Remote MCP transport

The Model Context Protocol endpoint for AI assistants (Claude, ChatGPT, etc.) connecting to your Acquainto account. Speaks MCP’s Streamable HTTP transport in stateless mode: send a JSON-RPC 2.0 request per call, get a JSON-RPC 2.0 response back. Most integrators will never call this directly — point your MCP client at this URL, authenticated with an OAuth access token from POST /api/v1/oauth/token or an acq_ API key, and it handles the protocol.

Example request

curl https://api.acquainto.com/v1/mcp \
  -H "Authorization: Bearer acq_live_xxxxxxxx" \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{}'
