Stakeholder MCP Server

An MCP (Model Context Protocol) server that exposes stakeholder personas as tools for iterative product feedback. Each stakeholder represents a distinct role with a unique personality, expertise, and concerns.

Cost-sensitive? The server uses a high default token limit so models can reason about requirements and implementation. To control cost, set STAKEHOLDER_MCP_MAX_TOKENS (see Configuration).

Features

• 7 Pre-configured Stakeholders: Tech Lead, Product Manager, UX Designer, Security Engineer, DevOps Engineer, and two End User personas
• Runtime Persona Management: Create, update, and delete stakeholders at runtime
• Multi-Provider LLM Support: Uses OpenRouter for access to 100+ models (GPT-4, Claude, Gemini, Llama, etc.)
• Flexible Consultation: Query stakeholders individually or in groups (parallel or sequential mode)
• Multiple Transports: stdio (default) and HTTP/SSE support

MCP Tools

Default Stakeholders

Setting up with MCP-compatible tools

Claude Desktop

Add to your Claude Desktop MCP config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "stakeholder-mcp": {
      "command": "bun",
      "args": ["run", "/path/to/stakeholder-mcp/src/index.ts"],
      "env": {
        "OPENROUTER_API_KEY": "your-key-here"
      }
    }
  }
}

Cursor

Add the server to your MCP config. User-level: Cursor Settings → MCP → Edit config (or ~/.cursor/mcp.json). Project-level: .cursor/mcp.json in the repo root.

{
  "mcpServers": {
    "stakeholder-mcp": {
      "command": "bun",
      "args": ["run", "/path/to/stakeholder-mcp/src/index.ts"],
      "env": {
        "OPENROUTER_API_KEY": "your-key-here"
      }
    }
  }
}

Replace /path/to/stakeholder-mcp with the actual path to this project.

Codex CLI

Codex CLI (and the Codex VSCode extension) use a shared TOML config at ~/.codex/config.toml. MCP servers run as local subprocesses over STDIO.

1. Create the config directory (if it doesn’t exist):

   Copy

   mkdir -p ~/.codex

2. Add the stakeholder MCP to ~/.codex/config.toml:

   Copy

   [mcp_servers.stakeholder_mcp]
   command = "bun"
   args = ["run", "/path/to/stakeholder-mcp/src/index.ts"]
   env = { "OPENROUTER_API_KEY" = "your-key-here" }

   Replace /path/to/stakeholder-mcp with the actual path to this repo (e.g. /Users/you/repos/stakeholder-mcp). Use an absolute path so it works from any working directory.

3. Restart Codex (CLI session or VSCode extension) so it reloads the config.

Then in Codex you can ask things like: "List the stakeholders and consult the tech lead on using microservices for a simple blog."

Development

# Run with watch mode
bun dev

# Run tests
bun test

# Type check
bun typecheck

# Test client (basic functionality)
bun run examples/test-client.ts

Quick Start

1. Install Dependencies

bun install

2. Configure Environment

cp .env.example .env
# Edit .env and add your OpenRouter API key

Get an OpenRouter API key at: https://openrouter.ai/keys

3. Run the Server

bun start

The server uses stdio transport, which is the standard for MCP clients like Claude Desktop.

Usage Examples

Example Prompts for AI Models

When using the MCP with Claude, Cursor, or another AI assistant, you can prompt the model to use the stakeholder tools. The model will then call the MCP (e.g. list_stakeholders, consult_stakeholder, consult_group) on your behalf.

Full example: language learning app

The examples/full-example-language-app/ directory contains a full run of the MCP in action: an AI agent (in Cursor) acts as a product manager, consults multiple stakeholders (end users, tech lead, UX designer) to refine gamified vocabulary features for a language app, records the conversations, and produces PDRs (Prompt Requirements Documents). Useful to see the end-to-end workflow and the kind of outputs you can get from a single prompt.

Planning a new feature

• "I'm planning to add a dark mode toggle to our app. Consult the relevant stakeholders (UX, product, maybe tech) and summarize their feedback before we lock the design."
• "We're considering moving our auth from email/password to OAuth-only. Get feedback from the security engineer, product manager, and one end-user persona, then give me a recommendation."

Reviewing a design or spec

• "I've drafted a spec for the new checkout flow (see below). Run it by the product manager, UX designer, and the senior end-user persona. Use sequential mode so each can see the previous feedback."
• "Review this API design with the tech lead and DevOps engineer. Ask them about scalability and deployment concerns."

Before implementing

• "Before I implement this feature, list stakeholders whose expertise is relevant to [security / UX / infra], then consult them on [specific question]."
• "I want to ship a beta of our mobile app. Consult the product manager and both end-user personas on what we should include in the first release."

Custom stakeholders

• "We need accessibility input. Create a stakeholder who's an accessibility consultant, then ask them to review our button and form design."

List Stakeholders (tool call)

{
  "tool": "list_stakeholders",
  "arguments": {
    "filter": {
      "expertise": "security"
    }
  }
}

Consult a Stakeholder (tool call)

{
  "tool": "consult_stakeholder",
  "arguments": {
    "id": "tech-lead",
    "prompt": "What do you think about using microservices for a simple blog?",
    "context": {
      "projectDescription": "A personal blog with ~1000 monthly visitors"
    }
  }
}

Stakeholders remember the discussion (session memory)
If your agent asks a question and then a follow-up, the stakeholder does not see the first message unless you pass a session ID. Set context.sessionId to a stable value for the conversation (e.g. a task id or thread id). The server will load prior consultations for that session from the database and inject them into the prompt, so the stakeholder sees the previous Q&A and can answer follow-ups in context. Use the same sessionId for the initial question and all follow-ups with that stakeholder.

Consult Multiple Stakeholders (tool call)

{
  "tool": "consult_group",
  "arguments": {
    "ids": ["tech-lead", "product-manager", "ux-designer"],

        "content": "Users should be able to sign in with email/password or OAuth..."
      }]
    }
  }
}

      "name": "Sam",
      "role": "Accessibility Consultant",
      "personality": {
        "traits": ["detail-oriented", "empathetic", "standards-focused"],
        "communication_style": "educational and supportive"
      },
      "expertise": ["WCAG compliance", "screen readers", "keyboard navigation"],
      "concerns": ["inclusive design", "legal compliance", "user independence"]
    }
  }
}

Configuration

Environment Variables

Controlling token usage (max tokens)

Consultations call the LLM with a default maximum of 8192 tokens per response so stakeholders can give detailed, thoughtful feedback. You can override this in two ways:

1. Environment variable — Set STAKEHOLDER_MCP_MAX_TOKENS to the desired cap (e.g. 2048 or 1024). The value is clamped to 128,000. Example in .env:
   Copy

   STAKEHOLDER_MCP_MAX_TOKENS=2048

2. Per-request — The consult_stakeholder and consult_group tools accept an optional maxTokens argument; when provided, it overrides the default for that call only.

Runtime stakeholders (created via create_stakeholder or overrides from update_stakeholder) are persisted to a JSON file so they survive server restarts. By default the file is data/runtime-stakeholders.json (same directory as DB_PATH). You can override the path when creating the server via runtimeStakeholdersPath in ServerConfig.

Customizing Stakeholders

Edit config/stakeholders.yaml to customize or add stakeholders:

stakeholders:
  - id: "my-stakeholder"
    name: "Custom Name"
    role: "Custom Role"
    model: "openai/gpt-4-turbo"  # Optional: per-stakeholder model
    personality:
      traits: ["trait1", "trait2"]
      communication_style: "description of how they communicate"
    expertise:
      - "area 1"
      - "area 2"
    concerns:
      - "priority 1"
      - "priority 2"

Project-specific configuration

You can use different stakeholder personas per project by pointing the MCP at a project-local config file. That way each repo gets its own set of stakeholders (e.g. domain experts, product roles) when you use the MCP from Cursor or another tool.

Option 1: Convention (no env vars)
If the MCP server is started with the project as the current working directory (typical when using Cursor’s project-level MCP), it will look for a config file in this order:

1. ./.cursor/stakeholders.yaml (project root)
2. ./config/stakeholders.yaml
3. ./stakeholders.yaml

So you can add .cursor/stakeholders.yaml in your project with project-specific personas; that file will be used automatically when the MCP runs in that project.

Option 2: Explicit path via env
Set STAKEHOLDER_MCP_CONFIG_PATH in the MCP’s env to the path of your project’s config file. Relative paths are resolved from the process working directory (usually the project root when using Cursor’s project-level MCP).

Example: project-level Cursor MCP

1. In your project, create .cursor/stakeholders.yaml with the personas for that project (or put stakeholders.yaml in the project root).

2. In the same project, create .cursor/mcp.json so this project uses the stakeholder MCP with that config:

{
  "mcpServers": {
    "stakeholder-mcp": {
      "command": "bun",
      "args": ["run", "/path/to/stakeholder-mcp/src/index.ts"],
      "env": {
        "OPENROUTER_API_KEY": "your-key-here",
        "STAKEHOLDER_MCP_CONFIG_PATH": ".cursor/stakeholders.yaml",
        "STAKEHOLDER_MCP_DB_PATH": ".cursor/data/consultations.db",
        "STAKEHOLDER_MCP_RUNTIME_STORE_PATH": ".cursor/data/runtime-stakeholders.json"
      }
    }
  }
}

Replace /path/to/stakeholder-mcp with the real path to the stakeholder-mcp repo. If you use the convention above, you can omit STAKEHOLDER_MCP_CONFIG_PATH and only set the paths if you want consultation logs and runtime stakeholders stored under .cursor/data/ for this project.

Generating a project config
Copy the format from config/stakeholders.yaml in this repo, or start from a minimal file:

stakeholders:
  - id: "domain-expert"
    name: "Jamie"
    role: "Domain Expert"
    personality:
      traits: ["pragmatic", "user-focused"]
      communication_style: "clear and concise"
    expertise:
      - "your domain"
    concerns:
      - "accuracy"
      - "usability"

Then add or edit entries to match the roles and expertise that matter for the project.
