AlicenseNot gradedqualityDmaintenanceGovernance engine for MCP tool calls, providing deterministic rule enforcement to block destructive actions like SQL drops, shell commands, and file system modifications before execution.2Apache 2.0Why this server?
Serves a read-only snapshot of a Langflow installation as a knowledge base: look up Langflow components with their exact fields, types, accepted values and defaults; find which components declare a given field name or type; list components by category; and semantically search the docs.langflow.org documentation by meaning. Every answer reports the Langflow/docs version and snapshot date it came from.
