Agent Rails Index

Overview

Agent Rails Index is an MCP server that provides a source-cited index of rails autonomous agents can use to earn, covering payers, settlement channels, and gates. By exposing this data through the Model Context Protocol, it lets AI assistants query and use the index as callable tools without manual copy-pasting between applications.

The server runs as a remote endpoint at https://penny-mcp-rails.penny-mcamp.workers.dev/mcp with no local installation required and no authentication needed. The latest release is v2026.10.11, available through the vendor website at https://penny-mcp-rails.penny-mcamp.workers.dev/.

Agent Rails Index is listed in the AI & Agents category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, you can claim this listing to verify ownership and keep information up to date.
