Form.io API Skills

Single entry point for the full Form.io REST API surface. Detailed endpoint references live under ./references/ — one file per capability group.

Preflight — the Form.io MCP server

Check this when you reach your first Form.io tool call, not when this skill activates. The check is whether form_list is callable by you, under whatever name this client exposes it. If it is, proceed. If it is not, load the formio-mcp-setup skill and use it to help the user connect the server; that skill is the only remedy you offer, and this skill writes no MCP configuration itself.

A missing server blocks that call, not the turn. Reading this skill, answering a question from it, planning, and writing files to the working directory all need no server. Do everything that needs no server first and in full, then raise the gap when you actually reach the call that needs it. Opening with a blocked-on-setup message — or asking for a Project URL before there is anything to write to it — spends the user's turn on a step that was not due.

Never work around missing tools

Do not work around missing tools by making direct HTTP requests against a Form.io deployment, and do not write a throwaway script that makes them for you. This library documents the whole Form.io REST surface, which makes hand-rolling requests tempting and wrong — it bypasses the guardrails the tools enforce and can write to a live deployment unreviewed. Stop and report what is blocking instead.

That ban is on build-time work — the configuring you do in this session. It says nothing about the application you are building: an app is expected to call the Form.io REST API at runtime, to log its users in and to read and write their submissions, and formio-api's runtime-scope references document those endpoints for exactly that code.

Which project the tools target

Available tools are not a configured project. Every Form.io tool resolves which project it targets per working directory, so pass cwd — the user's current working directory — on every Form.io tool call; omitting it resolves against the MCP server's own directory, which is fixed at spawn and may be mapped to a different project. Before the first call that reads from or writes to a deployment, ask the server what this directory resolves to by calling the project_get tool with cwd set to the user's current working directory. Do not shell out for this: the connected server answers it directly, with the same resolver every other tool uses, so what it reports is what the next call targets. If project_get is not callable, the connected server predates it — load the formio-mcp-setup skill, which moves the pinned version forward.
