A hosted Context7 MCP server that supplies current library documentation and code examples to an AI coding agent. It is accessed remotely and can use an optional authorization key.

Connecting an AI coding environment to Context7 for on-demand documentation lookup. The input does not describe other jobs it supports.

It lets the agent retrieve documentation during a coding session instead of relying only on remembered information. This helps when APIs or library versions have changed.

About the project

Context7 is a documentation service that puts current, version-specific library documentation and code examples into prompts for large language models and AI coding editors. Developers use it to help coding agents produce answers based on the libraries they actually use; the catalogue entries provide ways for agents to access Context7 through its CLI or MCP server.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/upstash/context7

Made for: Claude Code.

Or install context7, the plugin that ships this one along with the rest of its 1 MCP server.

Security

Grade A, and why

context7 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
