What it does

Music Connect is an agent skill from ruvnet/ruflo. One-time setup — mint a Cognitum Music personal access token and register the cogmusic MCP server with Claude Code

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.

When your agent uses it

  • Tasks that involve MCP servers

Example prompts

  • “/music-connect”

Requirements

  • Node.js
  • A credential in COGMUSIC_TOKEN
  • Pre-approved tools (allowed-tools): Bash, WebFetch

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Check for an existing, working registration first
  2. If no token was provided, tell the user exactly how to mint one (this step requires their own browser login — you cannot do it for them)
  3. Register the MCP server once you have the token (never print the full token back to the user in plain chat if avoidable — treat it as a…
  4. Verify
  5. If registration already exists but is unhealthy, remove and re-add rather than editing config by hand
  6. Once connected, the mcpcogmusic* tools (list_productions, get_production, create_production, separate_stems, extract_midi, master) become…

What it can do on your machine

Read from SKILL.md and the folder at commit 6c04654. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • WebFetch

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • claude
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • music.cognitum.one

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • COGMUSIC_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Music Connect loads about 806 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 381 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~806

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, WebFetch

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Music Connect

Wires this session up to the user's own Cognitum Music account (music.cognitum.one) via the cogmusic MCP bridge. This is a one-time, per-machine/per-project setup — run it before any other music-* skill if mcp__cogmusic__* tools aren't already loaded.

When to use

  • The user asks to generate/produce music and no mcp__cogmusic__* tools are visible yet.
  • claude mcp get cogmusic reports the server missing, disconnected, or unhealthy.
  • The user is rotating or replacing an expired/revoked token.

Steps

  1. Check for an existing, working registration first:

    bash
    claude mcp get cogmusic

    If it reports ✔ Connected, you're already set up — stop here.

  2. If no token was provided, tell the user exactly how to mint one (this step requires their own browser login — you cannot do it for them):

    • Sign in at https://music.cognitum.one/mcp
    • Click "Generate connection token" (label it something recognizable, e.g. "Claude Code")
    • Copy the raw token — it starts with cogmcp_ and is shown exactly once

  3. Register the MCP server once you have the token (never print the full token back to the user in plain chat if avoidable — treat it as a secret; it's fine as a one-time argument to claude mcp add, which stores it in local config, not in conversation history):

    bash
    claude mcp add cogmusic --env COGMUSIC_TOKEN=cogmcp_... -- npx -y cogmusic@latest

    Pin to cogmusic@0.1.1 or later — earlier 0.1.0 has no fetch timeout and fails create_production calls that run past Node's ~5-minute default (see ADR-0001).

  4. Verify:

    bash
    claude mcp get cogmusic

    Expect ✔ Connected. If it shows CONNECTION_CLOSED or a 404, the cogmusic npm package version pinned in the command may be stale or unpublished — check npm view cogmusic version and retry with an explicit version.

  5. If registration already exists but is unhealthy, remove and re-add rather than editing config by hand:

    bash
    claude mcp remove cogmusic -s local
claude mcp add cogmusic --env COGMUSIC_TOKEN=cogmcp_... -- npx -y cogmusic@latest

  6. Once connected, the mcp__cogmusic__* tools (list_productions, get_production, create_production, separate_stems, extract_midi, master) become available — proceed to music-generate or music-list.

Notes

  • The token is a personal access token (PAT) scoped to one Cognitum account, minted and revoked by the user themselves at music.cognitum.one/mcp — this plugin has no way to mint or revoke one programmatically, and should never attempt to guess, cache elsewhere, or transmit it anywhere other than the local claude mcp add registration.
  • A newly-registered MCP server's tools may not appear until the next Claude Code session — if mcp__cogmusic__* tools still aren't listed after a successful claude mcp get cogmusic, tell the user to start a fresh session.
