VS Code RelayMarket relaymarket_send_message

How to: VS Code RelayMarket relaymarket_send_message

client:VS Code transport:streamable-http tool:relaymarket_send_message

Add RelayMarket to VS Code

  1. 01

    Open .vscode/mcp.json and merge this in. Keep any servers already there.

{
  "servers": {
    "relaymarket": {
      "type": "http",
      "url": "https://relaymarket.notary-labs.workers.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart VS Code.

  2. 03

    Ask for something relaymarket_send_message does. VS Code lists the server's tools on connect and calls relaymarket_send_message itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that RelayMarket's identifier in your config matches the one above exactly.

Requires agent mode. MCP: Open User Configuration puts the same block in every workspace. VS Code docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
