Review first — review before installing

Open the source and read safety notes before installing.

Safety notes

  • Webiny MCP is a guidance and skill-loading server; it does not directly manage a Webiny CMS deployment or execute Webiny admin actions.
  • The configure command can update supported agent configuration, so review generated MCP config changes before committing or sharing them.
  • The --skills and --additional-skills flags make the server recursively discover SKILL.md files from local directories; point them only at trusted project guidance.
  • Agent-loaded skills can strongly steer code changes, architecture decisions, and generated commands; review outputs before applying them to production Webiny projects.

Privacy notes

  • Skill files can contain internal coding conventions, project architecture, extension patterns, package notes, and proprietary implementation guidance.
  • Loaded skill content may be sent to MCP clients, model providers, chat transcripts, and logs when an agent requests it.
  • Custom skill directories can reveal local repository structure and file paths through tool output or error messages.
  • Keep credentials, customer data, private deployment details, and unpublished roadmap notes out of SKILL.md files exposed through the MCP server.

Prerequisites

  • Node.js and npx available for running the @webiny/mcp package.
  • A Webiny project or Webiny-related repository where the agent should use Webiny guidance.
  • Review of the built-in skills and any custom SKILL.md directories before exposing them to a model.
  • Agreement on whether project conventions, extension architecture, package internals, or private implementation notes may be sent to the MCP client and model provider.

About this resource

Content

Webiny MCP Server is the official MCP package from Webiny for exposing Webiny skills and development guidance to AI coding agents. It runs over stdio and provides tools for listing available Webiny skills and loading the exact skill content an agent needs for a task.

Use it when Claude, Cursor, Copilot, Windsurf, opencode, or another agent is working in a Webiny codebase and needs project-specific guidance before editing extensions, packages, configuration, or Webiny framework code.

Source Review

These sources were reviewed on 2026-06-06. Prefer the live repository, MCP package metadata, npm registry metadata, root license, CLI implementation, MCP server implementation, agent configuration implementation, agent discovery, instruction output, and sample MCP config for current behavior.

Features

  • Run a stdio MCP server with webiny-mcp serve or npx @webiny/mcp serve.
  • List available Webiny skills with list_webiny_skills.
  • Load a specific Webiny skill with get_webiny_skill.
  • Discover built-in package skills plus custom SKILL.md directories.
  • Override the base skills directory with --skills.
  • Add higher-priority custom skill directories with repeated --additional-skills flags.
  • Configure supported agents with webiny-mcp configure <agent>.

Installation

Run directly with npx:

npx @webiny/mcp serve

Configure Claude with the Webiny helper:

npx @webiny/mcp configure claude

For manual JSON configuration:

{
  "mcpServers": {
    "webiny": {
      "command": "npx",
      "args": ["@webiny/mcp", "serve"]
    }
  }
}

Restart the MCP client after adding the server.

Use Cases

  • Ask Claude to list available Webiny skills before making a Webiny code change.
  • Load Webiny extension guidance before editing extensions/ or webiny.config.tsx.
  • Load Webiny package guidance before editing core framework packages.
  • Add a project-local SKILL.md directory for organization-specific Webiny conventions.
  • Keep multiple coding agents aligned on the same Webiny development guidance.

Safety and Privacy

Webiny MCP Server exposes instructions rather than executing CMS operations, but those instructions can still shape large code changes. Review loaded skills and agent-generated edits before applying them to production Webiny projects.

Only expose trusted SKILL.md directories. Skills may contain private architecture notes, repository conventions, extension patterns, deployment assumptions, or proprietary guidance that will be sent to the MCP client and model provider when requested.

The configure command can write agent-specific configuration. Review those changes before committing config files or sharing them with a team.
