Seventeen of the 42 tools do nothing but look: read the flow structure, read a code step untruncated, resolve a dropdown's real option IDs, validate a step configuration and return field-level errors without touching anything. That is the difference between an agent that writes plausible automation and one that writes automation that publishes. The cost is a setup step — the URL is per-account, so there is nothing to paste until you copy it out of your own settings.
Activepieces' built-in MCP server, reached at a Server URL you copy from your own instance's settings. There is no shared address: cloud and self-hosted both give you a per-account URL.
- Discovery tools that read flows, step trees, code steps and run results before changing anything
- Piece research — look up available pieces, their action schemas and dropdown options, including dependent chains
- Flow building: create, duplicate, rename, enable, delete, and build a whole flow in one call
- Validation before publishing — structural checks and field-level step validation that modify nothing
- Tables and runs: query records, list recent runs, read step-by-step outputs and errors
