Worth knowing before you connect it

5 tools are described as changing something (generate_from_app, generate_image, generate_video, …): our AI model's reading of the descriptions, not something we tested. We did not call them.
2 packages with a critical or high advisory (0 critical, 2 high) in its dependencies (as resolved on 2026-10-24).

What it mainly works on, as our AI model read its tool descriptions: accounts and data in outside web services.

Each quoted sentence is the first sentence of the publisher’s own description. The kind of tool and the “changes data” mark are our AI model’s reading of that description, not something we tested: two differently worded runs had to agree, otherwise no label is shown, and nobody has checked them by hand. A tool without the “changes data” mark is described as only reading, searching or calculating, or the two runs did not agree. No tool was called. Read the publisher’s full description before relying on it. “Publisher declares” lists the hints the server itself sends with the tool (MCP annotations: read-only, destructive, idempotent, open-world); they are the publisher's claims, not checked by us. Inputs are the parameters in the tool's own input schema: name, declared type, whether it is required, and the first sentence of its description. Read 2026-10-23.

How well are its tools described?

Features #4 and #5

How clearly this server's own tool descriptions say what a tool does, and how consistent its tool list is. The first part is an AI model's yes/no reading of each description; the second part is counted. We do not turn it into a grade.

Descriptions

AI reading of each description

Says what the tool does: 100% of 10 tools
Says what it returns: 90% of 10 tools
States limits, defaults or errors: 67% of 9 tools
Says when to use it: 20% of 10 tools
Items covered per tool: 2.8 of 4 on average

Counted from the listing

Parameters with a description: 89% of 44
Tools with a description: 100% of 10
Typical description length: 233 characters

The tool set

Counted from the listing

Tools: 10
Size of the list: about 2,438 tokens for an agent to load (characters ÷ 4)
Naming: 9 of 10 names use snake_case

AI reading: easy to mix up

No pair found.

The AI items cover 10 of 10 tools: for a tool where two differently worded runs disagreed, that item is left out. They were not checked by hand, and no tool was called. “Easy to mix up” means two tools whose names or descriptions overlap without saying how they differ; the AI found none. We do not rate whether the tool set is complete or whether side effects are spelled out, because our AI reading of those was not reliable enough.

Optional settings the entry also lists (left out above): TANVO_API_KEY, TANVO_OUTPUT_DIR.
This runs the publisher's code on your machine (npx). Read its README first.
The MCP Inspector lists the server's tools, resources and prompts; a tool you call there runs for real.

Built from the server's registry entry with each client's documented format (checked 2026-10-14; the Cursor link and the VS Code command 2026-10-19; the MCP Inspector command 2026-10-21). Values in < > are yours to fill in; this page never contains a key. Where the server needs a setting the entry does not declare, it can still fail to start.

Common questions about ai.tanvo/tanvo-mcp

Answered from the data above

Is ai.tanvo/tanvo-mcp safe to install?

We do not rate servers as safe or unsafe. 6 of its 9 applicable record checks are met (facts from public records, each listed on this page). What the records show: Its source repository opens publicly. Its repository had a push in the last 90 days. The listed version is the latest stable release. The package itself has no known vulnerability (OSV.dev). Its full dependency tree has packages with advisories (2 high; npm audit). 5 of its tools describe changing data (our AI model's reading of the descriptions). These are facts with their sources on this page, not a safety guarantee, and we did not run its tools.

Has ai.tanvo/tanvo-mcp been security tested?

Partly. 2 of the 12 checks that apply to it were exercised. We started the package in an isolated sandbox and read what it declares, but this test round was read-only, so its tools were not called. No security verdict is published before verification.

What can ai.tanvo/tanvo-mcp do?

It lists 10 tools. In our AI model's reading of their descriptions (two runs had to agree, nobody checked it by hand), they include tools that read or search, control a browser or desktop and generate content. We did not call any tool, so this describes the text, not the behaviour.

Can ai.tanvo/tanvo-mcp change or delete data?

5 of its tools say in their description that they create, edit, delete, send or run something (our AI model's reading). We did not call any tool, so we cannot say what actually happens.

Does ai.tanvo/tanvo-mcp publish a security policy?

We found no SECURITY.md in its repository (root, .github/ or docs/) or in its owner's .github repository.

Is the listed version current?

Yes. The registry lists 0.2.1, the latest stable release on npm.

Where is the source code of ai.tanvo/tanvo-mcp?

In github.com/tanvoai/tanvo-mcp, which opens publicly.

What did we test, and what did we leave out?

18 checks · features #1, #2

Not probed (read-only run)

We started the package in an isolated sandbox and read what it declares, but this test round was read-only, so its tools were not called. No security score is given; a check we did not run is never counted as passed.

It shows this server's record-check count: facts from public records, no tool called. It is not a security rating or a pass. It links here and updates after each data reload.

Something wrong, or is this yours?

If a fact here is wrong, tell us and we will re-check it. If you operate this server, you can run our checks on it yourself with the free self-test command; we call no server’s tools ourselves for anything shown here.
