Agent-first skill marketplace — search, evaluate, and install skills across 7 AI platforms via MCP. Features Supply Loop where agents become contributors.

Testplane MCP

A server for Testplane that enables LLMs to interact with web applications.

Universal Infinite Loop MCP Server

A goal-agnostic parallel orchestration framework implementing Infinite Agentic Loop patterns as a Model Context Protocol (MCP) server.

AiList MCP Server

Search and discover Ai projects from Claude Code. Browse 1,400+ MCP servers, tools, and agents. Submit projects via your Ai agent.

ToolRank

Score and optimize MCP tool definitions for AI agent discovery. Analyzes Findability, Clarity, Precision, and Efficiency.

Compute MCP

An MCP server for evaluating arithmetic expressions using a Pratt parser in Rust.

Tidymodels MCP Server

An MCP server for accessing tidymodels GitHub information and generating code.

Pincushion

Stakeholders pin feedback on your live app; your AI coding agent reads it via MCP and fixes it

AgentSeal

Every agent action is recorded in a SHA-256 hash chain; with this, you can actually prove to clients that your agent did what it said it did

llmprobe

Probe LLM API endpoints and report health metrics including time to first token, latency, and throughput. Check single models or run full config-based health checks.

KanseiLink

MCP intelligence layer with 156 services, trust scores from real agent usage, 120 workflow recipes, intent-based discovery, and Agent Voice feedback. Global + Japanese SaaS.

A2ABench

Agent-native developer Q&A API with MCP + A2A endpoints for citations, job pickup, and answer submission.

AI Agent Timeline MCP Server

A timeline tool for AI agents to post their thoughts and progress while working.

Underground Cultural District MCP Server

23 free and paid tools for AI agents — UUID, JSON, Base64, hashing, JWT, regex plus 218+ digital goods from 22 shops at substratesymposium.com

Semantic-Sift

A reasoning-first MCP middleware that uses heuristics and Neural BERT models to distil context and eliminate noise

swarm.at

Settlement protocol that validates agent actions before execution. Guards destructive operations with hash-chained ledger receipts, trust tiers, and 31 workflow blueprints.

Praison AI

AI Agents framework with 64+ built-in MCP tools for search, memory, workflows, code execution, and file operations. Install via `uvx praisonai-mcp`

UCN Universal Code Navigator

Universal Code Navigator - a lightweight MCP server that gives AI agents call-graph-level understanding of code. Instead of reading entire files, agents ask structural questions like: "who calls this function", "what breaks if I change it", "what's unused", and get precise, AST-verified answers. UCN parses JS/TS, Python, Go, Rust, Java, and HTML inline scripts with tree-sitter, then exposes 28 navigation commands as a CLI tool, MCP server, or agent skill.

Tether MCP

Prevents AI coding agents from drifting off your architecture — blocks wrong dependencies, enforces file structure, and gives agents persistent memory of your project's rules.
