OmniSeek

by Battam1111version 0.2.1i★ –iRuns on your computer
Registry nameio.github.Battam1111/omniseek

Install

Overview

Description from the maker (original English)

Your agent seeks what search can't find. A self-hosted perception MCP server.

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: Streamable HTTP
  • Category: Search & AI memory

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).
  • The registry lists no key to fill in.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

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

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "omniseek": {
      "command": "uvx",
      "args": [
        "omniseek"
      ]
    }
  }
}

Run this in your terminal

claude mcp add omniseek -- uvx omniseek

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "omniseek": {
      "command": "uvx",
      "args": [
        "omniseek"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "omniseek": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "omniseek"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Basic checksi

We check information anyone can see; we have not read the code. Checks that do not apply are left out of the count. · Checked Nov 10, 2026

Compared with others in Search & AI memoryi

  • More stars than 0% of the other 5833 servers in this category
  • Published to the registry more recently than 41% of the other 5833 servers in this category
  • Basic checks equal to or better than 100% of the other 5833 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is OmniSeek 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (0.2.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv), Docker on your computer.

What can I use instead?

Give your AI agent the parts of the internet web search doesn't reach.

OmniSeek is an add-on for AI assistants and agents like Claude Code, Cursor, and Codex that lets them search where web search stops.

  • Ask in English, get what people actually said on Bilibili, and Zhihu when you ask for it, with links to the original posts.
  • Get the papers a research field is built on, and the recent ones building on them, in one answer.
  • Have your agent watch a topic and tell you only what is new since last time.
uv tool install omniseek

claude mcp add omniseek -- omniseek

Runs on your own computer. It plugs in through MCP, the standard way AI apps like Claude Code and Cursor add tools. Cursor and Codex: one line each, see Install.

Languages: English · 中文 · 日本語

See the difference

We asked two agents for Mu Li's exact words on the Transformer paper's writing, and the minute, in his 87-minute Bilibili walkthrough: web search returned a paraphrase and "around minutes 1 to 8", while the agent with OmniSeek transcribed the video and found the line at 1:21:51.

The full comparison on three questions, with sources, dates, and a short video.

What your agent can reach

  • Chinese communities: Bilibili videos and comments, Zhihu answers when you ask for them, recent V2EX threads, all with links to the posts. More: Bilibili, Zhihu
  • Across languages: ask in English, search in Chinese, answer in English. And the reverse. More
  • Podcasts and videos: turns speech into text on your own computer and quotes it with the minute (optional add-on). More
  • Research papers: which papers a field is built on and which recent ones cite them. More
  • New since last time: save a search once; each rerun shows only what is new. More
  • Sites you log in to: if you switch it on, your agent reads them through your own browser login. Off by default. More

It also keeps what it finds in a local index on your computer, so later searches start from what it already knows.

Install

The two commands above are all you need, with Python 3.11 or newer (uv installs it if you don't have it). Your AI app starts OmniSeek when it needs it. Nothing to keep running, no port to open.

Cursor, Codex, pipx, Docker, and the optional add-ons (podcast transcription, PDF reading, sites you log in to) are in [Install](https://github.com/Battam1111/omniseek/blob/main/docs/install.md).

Your data, your logins

OmniSeek runs on your computer. There is no OmniSeek cloud, no account, no telemetry: your agent's searches go straight to the sites you turned on. Public sites are on by default. Sites that need a login are off until you switch them on, and then they use the login already in your own browser; OmniSeek never sees your password. What it builds up as you use it stays in local files you own.

OmniSeek has no AI model of its own and sends nothing to a server of ours. Your agent does the thinking; OmniSeek goes and gets things. Settings: Configuration.

Tools

Your agent starts with omniseek_search. The rest, from paper maps to saved searches and the notes your agent keeps (omniseek_ruling, omniseek_statement), are in [tools.md](https://github.com/Battam1111/omniseek/blob/main/docs/tools.md).

[How we test these claims](https://github.com/Battam1111/omniseek/blob/main/bench/DESIGN.md): a test only counts if we first checked that plain web search could not find its answer on the first page (latest results). Using Claude Code? skills/omniseek-investigate is a ready-made research method: search wide, narrow in, add structure.

Contributing

See CONTRIBUTING.md: a new source has to find something plain web search doesn't. Fixing a source that stopped working is always welcome. Run python tests/smoke.py before you push.
