Workflows, Files, Knowledge. That is what Claude Code sees; each with a name, description, and input schema.

Workflow toolsEvery deployed workflow you publish becomes a tool with its name, description, and input schema.
FilesList, read, write, and append organization Files.
KnowledgeList your Knowledge bases and run retrieval over them.

The 179-integration catalog is not published directly: Claude Code calls one tool, the workflow does the cross-tool work. Browse the integrations

Workflows teams expose first. Build one from a sentence, deploy it, and it becomes a tool Claude Code can call.

ModuleX MCP and Claude Code.

  • Not directly. ModuleX MCP publishes your deployed workflows, Files, and Knowledge as tools, not the third-party integration catalog. The workflows themselves are what act across the tools your organization has connected.

Claude Code asks. Your workflows answer.
