What the code does

We read the source, 2 d ago · rules 995398eba69f

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Reads files and sends them to the network src/triage.ts:136
        const entries = await fs.promises.readdir(dir, { withFileTypes: true });

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Optional settings from the registry entry, left out of the block above: TAG_PER_TRACK_API_KEY (Studio API key (tpt_live_...) generated on https://tag-per-track.cloud. Consumes prepaid credits, no crypto wallet needed. Takes priority over the wallet mode), WALLET_PRIVATE_KEY (Private key of a dedicated Base burner wallet (66 hex chars starting with 0x) for USDC micro-payments via x402. Used only when no API key is set), MAX_SPENDING_USDC (Client-side spending cap per request in USDC (wallet mode)), TAG_PER_TRACK_NO_PERSIST (Set to 1 or true to keep API-key analyses out of your dashboard history).

Tag-per-Track — questions

Answers built from our own checks of this server.

Why is there no uptime for Tag-per-Track?
Tag-per-Track runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package tag-per-track-mcp was installed 75 times last week.
How do I connect Tag-per-Track?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls tag-per-track-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Tag-per-Track?
The npm package tag-per-track-mcp was installed 75 times in the last week. Week over week that is +47%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Tag-per-Track open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
