MCP Debugger CLI

OAuth Client Metadata for MCP 2025-11-25 Specification

Client ID Metadata Document

This page hosts the Client ID Metadata Document for mcp-debug, enabling OAuth authentication with MCP servers that support CIMD.

Client ID:
https://giantswarm.github.io/mcp-debug/client.json

How It Works

When connecting to an OAuth-protected MCP server, mcp-debug uses this URL as its client identifier. The authorization server fetches the metadata from this URL to learn about the client's configuration, including allowed redirect URIs and grant types.

This approach follows the MCP 2025-11-25 specification for client registration without requiring pre-registration with each authorization server.
