Conversation
Multi-model deliberation as MCP tools, with an auto-triggering skill. Consults a panel of models (Claude, GPT, Gemini, Grok, Qwen, GLM, Kimi) on contested decisions where a single model might be confidently wrong — architecture choices, plan reviews, pricing tradeoffs, strategic decisions. Mirrors the plugin package published at github.com/mumo-chat/mumo-mcp (also listed in anthropics/claude-plugins-official for Claude Code). Same .claude-plugin/plugin.json, same .mcp.json, same skills/mumo/SKILL.md — shared canonical source in the mumo-mcp repo, copied here so knowledge-work-plugins stays self-contained. HTTP MCP server at https://mumo.chat/api/mcp, bearer auth via MUMO_API_KEY. See https://mumo.chat/mcp for tool reference and the deliberation loop.

What
Adds
mumoto thepartner-built/plugins and a corresponding entry to.claude-plugin/marketplace.json.Who we are
mumo (by Sourced LLC) is a multi-model deliberation platform at mumo.chat. Users consult a panel of frontier + cost-efficient models (Claude, GPT, Gemini, Grok, Qwen, GLM, Kimi) on contested decisions where a single model might be confidently wrong — architecture choices, plan reviews, pricing tradeoffs, strategic framing calls, pre-launch pressure tests.
What's in the plugin
https://mumo.chat/api/mcp, five tools:create_deliberation,append_round,get_session,list_sessions,list_modelsskills/mumo/SKILL.mdtells the agent when to reach for the panel (architecture tradeoffs, plan reviews, contested decisions) and when to skip (factual lookups, routine refactoring, code gen from a clear spec)Why it fits Cowork
Cowork targets knowledge workers making contested decisions — legal, finance, marketing, ops, strategy. That's exactly the population that benefits most from structured multi-model deliberation: a panel catches things a single model would confidently miss. Unlike the domain-specific plugins in this marketplace (sales, legal, finance, etc.), mumo is cross-domain — any role making a decision with multiple defensible framings.
Auth
Users create a mumo API key at mumo.chat/settings/api-keys (keys begin with
mmo_live_) and export it asMUMO_API_KEY. The plugin's.mcp.jsonresolves${MUMO_API_KEY}as the bearer token at install time.Consistency with Claude Code marketplace
Same plugin package was submitted to
anthropics/claude-plugins-officialasmumoon 2026-04-21 (review pending). This PR proposes the same plugin forknowledge-work-pluginsso Cowork users can install from their native plugin browser. If the Claude Code submission surfaces feedback we need to address, we'll mirror any changes here.Canonical source
github.com/mumo-chat/mumo-mcp— the plugin files copied here are identical to that repo. Keeping the same package across both marketplaces ensures parity for users who install on both Claude Code and Cowork.Test
Plugin installs and runs end-to-end against Claude Code via direct install from this fork. Cowork install pending merge so the
Browse pluginsUI picks it up.
