The Form.io Agentic Coding Toolset

@formio/ai is what brings Form.io into your agentic coding environment. It provides a series of tools that enable any developer to perform a number of complex actions against the Form.io Enterprise Server using their favorite Agentic Coding toolsets (starting with Claude Code). This turns the Form.io Enterprise Server into a Composable Backend for Agentically Coded Applications.

Getting Started

Getting started is easy. First install Claude Code as follows:

1. Install Claude Code
2. Run claude in your Terminal.
3. Run the following command within Claude Code.

/plugin marketplace add https://github.com/formio/ai.git
/plugin install formio-ai@formio

Claude Code prompts for the Project URL and the Base URL on install. These are described as follows:

• Project URL: This is the endpoint for your 'project'. If you are using our SaaS environment (https://portal.form.io), then your project URL will be a sub-domain, such as https://myproject.form.io. However, for most use cases, when Form.io is deployed in your own environment, then the project url is typically a 'sub-directory' structure like https://forms.mysite.com/myproject.
• Base URL: This is the endpoint for the deployment. If you are using the SaaS environment (https://portal.form.io), then this is always going to be https://api.form.io. However, for most use cases, when Form.io is deployed in your own environment, then this is the URL of the deployment like https://forms.mysite.com.

What you get

• Claude Code plugin: @formio/ai. One-command install. Bundles the MCP server and skill library, registers them with Claude Code.
• MCP server: @formio/mcp. Form.io operations (form_*, role_*, action_*, project_*) as MCP tools. Works with any MCP-aware client: Claude Code, Claude Desktop, VS Copilot, and whatever comes next.
• Skills library: Ten activatable skills covering app orchestration, form building (webforms and wizards), form embedding, resource planning, JSON-schema authoring, action configuration, authentication & authorization, the @formio/js SDK surface, and the full Form.io REST surface.

Why this exists

Form.io has been the data standardization layer for enterprise data for a decade. With the proliferation of AI coding agents, that standardization matters more, not less.

Build on the Form.io platform, not from scratch. The agent builds complete applications including the data models, forms, workflows, and business logic. Form.io is the platform it builds on. The APIs, data patterns, RBAC, audit infrastructure, and form management capabilities are production-grade and already there. The agent uses them as tools to build applications better.

Standardization across every AI-built app. One model, one set of rules, one audit trail, regardless of which team or which agent built it. With a standardization layer, multiple teams ship multiple applications, all with defensible, reconcilable data layers across the enterprise.

Governance built in. RBAC, group permissions, change history, audit trails — all emitted on the first pass. Every app lands inside the same compliance envelope the enterprise already runs on.

Agentic Skill Library

The plugin ships an activatable skill library. Claude loads the relevant skill on demand based on what you ask — you rarely need to name one explicitly.

Orchestration skills

Orchestration skills are special skills that serve as the entry point for most prompts. Rather than covering a single capability, they coordinate the other skills (planning, schema authoring, actions, deployment, framework scaffolding) to fulfill a broad, plain-language request end to end. When you describe what you want instead of which tool to use, an orchestration skill picks it up and drives the whole pipeline.

All skills

Examples and Use Cases

Ready-to-paste example prompts live in examples/ — each file is one self-contained prompt plus notes on what it should exercise. To try one, create a new folder, start Claude Code inside it, and paste the prompt:

mkdir form-app
cd form-app
claude

Build complete applications

Create a brand-new 'greenfield' form-based application — or introduce a new form-based feature within an existing one — using the formio-application orchestration skill. The agent plans the data model, imports it into your Form.io project, and scaffolds the front end, using the Form.io platform as the composable backend for the full application logic.

• CRM Application — clients, deals, and activity logs with owner-scoped access.
• Help Desk — customer tickets, agent workflows, internal notes, and email notifications.
• Storyboard — production → scene → shot hierarchy with collaborative crew access.

This library currently only supports the Angular application framework for new 'greenfield' applications. It generally supports other frameworks using the Vanilla JS @formio/js javascript renderer. Full support for other frameworks are coming soon.

Build forms and wizards

Create complex forms and multi-page conditional wizards with the formio-form-builder skill. The agent authors the form JSON and automatically creates the form within any stage of your deployment — including forms whose submission data must adhere to well-defined external schemas such as FHIR.

• College Application Wizard — multi-page wizard with program-driven conditional pages.
• FHIR-Compliant Patient Form — submission data that conforms to the FHIR Patient resource.
• Customer Feedback Form — conditional follow-up fields and a conditional email notification.
• Student Onboarding Wizard — create a wizard and embed it within your application in one pass.

Embed forms in existing applications

Embed an existing form or wizard within any HTML-based application using the formio-form skill.

• Embed an Existing Form — render a saved form with @formio/js, pre-fill it, and handle submit events.

Work the REST API via prompt

The formio-api skill knows the full REST surface of your Form.io deployment — create any Resource, Form, Submission, or other entity via prompt.

• Create a Patient Resource — create a new resource through the MCP server's first-party tools.

Using the MCP server without the skills

The bundled MCP server is also published standalone as @formio/mcp — you do not need the Claude Code plugin or the skill library to use it. Any MCP-aware client (Claude Code, Claude Desktop, Cursor, VS Code Copilot) can spawn the server directly and call the tools below.

It is also listed in the official MCP Registry as io.form/formio-mcp, so clients that browse the registry can discover and install it without any manual configuration.

One-click install

Both links pre-fill the server command and leave a placeholder FORMIO_PROJECT_URL for you to replace with your own project URL.

Manual configuration

Claude Code — add a .mcp.json to your project root:

{
  "mcpServers": {
    "formio-mcp": {
      "command": "npx",
      "args": ["-y", "@formio/mcp"],
      "env": {
        "FORMIO_BASE_URL": "https://api.form.io",
        "FORMIO_PROJECT_URL": "https://your-project.form.io"
      }
    }
  }
}

The same mcpServers block works in every other stdio-capable client — only the file it belongs in changes:

In standalone mode, FORMIO_BASE_URL and FORMIO_PROJECT_URL are required env vars (full list). Authentication works the same as in plugin mode: the first authenticated tool call opens the browser portal-login flow, or set FORMIO_API_KEY to skip the browser entirely.

Once connected, prompt the tools directly — no skill activation involved:

Using the formio-mcp tools, show me every form and role in my Form.io project, then export the full project template and save it to ./backup/template.json.

Using the formio-mcp form_create tool, create a new form called "Contact Us" with fields for full name (required), email (required), subject, and message, plus a submit button.

Ready-to-paste versions of these live in examples/mcp/: Inspect and Export a Project and Create a Form Directly.

One caveat: without the skills, the agent authors Form.io JSON (form schemas, action settings, access arrays) from its own general knowledge instead of the conventions the skill library encodes — every operation the tools cover still works, but you give up the guardrails. For other transports (Streamable HTTP for remote clients, SSE for Claude Desktop) and running the server from a clone of this repo, see the MCP server README.

MCP server tools

The bundled @formio/mcp server exposes these tools. Skills prefer these over raw HTTP whenever an operation is covered.

Authentication

The MCP server supports two authentication modes:

• JWT mode (default). A short-lived local Express server renders the Form.io portal login form; the user signs in once, the JWT comes back via a /callback endpoint, and formioFetch attaches x-jwt-token on every subsequent request. The flow is implicit — the first authenticated tool call triggers it on a cache miss. No explicit authenticate tool exists.
• API-key mode. Set FORMIO_API_KEY. All requests attach x-token; the browser flow is skipped entirely.

Login-form auto-resolution

When FORMIO_LOGIN_FORM is unset, the server probes these candidates on the first login attempt and caches the first one that responds (1.5-second timeout per candidate):

1. ${FORMIO_BASE_URL}/formio/user/login (portal-base)
2. ${FORMIO_PROJECT_URL}/admin/login (project admin)
3. ${FORMIO_PROJECT_URL}/user/login (project user)

The probe runs lazily — only when the local auth page is actually served.

Environment variables

* In plugin context, FORMIO_PROJECT_URL is captured per-cwd by the project_set tool and persisted to ~/.formio/projects.json. The verify-project-url SessionStart/PreToolUse hook offers formio_default_project_url (from plugin user-config) as the default the first time you enter a workspace.

Contributing

This is a pnpm + Turborepo monorepo: the @formio/mcp MCP server (packages/mcp-server/), the @formio/ai Claude Code plugin (plugin/, bundling the server + skill library), and the skill test suite (packages/skill-tests/). Setup, conventions, skill-authoring guidelines, and the release flow are in CONTRIBUTING.md. Security reports: SECURITY.md.
