EVC Team Relay - MCP Server

Give your AI agent read/write access to your Obsidian vault.

Your agent reads your notes, creates new ones, and stays in sync — all through the Team Relay API.

Works with Claude Code, Codex CLI, OpenCode, and any MCP-compatible client.

Quick Start

1. Install

Option A — from PyPI (recommended):

No installation needed — uvx downloads and runs automatically. Skip to step 2.

Option B — from source:

git clone https://github.com/entire-vc/evc-team-relay-mcp.git
cd evc-team-relay-mcp
uv sync   # or: pip install .

2. Configure your AI tool

Add the MCP server to your tool's config. Choose one authentication method:

Agent key (recommended) — create a key in the Obsidian plugin → Team Relay settings → Agent Keys. Supports read and write: list_files, read_file, tr_search, and upsert_file all work with a single key. Quickstart →

Email + password — use a dedicated agent account on your Relay instance.

Environment variables:

| Variable | Required | Description | |----------|----------|-------------| | RELAY_CP_URL | Yes | Control plane base URL | | RELAY_AGENT_KEY | One of | Agent key from plugin settings — read + write (recommended) | | RELAY_EMAIL | One of | Account email (email/password mode) | | RELAY_PASSWORD | One of | Account password (email/password mode) |

Ready-to-copy config templates are also in config/.

3. Use it

Your AI agent now has these tools:

| Tool | Description | |------|-------------| | authenticate | Authenticate with credentials (auto-managed) | | list_shares | List accessible shares (filter by kind, ownership) | | list_files | List files in a folder share | | read_file | Read a file by path from a folder share | | read_document | Not implemented — no backend route in any auth mode, always raises | | upsert_file | Create or update a file by path — agent-key mode only; raises in email/password (JWT) mode | | write_document | Not implemented — no backend route in any auth mode, always raises | | delete_file | Not implemented — no backend route in any auth mode, always raises |

Typical workflow: list_shares -> list_files -> read_file / upsert_file

Authentication is automatic — the server logs in and refreshes tokens internally.

Tool availability matrix

Not every tool works in every auth mode, and one group doesn't work in either mode — these are two unrelated facts, so don't conflate them:

| Group | Tools | Status | |-------|-------|--------| | Agent key, folder shares | list_files, read_file, upsert_file | Working — the only write path in this MCP server | | JWT (email/password) | list_files, tr_search, read_file | Working, read-only by design | | No backend route in either mode | read_document, write_document, delete_file | Always raise ValueError — not an auth restriction |

• Write access is agent-key-only, by sanctioned policy (see TR-05 (#0cdd5328)): upsert_file is the only write tool with a working backend route, and it only writes when an agent key (RELAY_AGENT_KEY / RELAY_AGENT_KEYS) is configured. JWT mode calling upsert_file raises a clear ValueError naming agent-key mode as the fix, instead of a confusing 404.
• read_document, write_document, and delete_file are a separate, independent gap — the control plane has no backend route for them at all, in agent-key mode either. Switching to an agent key will not make them work: doc-share live content is CRDT/WebSocket-only (no REST bridge), and per-file delete has no DELETE route server-side yet. If routes for these are ever added, they'd still follow the agent-key-only write policy above — JWT would stay read-only.

Remote Deployment (HTTP Transport)

For shared or server-side deployments, run as an HTTP server:

# Direct
uv run relay_mcp.py --transport http --port 8888

# Docker (pulls from Docker Hub automatically)
RELAY_CP_URL=https://cp.yourdomain.com \
RELAY_EMAIL=agent@yourdomain.com \
RELAY_PASSWORD=your-password \
docker compose up -d

# Or pull explicitly
docker pull deadalusevc/evc-team-relay-mcp:latest

By default the server binds to 127.0.0.1 (localhost-only) — the endpoint is not reachable over the network even if the host has a public IP. This matches the common case of a single MCP client on the same machine as the server.

Then configure your MCP client to connect via HTTP:

{
  "mcpServers": {
    "evc-relay": {
      "type": "streamable-http",
      "url": "http://127.0.0.1:8888/mcp"
    }
  }
}

Remote access via SSH tunnel (recommended)

If your MCP client runs on a different machine than the server, tunnel to the localhost-bound port instead of exposing it publicly:

# From the client machine, forward local 8888 to the server's localhost:8888
ssh -N -L 8888:127.0.0.1:8888 user@your-server

Then point the client config at http://127.0.0.1:8888/mcp as above — traffic goes through the SSH tunnel, and the server's bind address never needs to change.

Public / reverse-proxy binding (opt-in)

If you genuinely need the server to accept connections from other hosts directly (e.g. it sits behind a reverse proxy that terminates TLS and handles auth), pass --host explicitly:

uv run relay_mcp.py --transport http --port 8888 --host 0.0.0.0

Only do this behind a reverse proxy or firewall — the MCP HTTP endpoint itself has no built-in authentication, so binding it to 0.0.0.0 on an open network exposes every relay tool call to anyone who can reach the port.

Security

The MCP server provides significant security advantages over shell-based integrations:

• No shell execution — all operations are Python function calls via JSON-RPC, eliminating command injection risks
• No CLI arguments — credentials and tokens are never passed as process arguments (invisible in ps output)
• Automatic token management — the server handles login, JWT refresh, and token lifecycle internally; the agent never touches raw tokens
• Typed inputs — all parameters are validated against JSON Schema before execution
• Single persistent process — no per-call shell spawning, no environment leakage between invocations

Note: If you're using the OpenClaw skill (bash scripts), consider migrating to this MCP server for a more secure and maintainable integration.

How It Works

┌─────────────┐      MCP        ┌──────────────┐     REST API     ┌──────────────┐     Yjs CRDT      ┌──────────────┐
│  AI Agent   │ ◄────────────► │  MCP Server  │ ◄─────────────► │  Team Relay  │ ◄──────────────► │   Obsidian   │
│ (any tool)  │  stdio / HTTP  │ (this repo)  │    read/write   │   Server     │    real-time     │    Client    │
└─────────────┘                └──────────────┘                 └──────────────┘      sync         └──────────────┘

The MCP server wraps Team Relay's REST API into standard MCP tools. Team Relay stores documents as Yjs CRDTs and syncs them to Obsidian clients in real-time. Changes made by the agent appear in Obsidian instantly — and vice versa.
