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.

Runs a command on install [пакет] package.json:1

postinstall: node scripts/preflight-native.mjs && node scripts/postinstall-app.mjs && node scripts/postinstall-control-plane.mjs

Runs an external command packages/app/src/main/ollama-control.ts:219, packages/vscode-extension/src/reindex-queue.ts:40, packages/vscode-extension/src/spawn-cli.ts:39 и ещё 13

      const child = spawn(bin, ['serve'], { detached: true, stdio: 'ignore' });

Builds a file path from a variable src/bundles.ts:357, src/indexer/edge-resolvers/fastapi-mounts.ts:75, src/indexer/edge-resolvers/php-imports.ts:63 и ещё 22

    const fp = path.join(BUNDLES_DIR, entry.file);

Builds a database query by concatenation .github/workflows/verify-win-update.yml:53

      - name: Update a real install from the published release
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Touches key and credential files .github/workflows/ci.yml:137, hooks/trace-mcp-launcher.ps1:569, hooks/trace-mcp-launcher.sh:723 и ещё 2

              - '.npmrc'

Dumps the whole environment tsup.config.ts:160

    GA_MEASUREMENT_ID_INJECTED: JSON.stringify(process.env.TRACE_MCP_GA_MEASUREMENT_ID ?? ''),

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.

Trace MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Trace MCP?

Trace MCP 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 trace-mcp was installed 2 317 times last week.

How do I connect Trace MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls trace-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Trace MCP?

The npm package trace-mcp was installed 2 317 times in the last week. Week over week that is +387%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Trace MCP open source?

Yes — it is published under the MIT licence, written in TypeScript and 175 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.
