flow_execution

MCP tool from Langflow MCP by nobrainer-tech

Run flows (run, runadvanced, runsession, webhook, process, predict)

How to use it

Project documentation lists flow_execution for the Langflow MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
