Dify Workflow

Expose your Dify workflows as tools, one per API key, with their parameters discovered automatically.

LABSCO SUMMARY

One key, one tool — which is how you expose several workflows at once.

The multi-key option is the useful detail: rather than a single generic "run a workflow" tool where the model has to name the right one, each key registers separately with its own parameters, so the model picks by capability. The trade-off is that keys live in the client config in plain text, and adding a workflow means adding a key and restarting.

What it is

A bridge that turns Dify Workflows into callable tools. It reads each workflow's parameters from Dify at startup rather than requiring you to declare them, so a workflow you change in Dify shows its new inputs after a restart.

What you get

  • Your Dify Workflow available as a tool in the conversation
  • Workflow parameters retrieved and displayed dynamically, not hard-coded in a schema
  • Multiple keys supported: set DIFY_API_KEYS to a comma-separated list and each key becomes its own tool, with a number appended to distinguish them
  • Configuration is environment variables only — no config file to maintain

Requirements

A Dify endpoint in DIFY_BASE_URL and access to the workflow via DIFY_API_KEY, or several in DIFY_API_KEYS. Run with npx @tonlab/dify-mcp-server on Node.js 16 or higher and npm 7 or higher. The npm package is @tonlab/dify-mcp-server, version 1.1.2.

Setup effort

One command plus a key — npx @tonlab/dify-mcp-server, then supply credentials
