List Workflow MCP Tools

Every tool a server publishes, tool-name ordered. The server list reports tool names only, so this is where a caller reads the workflowId that DELETE /api/v2/workflow-mcp-servers/{serverId}/tools/{workflowId} addresses. Returned in one page rather than paged — so nextCursor is always null — and capped at 2,000 tools, which is far above any real server's inventory. A workspace API key is rejected with 403; use a personal API key.

GET/api/v2/workflow-mcp-servers/{serverId}/tools
X-API-Key<token>

Your Sim API key, personal or workspace-scoped. Generate one under Settings, then API Keys. Operations that reject workspace keys say so in their own description.
