quietnotion/barevalue-mcp

Barevalue edits podcast audio. Your agent hands over a raw recording and gets back a finished episode, with noise and levels fixed and filler words and dead air removed, plus a transcript, show notes and highlight clips for longer episodes.
One call to sign up, no sign-in, 10 free hours of editing a month, delivered at up to 320 kbps or lossless. No payment details, and the agent does not operate an editor.
Streamable HTTP, nothing to install, no key needed to connect. The agent calls barevalue_register with your email address and gets a key in that one call.
Install
| Client | One line |
|---|---|
| Claude Code | claude mcp add --transport http barevalue https://barevalue.com/mcp |
| Claude Code, with the skill | /plugin install barevalue --marketplace barevalue-ai/barevalue-mcp |
| Claude (web and desktop) | Settings, Connectors, Add custom connector, then paste https://barevalue.com/mcp/connect |
| Cursor | Add "barevalue": { "url": "https://barevalue.com/mcp" } under mcpServers in ~/.cursor/mcp.json |
| ChatGPT | With developer mode on, add a connector and paste https://barevalue.com/mcp/connect |
| Any agent that reads skills | npx skills add barevalue-ai/barevalue-mcp |
| A file on your own disk | claude mcp add barevalue -- npx -y barevalue-mcp (the npm bridge, below) |
There are two addresses for the same server. https://barevalue.com/mcp is open: the agent registers itself and holds its own key. https://barevalue.com/mcp/connect asks you to sign in to your Barevalue account in a browser first, which is what the Claude and ChatGPT connector screens expect.
The Claude Code plugin line needs Claude Code 2.1.275 or later. On an earlier version, run claude plugin marketplace add barevalue-ai/barevalue-mcp and then claude plugin install barevalue@barevalue. The plugin adds the hosted server and the skill in skills/barevalue-podcast-editing, which teaches an agent the order of calls and what to do when one is refused. This repository is also a Cursor plugin (.cursor-plugin/plugin.json).
Cursor also takes an install link: cursor://anysphere.cursor-deeplink/mcp/install?name=barevalue&config=eyJ1cmwiOiJodHRwczovL2JhcmV2YWx1ZS5jb20vbWNwIn0=
The npm bridge, for a recording on your own machine
The hosted server takes a recording by link. For a file on disk it returns a curl command for the agent to run. The npm package barevalue-mcp does that step itself: barevalue_upload takes the path and sends the file.
| You have | Use |
|---|---|
| A recording that already has a link | The hosted server, https://barevalue.com/mcp |
| A recording on this machine (Claude Code, Cursor, any local agent) | Either. With this package the agent has no command to run |
The package is a bridge to the hosted server. Its tools come from the service (asked for when a client lists them, kept for five minutes), so they are always the current ones.

Or in any MCP client's configuration:
Node 18 or later.
API key
If your email address has no Barevalue account yet, you do not need one to start. The agent calls barevalue_register with the address and gets a key in that one call, which this server keeps for the rest of the session. You get an email with a link: until you click it the account can edit 30 minutes, after it 10 hours a month.
If the address already has an account, barevalue_register is refused and you make the key yourself (Settings, API Keys on barevalue.com). Set it and the tools stop asking for one:
What to say
