HTTP Transport & OAuth

For cloud-based agents like ChatGPT, the MCP server is available over Streamable HTTP with OAuth 2.1 authentication (PKCE, RFC 8414, RFC 9728).

MCP Endpoint

https://mcp.llmrank.app/v1/mcp

OAuth Discovery

/.well-known/oauth-authorization-server

Supports MCP Authorization Spec: Dynamic Client Registration (RFC 7591), PKCE with S256, WWW-Authenticate with resource_metadata, and token refresh.

Frequently Asked Questions

What is the Model Context Protocol (MCP)?

MCP is an open standard created by Anthropic that lets AI coding agents connect to external tools and data sources. It provides a unified way for IDEs like Claude Code, Cursor, VS Code, and ChatGPT to call tools — in this case, the 27 SEO tools from LLM Rank.

Which AI coding agents support MCP?

Claude Code, Cursor, Claude Desktop, VS Code (via Copilot), Windsurf, ChatGPT, and Perplexity all support MCP servers. LLM Rank works with all of them — use stdio transport for local IDEs or the HTTP endpoint for cloud-based agents.

Do I need a paid plan to use the MCP server?

The MCP server works with any LLM Rank plan, including the free tier. Free accounts can crawl up to 10 pages per crawl with 2 crawls per month. Paid plans unlock higher limits and additional features like competitor analysis.

Is the MCP server open source?

Yes, the @llmrank.app/mcp package is MIT licensed and published on npm. The source code is available on GitHub.

How does the HTTP transport work for ChatGPT?

ChatGPT and other cloud-based clients use the Streamable HTTP transport at mcp.llmrank.app/v1/mcp. Authentication uses OAuth 2.1 with PKCE — the client discovers the authorization server via the /.well-known/oauth-authorization-server endpoint and completes the flow automatically.
