Context7 MCP Server Details
Context7 MCP Server delivers up-to-date, code-first documentation and examples for LLMs and AI code editors by pulling content directly from the source. It supports multiple MCP clients and exposes tools that help you resolve library IDs and retrieve library documentation, ensuring prompts use current APIs and usage patterns. The repository provides installation and integration guides for Cursor, Claude Code, Opencode, and other clients, along with practical configuration samples and OAuth options for remote HTTP connections. This MCP server is designed to keep prompts in sync with the latest library docs, reducing hallucinations and outdated code snippets.
Use Case
Use Context7 MCP Server to fetch up-to-date library documentation and code examples directly into your prompts. It enables prompt authors to resolve a library name to a Context7-compatible ID and then retrieve precise docs for that library. Example usage:
{
"mcpServers": {
"context7": {
"url": "https://mcp.context7.com/mcp",
"headers": {
"CONTEXT7_API_KEY": "YOUR_API_KEY"
}
}
}
}This configuration allows MCP-enabled clients to fetch docs on demand, ensuring prompts reflect current APIs and usage patterns. For local development, you can run a local MCP server connection:
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"]
}
}
}You can also install in Claude Code or Opencode as shown in the docs:
Claude Code Local:
claude mcp add context7 -- npx -y @upstash/context7-mcp --api-key YOUR_API_KEYClaude Code Remote:
claude mcp add --header "CONTEXT7_API_KEY: YOUR_API_KEY" --transport http context7 https://mcp.context7.com/mcpOpencode Remote:
"mcp": {
"context7": {
"type": "remote",
"url": "https://mcp.context7.com/mcp",
"headers": {
"CONTEXT7_API_KEY": "YOUR_API_KEY"
},
"enabled": true
}
}Opencode Local:
{
"mcp": {
"context7": {
"type": "local",
"command": ["npx", "-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"],
"enabled": true
}
}
}The docs also explain how to enable OAuth for remote connections by changing the endpoint from /mcp to /mcp/oauth when needed:

OAuth is only available for remote HTTP connections. For local MCP connections using stdio transport, use API key authentication instead. API Key is recommended for higher rate limits.
API Key is recommended. Get a free API key at context7.com/dashboard for higher rate limits.
