Overview

Description from the maker (original English)

Ask free LLMs (DeepSeek, GLM, Gemini, Mistral) for a second opinion from any MCP client.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory
  • You need to fill in: ONOMEO_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: ONOMEO_API_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions

Is onomeo safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ONOMEO_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 30 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

What can I use instead?

onomeo-mcp

An MCP server that lets your coding agent ask other LLMs for a second opinion. It talks to onomeo, an OpenAI-compatible API where a rotating set of models (DeepSeek, GLM, Gemini, Mistral and others) is free to call with no credit card.

Typical uses from Claude Code, Cursor, Cline or any other MCP client:

  • "Ask DeepSeek to review this diff and tell me what it would change."
  • "Send this regex question to three models and compare the answers."
  • "Which free models are up right now?"

onomeo is in public beta. Not every feature is guaranteed to work, and feedback is actively collected and very welcome: open an issue here or write to hello@onomeo.com. This server is written and maintained by the operator of onomeo.

Tools

ToolWhat it does
list_modelsLists the models served right now, split into free and pay-as-you-go, with the current free call limit. Needs no API key.
ask_modelSends a prompt to one model and returns the answer. model defaults to auto, which picks a healthy free model and reports which one answered.
compare_modelsSends the same prompt to 2-4 models in parallel and returns the answers side by side.

Setup

  1. Sign up at onomeo.com and create an API key. No card is required for the free models.
  2. Add the server to your client. Node.js 20 or newer is required.

Claude Code:

claude mcp add onomeo -e ONOMEO_API_KEY=your-key -- npx -y github:Owaid0723666/onomeo-mcp

Cursor, Claude Desktop, Cline, Windsurf and other clients that read an mcpServers block:

{

"mcpServers": { "onomeo": { "command": "npx", "args": ["-y", "github:Owaid0723666/onomeo-mcp"], "env": { "ONOMEO_API_KEY": "your-key" } } } }

Claude Desktop: download onomeo-mcp.mcpb from the latest release, open it, and paste your key when asked.

Limits and pricing

Checked on 2026-10-10; list_models always returns the live values.

  • Free models: 30 calls per 5 hours per account, refilled automatically. One call covers up to 50,000 characters.
  • Paid models (Claude, GPT, Grok, Gemini Pro and others): pay-as-you-go from a 5 USD top-up, no subscription.
  • compare_models uses one call per model.

Privacy

Free models are served through third-party free tiers, and several of them may use prompts for training. Each model page on onomeo states what is known. Do not send secrets or private code to free models.

Development

npm install

npm test # against a local stub ONOMEO_LIVE=1 ONOMEO_API_KEY=your-key npm test # one real call to "auto"

ONOMEO_BASE_URL overrides the API host.
