Steps

Open Context7's MCP client setup instructions
context7.com/docs/resources/all-clients
Add the Context7 MCP server to your client
Add https://mcp.context7.com/mcp as a remote MCP server that uses the Streamable HTTP transport (often labelled "http").
context7.com/docs github.com/upstash registry.modelcontextprotocol.io/v0.1
Recommended: Authorization
context7.com/docs registry.modelcontextprotocol.io/v0.1
To sign in with OAuth instead of an API key, use the OAuth endpoint
Context7 supports MCP OAuth for remote connections at a separate endpoint: https://mcp.context7.com/mcp/oauth. Use that URL instead of the standard one and approve access in your browser. Context7's ChatGPT setup and its Codex plugin use OAuth.
context7.com/docs
List the server's tools
Your client should list the server's tools. That confirms the connection, not every API permission.
