Remote MCP Server (OAuth - Recommended)

This MCP server implements OAuth 2.1 authorization as specified by the Model Context Protocol.

Use our hosted MCP server with any OAuth-compliant MCP client:

{
  "mcpServers": {
    "generect": {
      "url": "https://mcp.generect.com/mcp",
      "type": "http"
    }
  }
}

When you first connect, the client will initiate an OAuth flow:

1. You'll be redirected to the authorization page

2. Enter your Generect API token from beta.generect.com

3. Authorize the client to access your API

4. The client receives an access token and can now use the MCP tools

OAuth Endpoints

Direct API key (no OAuth)

If your MCP client cannot complete the OAuth flow, you can pass the API key directly via the Authorization header. The server accepts any of:

Authorization: YOUR_API_KEY
Authorization: Bearer YOUR_API_KEY
Authorization: Token YOUR_API_KEY
Authorization: Bearer Token YOUR_API_KEY   (legacy)

Example for mcp-remote:

{
  "mcpServers": {
    "generect": {
      "command": "mcp-remote",
      "args": [
        "https://mcp.generect.com/mcp",
        "--header",
        "Authorization: Bearer YOUR_API_KEY"
      ]
    }
  }
}

Local Installation (Alternative)

For local development or when OAuth is not needed:

1. Requirements: Node >= 18

2. Configure environment:

GENERECT_API_BASE=https://api.generect.com
GENERECT_API_KEY=Token <api-key>
GENERECT_TIMEOUT_MS=300000
JWT_SIGNING_KEY=<your-secret-key-for-jwt-signing>
TOKEN_ENCRYPTION_KEY=<32-byte-hex-key-for-token-encryption>

3. Local dev (optional)

npm install
npm run dev:http

4. Build and start (stdio server)

npm run build && npm start

Logging

The server emits one structured JSON log line per event to stderr (stdout is reserved for the MCP stdio protocol). Metadata logging is on by default; set MCP_LOG=0 to disable it entirely.

Privacy — payloads are redacted by default. Request/response payloads can contain personal data of prospects (names, company domains, generated emails). By default these values are not logged verbatim: each is reduced to a non-identifying shape marker (e.g. "first_name": "<str:4>"), so you can see which fields were sent without recording the data itself. Set MCP_LOG_PAYLOADS=1 to log payloads verbatim — intended for short-lived debugging, with the data owner's consent.

Events:

reqId correlates a tool_call with its tool_result. Set MCP_DEBUG=1 for additional verbose output.

The hosted server runs under PM2 (not Docker). View logs on the host with:

pm2 logs generect-mcp                                # live
pm2 logs generect-mcp --err                          # errors only
grep tool_call ~/.pm2/logs/generect-mcp-out.log      # only LLM tool inputs

Tools

• search_leads: Search for leads by ICP filters (supports timeout_ms)

• search_companies: Search for companies by ICP filters (supports timeout_ms)

• generate_email: Generate email by first/last name and domain (supports timeout_ms)

• get_lead_by_url: Get LinkedIn lead by profile URL (supports timeout_ms)

• health: Quick health check against the API (optional url, supports timeout_ms)

Cursor integration (settings.json excerpt)

{
  "mcpServers": {
    "generect-liveapi": {
      "command": "node",
      "args": ["./node_modules/tsx/dist/cli.mjs", "src/server.ts"],
      "env": {
        "GENERECT_API_BASE": "https://api.generect.com",
        "GENERECT_API_KEY": "Token YOUR_API_KEY",
        "GENERECT_TIMEOUT_MS": "300000"
      }
    }
  }
}

Claude Desktop (MCP) setup

Add to ~/.claude/claude_desktop_config.json (or via UI → MCP Servers). Recommended: run via npx so users don't install anything globally.

{
  "mcpServers": {
    "generect-api": {
      "command": "npx",
      "args": ["-y", "generect-ultimate-mcp@latest"],
      "env": {
        "GENERECT_API_BASE": "https://api.generect.com",
        "GENERECT_API_KEY": "Token YOUR_API_KEY",
        "GENERECT_TIMEOUT_MS": "300000",
        "MCP_DEBUG": "0"
      }
    }
  }
}

macOS note: If Claude shows "spawn npx ENOENT" or launches an older Node via nvm, set command to the absolute npx path and/or override PATH:

{
  "command": "/usr/local/bin/npx",
  "env": { "PATH": "/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin" }
}

Alternative without npx:

npm i -g generect-ultimate-mcp

Then use:

{ "command": "/usr/local/bin/generect-mcp", "args": [] }

Deployment (production, PM2)

The hosted server (https://mcp.generect.com) runs under PM2 on the host, fronted by nginx (TLS). The process is defined by ecosystem.config.js:

npm ci && npm run build
pm2 start ecosystem.config.js      # or: pm2 reload ecosystem.config.js
pm2 save                           # persist the process list for reboot
# once, as root, so it survives reboots:
#   pm2 startup systemd -u mcp_user --hp /home/mcp_user

Single instance only. OAuth state (registered clients, auth codes) and MCP sessions are held in memory, so the server must run as one instance. Scaling horizontally requires a shared store (e.g. Redis) first — see ecosystem.config.js.

Required secrets (fail-closed). In production (NODE_ENV=production) the server refuses to start unless JWT_SIGNING_KEY is set to a strong, non-default value; it never falls back to a hardcoded default or an ephemeral key. TOKEN_ENCRYPTION_KEY, if set, must be exactly 64 hex characters (32 bytes).

Docker

Docker is supported for local/alternative runs. Build locally:

docker build -t ghcr.io/generect/generect_mcp:local .

Run the server in a container (note: the same production secrets are required — an insecure default will cause the container to exit at startup):

docker run --rm \
  -e NODE_ENV=production \
  -e GENERECT_API_BASE=https://api.generect.com \
  -e GENERECT_API_KEY="Token YOUR_API_KEY" \
  -e JWT_SIGNING_KEY="a-strong-random-secret" \
  -e TOKEN_ENCRYPTION_KEY="0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef" \
  -e OAUTH_BASE_URL=https://your-domain.com \
  -p 3000:3000 \
  ghcr.io/generect/generect_mcp:local

Remote over SSH (advanced)

Some MCP clients allow spawning the server via SSH, using stdio over the SSH session. Example config:

{
  "mcpServers": {
    "generect-remote": {
      "command": "ssh",
      "args": [
        "user@remote-host",
        "-T",
        "node",
        "/opt/generect_mcp/dist/server.js"
      ],
      "env": {
        "GENERECT_API_BASE": "https://api.generect.com",
        "GENERECT_API_KEY": "Token YOUR_API_KEY",
        "GENERECT_TIMEOUT_MS": "300000"
      }
    }
  }
}

Local testing helpers

• Run a simple health check against the API:

npm run health -- <api-key>

• Call tools via a local MCP client:

npm run mcp:client -- <api-key>

Security Notes

• OAuth tokens are JWTs signed by the server and contain your encrypted API token

• Token encryption uses AES-256-GCM with a key from TOKEN_ENCRYPTION_KEY (or derived from JWT_SIGNING_KEY)

• Fail-closed secrets — in production the server refuses to start with a missing or well-known-default JWT_SIGNING_KEY, and never publishes symmetric key material in the JWKS

• PKCE is required for all authorization code flows (S256 method)

• Dynamic Client Registration allows any MCP client to self-register

• Audience validation ensures tokens are only used with this MCP server

• Log privacy — prospect payloads are redacted from logs by default (MCP_LOG_PAYLOADS=1 to opt in)
