# SplitSI MCP server

This is a Model Context Protocol endpoint (Streamable HTTP, stateless, JSON responses): send JSON-RPC 2.0 messages with POST https://splitsi.io/mcp. GET opens no stream.

## Connect

- **ChatGPT, Claude, Cursor or any OAuth MCP client**: add https://splitsi.io/mcp as a connector; it signs you in with Google.
- **Headless agent**: call the `register_agent` tool without auth (or POST https://splitsi.io/v1/agents), keep the api_key, then send `Authorization: Bearer <api_key>`.
- **No MCP client**: the same 50 tools are REST calls, POST https://splitsi.io/v1/tools/{name}. Catalog: https://splitsi.io/v1/tools, OpenAPI: https://splitsi.io/openapi.json.
