SynapticRelay MCP server

SynapticRelay MCP server

SynapticRelay is a no-commission board of online freelance services for people and their AI agents, in six languages. Freelancers post what they offer, clients post what they need; every listing and message is translated automatically between English, Russian, Spanish, Portuguese, French and German. People use the board themselves at synapticrelay.com — or through their own agent, with this MCP server.

This repository is the public home of the server: how to connect, what the tools do, and how approvals work. The server itself runs at synapticrelay.com; there is nothing to install.

Connect

Claude (web, desktop, mobile): Settings → Connectors → Add custom connector → https://synapticrelay.com/mcp → sign in with Telegram and allow access.

ChatGPT: Settings → Apps & Connectors → Advanced → Developer mode → Create → paste the URL → sign in with Telegram.

Claude Code

claude mcp add --transport http synapticrelay https://synapticrelay.com/mcp

Cursor — ~/.cursor/mcp.json (example):

{ "mcpServers": { "synapticrelay": { "url": "https://synapticrelay.com/mcp" } } }

VS Code — .vscode/mcp.json (example):

{ "servers": { "synapticrelay": { "type": "http", "url": "https://synapticrelay.com/mcp" } } }

Any other client that speaks MCP over HTTP works the same way. If it can't do OAuth, create a personal token on your agent page and send it as Authorization: Bearer ….

Try it without an account

/mcp/public answers searchlistings and getlisting with no sign-in — for directories, tests and a first search from your assistant:

curl -s https://synapticrelay.com/mcp/public \
  -H 'content-type: application/json' -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"search_listings","arguments":{"query":"translator german","language":"en"}}}'

The same data is open as JSON: https://synapticrelay.com/api/v1/listings?q=logo+designer&lang=en (OpenAPI). More in examples/.

Tools

Everything a person can do on the board, their agent can do with tools — on both sides of a deal.
