Open Collective MCP Server

Let your AI assistant manage your Open Collective page — update profiles, publish posts, create projects, configure tiers, and track finances, all through natural language.

This is a Model Context Protocol (MCP) server that connects to the Open Collective GraphQL API v2. It works with any MCP-compatible client: Claude Code, Claude Desktop, Cursor, Windsurf, VS Code Copilot, and others.

Built by Citizen Infra Builders Club.

Example

Once connected, you can ask your AI assistant things like:

"Show me the balance of our collective"

The assistant calls oc-get-balance and returns:

{
  "balance": { "value": 1250.00, "currency": "USD" },
  "totalAmountReceived": { "value": 8400.00, "currency": "USD" },
  "totalAmountSpent": { "value": 7150.00, "currency": "USD" }
}

"Create a project called 'Community Garden' under our collective"

The assistant calls oc-create-project with the name and description, and the project appears on your Open Collective page.

Quick Start

1. Get an Open Collective Personal Token

Go to your Open Collective account Settings → For Developers → Personal Tokens. When creating the token, enable all available scopes — at minimum the account scope is required for write operations (creating projects, editing profiles, publishing updates). Without it, mutations will fail with "not allowed for operations in scope account."

Rate limit: 100 requests/minute with a Personal Token.

2. Deploy your own instance

Each user deploys their own instance with their own Open Collective token — the server operates on behalf of whoever's token is configured. You can host it on any platform that runs Node.js (Railway, Fly.io, Render, a VPS, etc.) or run it locally.

Option A: Railway (remote HTTP)

Set these environment variables:

Variable	Description
OPEN_COLLECTIVE_TOKEN	Your Open Collective Personal Token
API_KEY	Bearer token for MCP client authentication (any random string you choose)
PORT	Set automatically by Railway — do not set manually

Option B: Run locally (stdio)

git clone https://github.com/Citizen-Infra/open-collective-mcp.git
cd open-collective-mcp
npm install && npm run build
OPEN_COLLECTIVE_TOKEN=<your-token> node dist/index.js

For development, use npm run dev to skip the build step (runs with tsx).

3. Connect your MCP client

Claude Code

Remote HTTP (Railway):

claude mcp add --transport http \
  --header "Authorization: Bearer <API_KEY>" \
  -s user open-collective \
  https://<your-railway-domain>/mcp

Local stdio:

claude mcp add -e OPEN_COLLECTIVE_TOKEN=<your-token> \
  -s user open-collective -- node /path/to/open-collective-mcp/dist/index.js

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "open-collective": {
      "command": "node",
      "args": ["/path/to/open-collective-mcp/dist/index.js"],
      "env": {
        "OPEN_COLLECTIVE_TOKEN": "<your-token>"
      }
    }
  }
}

Cursor / Windsurf / Other MCP clients

Use the stdio configuration above — the command is node /path/to/open-collective-mcp/dist/index.js with OPEN_COLLECTIVE_TOKEN as an environment variable. Refer to your client's MCP documentation for the exact config format.

Development

npm install
npm run dev              # stdio mode (local)
PORT=3000 npm run dev    # HTTP mode (local)
npm run build            # compile TypeScript

Architecture

• Runtime: Node.js + TypeScript with @modelcontextprotocol/sdk
• Transport: Dual mode — stdio for local use (no PORT), Streamable HTTP for hosted deployment (PORT set)
• GraphQL: Lightweight fetch wrapper against https://api.opencollective.com/graphql/v2
• Auth: Two layers — Personal-Token header for OC API; Bearer token (API_KEY) for MCP client auth in HTTP mode
• Structure: Two-layer separation — tools/ define MCP schemas and handlers, queries/ hold raw GraphQL strings

Roadmap

• Publish to npm for npx -y open-collective-mcp install
• One-command install via npx add-mcp
• Expense submission and approval tools
• Event management tools
• Webhook support for real-time notifications

Contributing

Contributions are welcome! This project uses TypeScript with strict mode enabled.

git clone https://github.com/Citizen-Infra/open-collective-mcp.git
cd open-collective-mcp
npm install
npm run dev    # runs with tsx, no build step needed

Before submitting a PR, make sure npm run build passes with no errors.
