Helix Query MCP

Use the Query MCP server for Cloud data access. Interactive principals use WorkOS OAuth; headless automation may use an explicitly project-scoped service credential. Never ask for an application database key or use a direct gateway URL.

Tools

• helix_execute_read_query: execute exact validated v3 read JSON.
• helix_prepare_write_query: prepare a five-minute one-time confirmation for exact write bytes.
• helix_execute_write_query: consume that confirmation and dispatch once.

Use textual tenant:<id> or dedicated cluster:<id> targets. Resolve names through the read-only Insights MCP when needed; never guess an ambiguous database.
