mumo — VS Code extension
Multi-model responses + cross-model reactions. Want more rounds? Context carries automatically. Stop when you have what you need.
Claude, GPT, Gemini, Grok, Qwen, GLM, Kimi in parallel. For contested decisions — architecture, plan review, strategy — where a single model might be confidently wrong.
Invoke mumo from Copilot Chat — the agent routes through MCP, convenes the panel, and returns the models' synthesis inside VS Code.
The claim map at mumo.chat — each contested statement plus every model's reaction (keep, challenge, explore, core, shift). Not a consensus answer; the structure underneath it.
Context carries forward automatically — add follow-up rounds until you have what you need, without re-pasting anything.
What's in the box
- MCP server registration — wires
https://mumo.chat/api/mcp into VS Code's MCP provider registry. Seven tools: create_deliberation, wait_for_round, append_round, get_session, list_sessions, list_models, get_credit.
- Native key storage — uses VS Code's
SecretStorage (macOS Keychain / Windows Credential Manager / Linux libsecret). No MUMO_API_KEY env-var export required.
- Walkthrough — auto-opens on first install: create a key, paste it, try mumo in Copilot Chat.
- Status bar — shows
mumo when configured, mumo: no key otherwise. Click to set the key.
- Settings — override the server URL (
mumo.serverUrl) for self-hosted or staging endpoints.
- Commands —
mumo: Set API Key (re-prompt), mumo: Open Recent Sessions (opens mumo.chat).
Install
ext install mumo.mumo-vscode
Or search mumo in the Extensions panel. The Get Started walkthrough opens automatically on first install — three steps to get you to your first deliberation. Create your mumo API key at mumo.chat/settings/api-keys (keys start with mmo_live_).
Using the panel
In Copilot Chat (Agent mode), invoke mumo explicitly for reliable routing:
- "Ask mumo about…"
- "Run this by a mumo panel"
- "Get me a second opinion from mumo on…"
See mumo.chat/install for setup and mumo.chat/docs/mcp for the tool reference, the deliberation loop, and prompt patterns.
Why explicit invocation
Copilot's agent mode picks tools based on intent. Naming mumo in your prompt routes the call deterministically; vague phrasings like "ask a panel" may resolve to a different tool or a generic Copilot response. The panel is available whenever you mention mumo in Agent chat.
Requirements
- VS Code 1.101 or later (MCP extension API is stable as of this release)
- An active mumo account — sign up at mumo.chat
