Overview

The any-chat-completions-mcp server extends your MCP-enabled environment by providing a standardized bridge to any OpenAI-compatible API. Instead of being locked into a specific provider, developers can route requests to alternative backends like Groq, Perplexity, or xAI. This is particularly useful for leveraging specialized models—such as those optimized for extreme speed or real-time web search—directly within your AI agent's toolset. Integration is straightforward: you simply configure the base URL and API key for your chosen provider. By decoupling the interface from the backend, it allows for easy model swapping and benchmarking without rewriting your core integration logic.

Highlights

Connects any OpenAI-compatible API to MCP clients
Supports Groq, xAI, Perplexity, and self-hosted LLMs
Simple configuration via base URL and API keys
Enables rapid model switching for specialized tasks
Eliminates provider lock-in for chat completion workflows

Development

Install dependencies:

bash

npm install

Build the server:

bash

npm run build

For development with auto-rebuild:

bash

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:

json

{
  "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:

json

{
  "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:

json

{
  "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:

!Claude Desktop Home with Chat Tools

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

!Claude Chat with OpenAI

Or, configure in LibreChat like:

yaml

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:
!LibreChat with Perplexity Chat

Installing via Smithery
To install Any OpenAI Compatible API Integrations for Claude Desktop automatically via Smithery:
bash
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:
bash
npm run inspector
The Inspector will provide a URL to access debugging tools in your browser.
