# 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](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:

```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](img/claude_desktop_home.png)



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



![Claude Chat with OpenAI](img/claude_chat_openai.png)



Or, configure in [LibreChat](https://www.librechat.ai/) 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:

### Installing via Smithery



To install Any OpenAI Compatible API Integrations for Claude Desktop automatically via [Smithery](https://smithery.ai/server/any-chat-completions-mcp-server):



```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](https://github.com/modelcontextprotocol/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.
