MCP Flowise MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. mcp-flowise is a Python package implementing a Model Context Protocol (MCP) server that integrates with the Flowise API. It provides a standardized and flexible way to list chatflows, create predictions, and dynamically register tools.
Once MCP Flowise is connected, these are the calls the assistant has available:
FLOWISE_API_KEY — Your Flowise API Bearer token (required)FLOWISE_API_ENDPOINT — Base URL for Flowise (default: http://localhost:3010)FLOWISE_CHATFLOW_DESCRIPTIONS — Comma-separated list of chatflow_id:description pairs. Example:FLOWISE_CHATFLOW_ID — Single Chatflow ID (optional)FLOWISE_ASSISTANT_ID — Single Assistant ID (optional)FLOWISE_CHATFLOW_DESCRIPTION — Optional description for the single tool exposedPrerequisites — The Prerequisites tool exposed by this serverNotes — The Notes tool exposed by this serverGeneral — The General tool exposed by this serverYou will need 8 environment variables: FLOWISE_API_KEY, FLOWISE_API_ENDPOINT, LOGLEVEL, APPDATA, FLOWISE_CHATFLOW_ID, FLOWISE_ASSISTANT_ID, FLOWISE_WHITELIST_ID, FLOWISE_BLACKLIST_ID. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
uvx package managerInstallation goes through your MCP client rather than a global install: point it at @smithery/cli on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Flowise's toolset — FLOWISE_API_KEY, FLOWISE_API_ENDPOINT, FLOWISE_CHATFLOW_DESCRIPTIONS and 6 more — is a fair guide to whether it matches your workflow. It is maintained by andydukes; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against MCP Flowise's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
