Any other MCP-compatible agent

Anchor follows the Model Context Protocol spec exactly. If your agent supports remote MCP servers with OAuth 2.0, it can use Anchor today — no extra work required.

• Transport: Streamable HTTP
• URL: https://mcp.anchor.cc/mcp
• Auth: OAuth 2.0 with PKCE, dynamic client registration enabled
• Scopes: none required — access is scoped to the signed-in user's Anchor permissions
