# Context7 MCP server

Install Context7 MCP server in Claude Code:

```bash
claude mcp add --scope user --transport http context7 https://mcp.context7.ai/mcp
```

Restart Claude Code, then `claude mcp list`. You want `context7` in that list.

Same command on [context7.ai](https://context7.ai).

## Installation

That command is the install. `--scope user` puts it in every project. Leave the flag off if you only want the current repo.

Optional API key (rate limits, private repos). Make one at [context7.ai/dashboard](https://context7.ai/dashboard), then:

`claude mcp add --scope user --header "Authorization: Bearer YOUR_API_KEY" --transport http context7 https://mcp.context7.ai/mcp`

### Claude Desktop, Cursor, VS Code, Windsurf

JSON config: under `mcpServers`, add `context7` with type `http` and url `https://mcp.context7.ai/mcp`. Drop-in files: [`examples/claude_desktop_config.json`](examples/claude_desktop_config.json), [`examples/cursor.json`](examples/cursor.json), [`examples/vscode.json`](examples/vscode.json), [`examples/windsurf.json`](examples/windsurf.json).

Claude Code plugin: [`plugins/claude/context7`](plugins/claude/context7). Skill: [`skills/context7-mcp/SKILL.md`](skills/context7-mcp/SKILL.md). MCP registry manifest: [`server.json`](server.json).

Remote HTTP vs local npx: this page is the remote. `npx ctx7 setup` and `npx -y @upstash/context7-mcp` are the local/stdio path. I use the remote so I do not run another Node process.

## Usage

Ask for something library-specific and add `use context7` to the prompt.

## Tools

Once it is connected you get Context7's tools, `resolve-library-id` and `query-docs`.

## Troubleshooting

`context7 mcp not connecting` / `context7 mcp server not found`: run `claude mcp list`. Missing means the add did not stick, or you skipped the restart. Listed but dead usually means you added both `mcp.context7.ai` and `mcp.context7.com` under the same name.

`spawn context7-mcp ENOENT` is a local stdio install that cannot find a binary. Use the remote HTTP command above.
