Environment Create a `.env` (see `.env.example`) with the following variables: ```bash # Database DATABASE_URL=postgresql://localhost:5432/mcp_server # Auth (choose one) # Option A: HS256 JWT_SECRET=your-jwt-signing-secret # Option B: RS256 via JWKS # JWT_JWKS_URL=https://your-auth-domain/.well-known/jwks.json # JWT_ISSUER=https://your-auth-domain/ # JWT_AUDIENCE=my-api # Slack OAuth SLACK_CLIENT_ID=<slack_client_id> SLACK_CLIENT_SECRET=<slack_client_secret> SLACK_REDIRECT_URI=http://localhost:8000/slack/oauth/callback # Optional: encrypt tokens at rest (comma-separated MultiFernet keys) # TOKEN_ENCRYPTION_KEYS= ``` 1. Install dependencies (choose one) - Using pip - python3 -m venv .venv && source .venv/bin/activate - pip install -e . - Using uv - uv venv && source .venv/bin/activate - uv pip install -e . 1. Run the server - Using Python - python server.py - Server will listen on <http://localhost:8000> - Using Docker - docker build -t bernerspace-mcp . - docker run --env-file .env -p 8000:8000 bernerspace-mcp - Server will listen on <http://localhost:8000> - Using Docker Compose - docker compose up -d 1. Create a JWT to call the MCP server - python generate_jwt.py --user-id <your_user_id> - Use the printed token as: Authorization: Bearer TOKEN ## OAuth Flow (Slack) - GET /slack returns `oauth_url` and instructions to authorize the workspace. - Slack redirects to `SLACK_REDIRECT_URI` (defaults to `/slack/oauth/callback`). - The server exchanges the code, enriches the token details, and persists it in Postgres. - Tokens are stored in table `oauth_tokens` with composite key `(client_id, integration_type)` where `client_id` = your JWT subject (`sub`). ## Database - Schema managed with Alembic (migrations included). - Table: `oauth_tokens(client_id, integration_type, token_json, stored_at)`. - Configure Postgres via `DATABASE_URL`. - Tokens can be encrypted at rest when `TOKEN_ENCRYPTION_KEYS` is set. ## MCP Client Configuration Example client entry (mcp.json): ```json { "servers": { "slack": { "url": "http://localhost:8000/mcp/slack", "type": "http", "headers": { "Authorization": "Bearer YOUR_JWT" } } } } ``` If the user hasn’t completed OAuth, tool calls will return an object with `requires_auth: true` and an `oauth_url` you can open to complete authorization. ## VS Code MCP Client Setup Use this `mcp.json` in your VS Code user settings (replace `JWT` with your generated token): ```json { "servers": { "slack": { "url": "http://localhost:8000/mcp/slack", "type": "http", "headers": { "Authorization": "Bearer JWT" } } }, "inputs": [] } ``` ## LangChain Example ```python from langchain_mcp_adapters.client import MultiServerMCPClient from langgraph.prebuilt import create_react_agent client = MultiServerMCPClient( { "slack": { "transport": "streamable_http", "url": "http://localhost:8000/mcp/slack", "headers": { "Authorization": "Bearer YOUR_TOKEN" }, } } ) tools = await client.get_tools() agent = create_react_agent("openai:gpt-4.1", tools) response = await agent.ainvoke({"messages": "Can you send hello message to my #general groups?"}) ``` ## Docker You can run Bernerspace MCP in Docker: ```bash docker build -t bernerspace-mcp . docker run --env-file .env -p 8000:8000 bernerspace-mcp ``` ## 🚀 Roadmap We’re just getting started. Our goal is to support **100+ integrations** so you can connect any third-party service to your MCP server with ease. ### Coming Soon - 📧 Gmail - 📅 Google Calendar - 📂 Google Drive - 🗂️ Notion - 💻 GitHub - 💬 Discord - 📊 Airtable - 🔍 ElasticSearch - 📝 Confluence …and dozens more on the way. ## 🤝 Contributing We welcome contributions of all kinds — whether it’s fixing a bug, suggesting a feature, improving documentation, or just sharing feedback. ### Ways to Contribute - ⭐ **Star the repo** to show your support and help others discover Bernerspace. - 🐛 [Report a bug](https://github.com/bernerspace/bernerspace/issues/new/choose) so we can fix it quickly. - 💡 [Request a feature](https://github.com/bernerspace/bernerspace/issues/new/choose) or suggest an improvement. - 🛠️ Submit a Pull Request with code changes, docs updates, or tests. ### Stay in Touch - 📧 Email me at [ranga.sumit1999@gmail.com](mailto:ranga.sumit1999@gmail.com) - 🐦 Follow & DM on Twitter (X): [@SumitSandbox](https://x.com/SumitSandbox) Whether you’re a first-time contributor or an experienced developer, we’d love to hear from you and collaborate! ## License This project is licensed under the [MIT License](LICENSE).
