Overview

Description from the maker (original English)

Multi-model deliberation over MCP: full responses plus typed cross-model reactions from other labs.

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 in the cloud
  • Transport: Streamable HTTP
  • Category: Other
  • You need to fill in: Authorization

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

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

You need

Which app do you use?

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

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http mumo https://mumo.chat/api/mcp --header 'Authorization: Bearer {MUMO_API_KEY}'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "mumo": {
      "url": "https://mumo.chat/api/mcp",
      "headers": {
        "Authorization": "Bearer {MUMO_API_KEY}"
      }
    }
  }
}

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": {
    "mumo": {
      "type": "http",
      "url": "https://mumo.chat/api/mcp",
      "headers": {
        "Authorization": "Bearer {MUMO_API_KEY}"
      }
    }
  }
}

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 address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

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

Values you fill in

  • Authorization secret required HTTP header
    mumo platform API key as a bearer token. Create one at https://mumo.chat/settings/api-keys (keys begin with mmo_live_).

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

What it can do

Common questions

Is mumo 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: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) 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. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

mumo — multi-model deliberation over MCP

Your agent sends a question to models from different labs — Claude, GPT, Gemini, Grok, DeepSeek, Kimi, and more — and gets back their full responses plus typed cross-model reactions. The participating models react to each other directly and explain, in their own words, what they agree with, challenge, or want to explore further. Built for architecture, plan/spec review, strategy, and pre-launch pressure tests. Free monthly credit; API key required.

The server is remote. There is nothing to run locally.

https://mumo.chat/api/mcp

Install

One-click, per host — each page walks through the key and the client's own install flow:

HostInstall page
Claude Codehttps://mumo.chat/install/claude-code
Cursorhttps://mumo.chat/install/cursor
Codexhttps://mumo.chat/install/codex
VS Code (Copilot)https://mumo.chat/install/vs-code
Grok Bothttps://mumo.chat/install/grok-bot
Hermes Agenthttps://mumo.chat/install/hermes
OpenClawhttps://mumo.chat/install/openclaw
Anything elsehttps://mumo.chat/install

Any MCP client that supports Streamable HTTP with a custom header:

{

"mcpServers": { "mumo": { "url": "https://mumo.chat/api/mcp", "headers": { "Authorization": "Bearer mmo_live_YOUR_KEY_HERE" } } } }

Get a key at mumo.chat/settings/api-keys (sign-in required; keys start with mmo_live_). initialize and tools/list work without a key, so your client can inspect the tools before you create one; tool calls need the header.

Tools

ToolWhat it does
create_deliberationStart a deliberation. Returns an ack immediately (session_id + round_id); the models run in the background.
wait_for_roundBlock on cheap progress polling until the round is done, then return every model's response and the claim map.
append_roundAdd a follow-up round, optionally steered with typed snippets (KEEP / EXPLORE / CHALLENGE / CORE / SHIFT).
get_sessionRead full session state: rounds, responses, snippets, claim maps.
share_sessionShare a session at its public URL; returns the page plus .md and .brief.md machine twins.
list_sessionsList your prior sessions.
list_modelsList the models available to your account, with pricing.
get_creditRead your credit balance.

Full reference, request and response shapes, and per-client notes: https://mumo.chat/docs/mcp. Machine-readable descriptors: /.well-known/mcp.json (manifest) and /api/mcp/server-card (MCP Server Card). Registry name: chat.mumo/mcp.

The loop

  1. create_deliberation with the question, written in the operator's first person ("I'm deciding whether to…").
  2. wait_for_round — panels take 15–120 s; a long wait is normal.
  3. Read the claim map before the prose. Steer with append_round and snippets, or stop.

The panel is advisory. Read the disagreement; don't defer to whichever side has more votes.


This repo: the client baseline

Beyond the server, mumo ships a skill for each host that teaches the agent when to convene a panel and how to read one. This repo is the source of truth for that skill: one tokenized SKILL.template.md plus a per-client overlay, rendered into each sibling client repo by the build script in scripts/. Never edit a client's SKILL.md directly — edit here and re-render.

├── SKILL.template.md # tokenized baseline (the source of truth) ├── playbooks/ # shared cognitive-shape playbooks └── references/ # shared reference docs (claim maps, snippets, takeaway, etc.) scripts/ ├── build-skill.js # renderer: template + per-client overlay -> client SKILL.md ├── README.md # how the build system works └── clients/ # per-client configs + Setup/Frontmatter partials server.json # Official MCP Registry descriptor (chat.mumo/mcp)

The template uses {{TOKEN}} markers for per-client substitution points (application name, moderator example, install URL, tool-naming registry note, etc.). Each scripts/clients/ .json fills them in.

Building
node scripts/build-skill.js                      # render to all six sibling client repos

node scripts/build-skill.js --target # render one node scripts/build-skill.js --verify-all # check for drift across all six (use in CI)

See scripts/README.md for details (token reference, adding a new client, etc.).

Editing
  • Shared kernel changes → edit skills/mumo/SKILL.template.md. Re-render to propagate.
  • Per-client overlay changes (## Setup body, frontmatter, application name, moderator example, install URL, tool-naming note) → edit scripts/clients/ / partials or scripts/clients/ .json tokens. Re-render.
  • Shared playbooks / references → edit skills/mumo/playbooks/ or skills/mumo/references/. Currently propagated manually; build-system handling is a follow-up.
Architecture

The shared-sections + per-client-overlay model is documented in docs/MCP_CLIENTS.md in the main mumo repo. The 2026-05-20 audit at docs/audits/2026-05-20-mcp-skill-delta.md enumerates exactly which sections are shared vs. per-client.
