01 · Install Context7

Claude Code

claude mcp add upstash-context7 -- npx -y @upstash/context7-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "upstash-context7": {
      "command": "npx",
      "args": [
        "-y",
        "@upstash/context7-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package @upstash/context7-mcp - published under the repo owner's npm scope (@upstash)

registry namespace io.github.upstash is GitHub-verified and matches the repo owner

03 · What Context7 can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can resolve a general library name into a Context7-compatible library ID, and retrieve documentation for a library using a Context7-compatible library ID.

The 2 tools it gives your agent

Extracted from the project's README - what Context7 lets an agent do.

resolve-library-id: - Resolves a general library name into a Context7-compatible library ID.
query-docs: - Retrieves documentation for a library using a Context7-compatible library ID.

Limitations (from the README)

If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 can skip the library-matching step and directly retrieve docs. The slash syntax tells Context7 exactly which library to load docs for.
