any-chat-completions-mcp MCP Server

Integrate Claude with Any OpenAI SDK Compatible Chat Completion API - OpenAI, Perplexity, Groq, xAI, PyroPrompts and more.

This implements the Model Context Protocol Server. Learn more: https://modelcontextprotocol.io

This is a TypeScript-based MCP server that implements an implementation into any OpenAI SDK Compatible Chat Completions API.

It has one tool, chat which relays a question to a configured AI Chat Provider.

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To add OpenAI to Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json

On Windows: %APPDATA%/Claude/claude_desktop_config.json

You can use it via npx in your Claude Desktop configuration like this:

{ "mcpServers": { "chat-openai": { "command": "npx", "args": [ "@pyroprompts/any-chat-completions-mcp" ], "env": { "AI_CHAT_KEY": "OPENAI_KEY", "AI_CHAT_NAME": "OpenAI", "AI_CHAT_MODEL": "gpt-4o", "AI_CHAT_BASE_URL": "https://api.openai.com/v1" } } } }

Or, if you clone the repo, you can build and use in your Claude Desktop configuration like this:

{ "mcpServers": { "chat-openai": { "command": "node", "args": [ "/path/to/any-chat-completions-mcp/build/index.js" ], "env": { "AI_CHAT_KEY": "OPENAI_KEY", "AI_CHAT_NAME": "OpenAI", "AI_CHAT_MODEL": "gpt-4o", "AI_CHAT_BASE_URL": "https://api.openai.com/v1" } } } }

You can add multiple providers by referencing the same MCP server multiple times, but with different env arguments:

{ "mcpServers": { "chat-pyroprompts": { "command": "node", "args": [ "/path/to/any-chat-completions-mcp/build/index.js" ], "env": { "AI_CHAT_KEY": "PYROPROMPTS_KEY", "AI_CHAT_NAME": "PyroPrompts", "AI_CHAT_MODEL": "ash", "AI_CHAT_BASE_URL": "https://api.pyroprompts.com/openaiv1" } }, "chat-perplexity": { "command": "node", "args": [ "/path/to/any-chat-completions-mcp/build/index.js" ], "env": { "AI_CHAT_KEY": "PERPLEXITY_KEY", "AI_CHAT_NAME": "Perplexity", "AI_CHAT_MODEL": "sonar", "AI_CHAT_BASE_URL": "https://api.perplexity.ai" } }, "chat-openai": { "command": "node", "args": [ "/path/to/any-chat-completions-mcp/build/index.js" ], "env": { "AI_CHAT_KEY": "OPENAI_KEY", "AI_CHAT_NAME": "OpenAI", "AI_CHAT_MODEL": "gpt-4o", "AI_CHAT_BASE_URL": "https://api.openai.com/v1" } } } }

With these three, you'll see a tool for each in the Claude Desktop Home:

And then you can chat with other LLMs and it shows in chat like this:

Or, configure in LibreChat like:

chat-perplexity: type: stdio command: npx args: - -y - @pyroprompts/any-chat-completions-mcp env: AI_CHAT_KEY: "pplx-012345679" AI_CHAT_NAME: Perplexity AI_CHAT_MODEL: sonar AI_CHAT_BASE_URL: "https://api.perplexity.ai" PATH: '/usr/local/bin:/usr/bin:/bin'

And it shows in LibreChat:

Installing via Smithery

To install Any OpenAI Compatible API Integrations for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install any-chat-completions-mcp-server --client claude

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
