Connect Cursor to Semlith over MCP

How to connect Cursor to Semlith over MCP, the command or file that adds it, and how to check the connection works.

Every stanza writes ${SEMLITH_BIN} where the binary goes, the path which semlith prints. Set up your agent client explains it and the HTTP form.

Cursor — ~/.cursor/mcp.json everywhere, or .cursor/mcp.json in one repo. Cursor infers the transport from the presence of url and has no type field; one copied from another client confuses it.

Cursor is connection-tested each release: the registration below is exercised and its MCP log is checked for connected=true. Its tool calls are not tested, so a search that returns wrong results there is worth reporting.

~/.cursor/mcp.json

{
  "mcpServers": {
    "semlith": {
      "command": "${SEMLITH_BIN}",
      "args": ["mcp"]
    }
  }
}

Or against a daemon on another machine, over HTTP:

{
  "mcpServers": {
    "semlith": {
      "url": "http://127.0.0.1:7365/mcp",
      "headers": { "Authorization": "Bearer ${SEMLITH_AGENT_KEY}" }
    }
  }
}
