LocalAbout any-chat-completions-mcp MCP Server
any-chat-completions-mcp is a TypeScript MCP server that connects Claude to any OpenAI SDK compatible Chat Completions API. It suits users who want Claude to query providers such as OpenAI, Perplexity or Groq. Multiple providers can be configured by registering the server more than once.
Key features
- 01Single chat tool that relays questions
- 02Compatible with OpenAI SDK Chat Completions APIs
- 03Multiple providers through repeated server entries
- 04Installation via npx or local build
Use cases
- 01Querying other LLMs from Claude Desktop
- 02Connecting Perplexity to LibreChat as a tool
- 03Debugging the server with MCP Inspector
MCP support
The project is an MCP server that exposes a chat tool to MCP clients, forwarding questions to the configured AI chat provider.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project READMEany-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.

Comments
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
