Bernerspace

🚀 Bernerspace

One MCP server for all your integrations, eliminating any hassle.

🚀 Unified MCP server for all OAuth-enabled integrations
One server · One JWT · Many tools

✅ Current Live Integration: Slack — 47 tools tested & available
🔜 Coming Soon: Gmail · Google Calendar · Notion
🎯 Goal: 100+ integrations

🚀 Quick Start

Environment

Create a .env with the following variables:

JWT_SECRET=your-jwt-signing-secret
DATABASE_URL=postgresql://localhost:5432/mcp_server
CLIENT_ID=<slack_client_id>
CLIENT_SECRET=<slack_client_secret>
SLACK_REDIRECT_URI=http://localhost:8000/mcp/slack/oauth/callback

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 .

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

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

✨ Features

Why

Using or integrating MCP servers today is painful because:

• Most MCP servers lack OAuth capabilities, limiting user experience.
• Every MCP server requires separate deployment and management, increasing operational overhead.
• Integration chaos: different authentication layers across MCP servers make unified integration nearly impossible.

What You Get

• Single JWT across services via middleware (HS256, issuer/audience validated).
• OAuth middleware per integration (Slack live; more coming) with DB‑backed token storage.
• Consistent MCP tools interface for each service.
• Unified endpoints you can self‑host, e.g.:
  • http://localhost:8000/mcp/slack
  • http://localhost:8000/mcp/gmail (coming soon)

Current Status

• Current live integration: Slack with 47 fully tested tools available.
  → Learn more about Slack tools: docs/slack/tools.md
• Coming soon: Gmail, Google Calendar, and Notion.

📚 Documentation

All setup instructions, integration guides, and examples are available on our Notion docs:

💻 Usage Examples

LangChain Example

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?"})

🔧 Technical Details

OAuth Flow (Slack)

• GET /mcp/slack returns oauth_url and instructions to authorize the workspace.
• Slack redirects to SLACK_REDIRECT_URI (defaults to /mcp/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.

MCP Client Configuration

Example client entry (mcp.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):

{
  "servers": {
    "slack": {
      "url": "http://localhost:8000/mcp/slack",
      "type": "http",
      "headers": {
        "Authorization": "Bearer JWT"
      }
    }
  },
  "inputs": []
}

Docker

You can run Bernerspace MCP in Docker:

docker build -t bernerspace-mcp .
docker run --env-file .env -p 8000:8000 bernerspace-mcp
