io.form/formio-mcp
Create and manage Form.io forms, resources, actions, roles, and projects from your AI agent.
The current version, v0.13.0, was published to the official MCP registry on 2026-09-09. It is distributed as @formio/mcp on npm, filed under Other by this index, and declares 6 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.
Using io.form/formio-mcp in Claude, Cursor, Gemini CLI, Cline, or Zed?
MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).
Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-09-12).
Contracts can change after screening, with no version bump. The gate pins io.form/formio-mcp’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.

It pins nothing — project_set can redirect a directory whose environment names a different project. Useful for a launch with nowhere to record a project, such as CI or a container (e.g. https://examples.form.io on the hosted cloud; self-hosted it is either https://your-project.your-domain.com or https://your-host/project-name, depending on how that deployment routes projects). Leave it unset and the agent asks for a project and records it per directory.
FORMIO_BASE_URLOptional, and usually unnecessary: the base URL is DERIVED from the project URL — https://api.form.io for a project on a form.io host, the parent path for a project addressed as a sub-directory — and is asked for only when it cannot be derived, which is a path-less project URL on a customer domain. There is no default. Like FORMIO_PROJECT_URL it is the weakest source, behind a committed formio.json and the per-directory mapping.
FORMIO_API_KEYForm.io project API key. Optional — when omitted the server uses a browser-based portal login flow to obtain a JWT.
FORMIO_LOGIN_FORMURL of a custom login form used by the browser-based portal login flow. Defaults to the deployment's portal login form.
FORMIO_FORCE_BROWSERSet to 1 to attempt the browser login even where the server detects it cannot present one (CI, a container, a remote shell with no display). Use it when the login page is reachable from a browser elsewhere.
FORMIO_INSECURE_TLSSet to 1 to skip TLS certificate verification. For local development against self-signed certificates only — never enable in production.
