/Context7 MCP, explained

Context7 is an MCP server by Upstash that gives AI coding agents access to current, version-specific documentation and code examples for software libraries and frameworks. Instead of relying on outdated training data, agents can query Context7 to retrieve docs straight from the source, reducing hallucinated APIs and stale code generation.

It works in two modes: a CLI + Skills mode where an installed skill guides the agent to fetch docs using ctx7 CLI commands, and an MCP mode where the agent calls documentation tools natively. It integrates with clients like Claude, ChatGPT, Cursor, and VS Code, and can be set up with a single npx command.

An API key from context7.com is recommended for higher rate limits, and requests are authenticated via a Bearer token. The MCP server source is open source under the MIT license, while the API backend, parsing engine, and crawling engine are private.

Context7 library projects are community-contributed, and the maintainers note they cannot guarantee the accuracy or security of all documentation.

Let your AI install it

Claude ChatGPT Gemini Grok

Opens the chat with the message ready. You choose whether to send it; if it doesn't appear, paste this page's link.

/How to install

You need: Any Claude plan. The free plan allows 1 custom connector; on Team or Enterprise the organisation owner adds it first.

In claude.ai or the Claude app, open "Customize" → "Connectors".

Press "+ Add" and choose "Add custom connector".

Type a name you'll recognise, paste the URL below and press "Continue".

For authentication choose "No sign in", press "Continue" and then "Add".

https://mcp.context7.com/mcp

Afterwards: In a chat, press "+" at the bottom left → "Connectors" and turn it on.

You need: A paid ChatGPT account: it may not be available on the free plan. ChatGPT now calls connectors "Plugins".

Go to chatgpt.com/plugins.

Press "+" and choose "Add custom MCP server".

Type a name and a description, and paste the URL below under "Connection".

Don't set up authentication. Accept "I understand and want to continue" and press "Create as a plugin".

https://mcp.context7.com/mcp

Afterwards: In a new chat, type @ and pick the plugin.

You need: The Gemini app doesn't support custom connectors yet. It's done with Gemini CLI from the terminal, which needs a Gemini Code Assist license (it no longer has a free tier).

Install Gemini CLI if you don't have it yet.

In the terminal, run the command below.

Open Gemini CLI and type /mcp to check it shows up.

gemini mcp add --transport http -s user context7 'https://mcp.context7.com/mcp'

Afterwards: Ask as usual: Gemini will use the connector when it needs it.

You need: A Grok account. On Grok Business or Enterprise, an admin turns it on first.

Go to grok.com/connectors.

Press "New Connector" and choose "Custom".

Paste the URL below and save.

https://mcp.context7.com/mcp

Afterwards: Grok will use the connector whenever your question needs it.
