Claude Code

claude mcp add --env "MUTAGEN_API_KEY=<MUTAGEN_API_KEY>" --transport stdio mutagen-ru-mcp -- npx -y mutagen-ru-mcp@0.1.0

Try it in the MCP Inspector · runs on your machine, opens in your browser · Node 22.19+

npx @modelcontextprotocol/inspector@2.11.0 -e "MUTAGEN_API_KEY=<MUTAGEN_API_KEY>" -- npx -y mutagen-ru-mcp@0.1.0

Replace <MUTAGEN_API_KEY> with your own values; the entry marks MUTAGEN_API_KEY as secret, so keep the file out of version control.
Optional settings the entry also lists (left out above): MUTAGEN_BUDGET_RUB, MUTAGEN_AUTO_APPROVE_RUB, MUTAGEN_FREE_ONLY, MUTAGEN_TOOLS.
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.

Does the registry listing match what we found?

Feature #6

The registry verifies a package once, when it is published, and does not re-check it. A difference below is about the listing, not a judgement of the publisher.

Registry says	We found	Result	Source · date
Version 0.1.0 on npm	Exists and can be installed	matches	npm · 2026-10-23

Read from public records only: the registry entry, npm/PyPI, GitHub and advisory databases, checked 2026-10-23. No tool was called. Only “met” and “not met” are counted, so the total differs between servers; a check that does not apply or that we could not run is listed, never counted against it. It is not a safety rating.

Common questions about io.github.SVorobiev-ru/mutagen-ru-mcp

Answered from the data above

Is io.github.SVorobiev-ru/mutagen-ru-mcp safe to install?

We do not rate servers as safe or unsafe. 8 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 no known advisory. These are facts with their sources on this page, not a safety guarantee, and we did not run its tools.

Has io.github.SVorobiev-ru/mutagen-ru-mcp been security tested?

Not yet. It requires a credential (a key or token) that the publisher marks as required. We never fill in credentials, so we did not start it.

Does io.github.SVorobiev-ru/mutagen-ru-mcp publish a security policy?

Yes: its repository has a public security policy (github.com/svorobiev-ru/mutagen-ru-mcp/blob/HEAD/SECURITY.md). That is the publisher's statement, not permission for us to test the server, and we call none of its tools.

Is the listed version current?

Yes. The registry lists 0.1.0, the latest stable release on npm.

Where is the source code of io.github.SVorobiev-ru/mutagen-ru-mcp?

In github.com/SVorobiev-ru/mutagen-ru-mcp, which opens publicly.
