mcp-use
A plugin with skills for building TypeScript MCP servers and MCP apps: the agent scaffolds, edits, debugs and verifies them
Medium risk
We rate an entry medium when the tool runs code, makes network calls or reads project files. Check what exactly it does before installing.
Why this level
- Creates and runs MCP server code on the developer machine
- May install npm packages while scaffolding a project
Install
Manual install
/plugin marketplace add mcp-use/mcp-use
/plugin install all-skills@mcp-useYou can install individual skills: mcp-builder, mcp-apps-builder, chatgpt-app-builder or openapi-to-mcp.
This is third-party code. Review the repository files before installing.
What it does
The mcp-use repository is a TypeScript framework for MCP: you build MCP servers, ChatGPT apps and Claude connectors with it, with a built-in inspector and Zod-typed schemas. Alongside the framework it ships a plugin with official skills the agent installs: mcp-builder for building and debugging servers, mcp-apps-builder and chatgpt-app-builder for apps with a UI, and openapi-to-mcp for turning OpenAPI into MCP. You can start a project with the create-app command, and the server serves a page with its connection URL and setup instructions. The skills give the agent a set workflow: scaffold, modify, debug, migrate and verify.
Who it is for. For developers building TypeScript MCP servers and apps who want the agent to run that work with a consistent workflow.
Good fit when
- You need to build a TypeScript MCP server from scratch
- You need an MCP app with a UI for ChatGPT or Claude
- You need to turn an existing OpenAPI spec into an MCP server
Not a fit when
- Your stack is not TypeScript and you are not moving to it
- You need a ready MCP server for a specific service, not to build your own
Example request
Build a TypeScript MCP server with a weather tool and a view cardLimitations
The skills and framework target TypeScript. This is a tool for building your own MCP servers and apps, not a ready connection to an external service. Deployment is offered via the manufact service, but local development does not require it.
How to disable. Uninstall the plugin via /plugin and, if you added the package, remove the mcp-use dependency from the project.
Security check
- Creates and runs MCP server code on the developer machine
- May install npm packages while scaffolding a project
README in short
The README presents mcp-use as a TypeScript framework to build, test and ship MCP servers, ChatGPT apps and Claude connectors. It highlights full Zod typing, native React views bound to tools, a built-in inspector and an agent-first, headless workflow. Quickstart: the create-app command, npm run dev and the browser inspector. The repository also ships a set of official skills for building servers and apps and converting OpenAPI into MCP. The package is on npm under an MIT license.
