Claude Code
claude mcp add --transport http context7 https://mcp.context7.com/mcp \
--header 'Authorization: Bearer YOUR_API_KEY'Claude Desktop and claude.ai
Custom connectors in Claude accept OAuth or no-auth servers only.
This server expects an API key in a header, so use Claude Code,
Cursor or VS Code instead, or the local setup below.Cursor

}Frequently asked questions
What is the Context7 MCP server?
It is a Model Context Protocol (MCP) server — a small piece of software that gives AI assistants like Claude a secure, governed connection to Context7. Up-to-date documentation for any coding framework. Version-specific docs injected directly into AI prompts.
Is there an official Context7 MCP server?
Yes. The Context7 MCP server is an official integration, maintained by the vendor or the Model Context Protocol project, which makes it the safest default for business use. It is maintained by Upstash (Context7).
Is the Context7 MCP server hosted, or do I run it myself?
Both. Context7 runs a hosted endpoint at https://mcp.context7.com/mcp, so most people just paste that URL into their AI client. You can also run the server locally with npx.
Do I need an API key for the Context7 MCP server?
Yes. The hosted server expects an API key from your Context7 account, sent in the Authorization header. Store it in your client's secret settings rather than pasting it into shared config files.
What can an AI assistant actually do with Context7?
Through this server an assistant can work with documentation, framework docs, version-specific, code context — reading from and acting on Context7 directly instead of you copy-pasting between windows. What you allow it to do is controlled by the permissions you grant.
How do I set this up for my business?
The setup section above has copy-paste config for Claude Code, Claude Desktop, Cursor and VS Code. Once it is running against real systems, the question becomes what catches it when it acts wrongly, which is what Crox's Safety Diagnostic looks at.

Already running this in production?
An agent with a live connection to your tools is a model that can act. Crox looks at what catches it when it acts wrongly: the layers around it, who can stop it, and where a near miss gets reported. Two days, one team, one model.
