概览

AI 生成的概览

让编程助手通过 onomeo API 向免费第三方大模型（DeepSeek、GLM、Gemini、Mistral）提问，获取第二意见或并排对比答案。

可以做什么
  • 列出当前提供的模型，区分免费与按量付费，并显示实时免费调用额度
  • 向单个模型发送提示词，或由 auto 自动挑选可用的免费模型并说明由哪个模型作答
  • 把同一提示词并行发给 2 到 4 个模型，并排返回各自答案
适用场景
适合想就代码改动、正则表达式或设计问题听取其他模型意见时使用，也适合一次性比较多个模型的回答。
运行要求
以 stdio 本地进程运行，需要 Node.js 20 或更高版本。需要 onomeo 账号和 API 密钥，通过环境变量 ONOMEO_API_KEY 提供（免费注册，免费模型无需信用卡）。需要访问 onomeo API 的网络；可用 ONOMEO_BASE_URL 覆盖接口地址。
安装前请注意
免费模型经由第三方免费额度提供，其中若干可能将提示词用于训练，请勿发送密钥或私有代码。免费额度有限（撰写时为每账号每 5 小时 30 次调用），compare_models 每个模型消耗一次调用。付费模型按量计费，最低充值 5 美元。服务处于公开测试阶段，并非所有功能都保证可用。

安装

在 SourceWeft 中

  1. 打开 控制台中的 onomeo，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

README

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 [email protected]. 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:

sh
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:

json
{  "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

sh
npm installnpm test                                          # against a local stubONOMEO_LIVE=1 ONOMEO_API_KEY=your-key npm test    # one real call to "auto"

ONOMEO_BASE_URL overrides the API host.
