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 an external command exerciser/src/exerciser/_worker.py:113, exerciser/src/exerciser/concurrency.py:347, exerciser/src/exerciser/containment.py:492 и ещё 11

        proc = subprocess.run(  # noqa: S603 (fixed argv, no shell)

Executes code built at runtime exerciser/src/exerciser/differential.py:382, exerciser/src/exerciser/service_doubles.py:1794, tracelens/src/tracelens/enrich/external_invariants.py:192

        exec(snippet, ns)  # noqa: S102 — the corpus is our own fixed text

Runs an external command extension/src/bringup/serviceRunner.ts:213, extension/src/embedder/sidecar.ts:96, extension/src/graph/graphEnhancer.ts:760 и ещё 17

        const child = spawn(bash, ['-lc', script], hiddenBackgroundOptions({

Builds a file path from a variable extension/src/graph/changedFiles.ts:194, extension/src/harness/exerciseIngest.ts:478, extension/src/identification/callSiteContext.ts:55 и ещё 7

                stats.push({ file, mtimeMs: fs.statSync(path.join(root, file)).mtimeMs });

Dumps the whole environment exerciser/src/exerciser/_worker.py:71, exerciser/src/exerciser/concurrency.py:340, exerciser/src/exerciser/containment.py:402 и ещё 6

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.

Vinv — questions

Answers built from our own checks of this server.

Why is there no uptime for Vinv?

Vinv 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 vinv-mcp was installed 210 times last week.

How do I connect Vinv?

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 vinv-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Vinv?

The npm package vinv-mcp was installed 210 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Vinv open source?

Yes — it is published under the Apache-2.0 licence, written in Python, 45 stars on GitHub and 14 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
