An MCP server that bridges to multiple OpenAI-compatible LLMs - your AI rubber duck debugging panel
An MCP server that bridges to multiple OpenAI-compatible LLMs - your AI rubber duck debugging panel
An MCP (Model Context Protocol) server that acts as a bridge to query multiple LLMs -- both OpenAI-compatible HTTP APIs and CLI coding agents. Just like rubber duck debugging, explain your problems to various AI "ducks" and get different perspectives!
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
