewall rules persist but the WSL2 IP will have changed.

Web UI won't load locally:

netstat -an | grep LISTEN   # check ports 8765, 8766, 9000

Web search returning no results / empty responses:

• Ollama's free tier has a weekly usage cap — when hit, the API returns HTTP 200 with an empty body
• The platform automatically falls back to LangSearch when this happens
• Set LANGSEARCH_API_KEY in .env to enable the fallback (free account at https://langsearch.com/dashboard)
• To confirm which provider is being used, check logs for 🔍 Ollama web search vs 🔍 LangSearch web search

Google / OAuth issues:

• Confirm servers/google/token.json exists — if not, re-run auth_google.py
• Confirm Gmail API and Calendar API are enabled in Google Cloud Console
• Confirm OAuth app is published to In Production (Testing mode tokens expire every 7 days)
• invalid_grant at runtime: the re-auth banner will appear in the UI automatically — follow the link, approve, paste the code into chat

RAG not working:

• Ensure Ollama is running: OLLAMA_HOST=0.0.0.0:11434 ollama serve
• Pull bge-large if missing: ollama pull bge-large

Auto-RAG returning irrelevant context:

• Raise min_score threshold in rag_search_tool call inside run_agent
• Check RAG store isn't polluted: use rag_browse_tool
• Remove a source: use rag_delete_source_tool: source="<source>"

session_history_tool not finding messages:

• Confirm the session ID in the system prompt matches the active session
• Check data/sessions.db exists and is writable

Plex tools returning errors:

curl $PLEX_URL/identity?X-Plex-Token=$PLEX_TOKEN

GGUF model won't load:

• Reduce GPU layers: export GGUF_GPU_LAYERS=20
• CPU only: export GGUF_GPU_LAYERS=0

A2A server not connecting:

curl http://localhost:8010/.well-known/agent-card.json

Conversation history not working:

• Switch to a larger model: :model qwen2.5:14b-instruct-q4_K_M
• Avoid qwen2.5:3b / qwen2.5:7b for history-aware tasks

Tools not appearing:

:tools --all        # check if disabled
# check DISABLED_TOOLS in .env
python client.py    # restart
