Connect Claude Code to Builder MCP v2

Register the Flowgear Builder MCP endpoint in Claude Code, authenticate, and verify the Builder context before making Workflow changes.

Register and authenticate

  1. Copy the complete hostname of the Flowgear Test Environment.

  2. Verify https://<environment-hostname>/mcp/builder in a browser.

  3. Run:

    claude mcp add --transport http flowgear https://<environment-hostname>/mcp/builder

  4. Run /mcp in Claude Code.

  5. Select Authenticate for flowgear and complete Flowgear sign-in.

Keep the server name flowgear because the sample App repository guidance expects it.

Verify Builder context

Ask Claude Code to:

  1. Read flowgear://builder/guidance once.
  2. Call GetBuilderContext.
  3. Show the Tenant, Site, and Environment without changing anything.

If the Resource was loaded, do not call GetBuilderGuidance as well. Stop if the returned Environment is not the intended Test target.

Review the client's Tool approval settings before starting. Builder discovery is read-only, but save, Debug, and folder Tools can create records or invoke connected systems.

Continue with Build a Workflow with Builder MCP. See Connect Claude Code to tools via MCP for current Claude Code client setup.
