Copy-paste configuration for popular MCP clients.

transport: stdio

Config generated by PluginBench — verify against the source before use.

Environment / auth

NACRE_SERVICE_KEY
required
secret
Service-account key for STDIO mode. The server also needs the deployment's full environment (database and backend configuration) - see docs/mcp.md; the key alone is not enough to start it.
