Overview — MCP | XCREENER

XQL's validate/explain/run behavior — the same engine behind the HTTP API — is also available over MCP, through xcreener-mcp: an open-source, local stdio bridge that proxies each tool call to the HTTP API using your account's API key. It also registers an xql_nl_reference tool that fetches the natural-language-to-XQL translation reference.

There's no remote server to point your client at — install the bridge (one click for Claude Desktop, npx for everything else) and it handles the rest.

Connecting

Install the bridge for Claude Desktop, Claude Code, Cursor, Windsurf, or another MCP client.

Tools

The four tools: xql_validate, xql_explain, xql_run, and xql_nl_reference.
