Worth knowing before you connect it

  • The registry marks this server deprecated.
  • The listed package does not exist on PyPI, so an install from the registry entry fails.
  • The linked repository does not open publicly, so the code cannot be reviewed through it.

Each line comes from a section below, with its source and date.

  • Arguments are written as the registry entry gives them; a named one as “--name value”, the form the registry documentation shows.
  • Optional settings the entry also lists (left out above): NEBIUS_API_KEY, OPENROUTER_API_KEY.
  • This runs the publisher's code on your machine (uvx). 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.

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.lambdabypi/leangate

Answered from the data above

Is io.github.lambdabypi/leangate safe to install?

We do not rate servers as safe or unsafe. 0 of its 3 applicable record checks are met (facts from public records, each listed on this page). What the records show: The repository it links to does not open publicly, so its code cannot be inspected through that link. Its registry entry is marked deprecated. The listed version cannot be installed today. The package itself has no known vulnerability (OSV.dev). These are facts with their sources on this page, not a safety guarantee, and we did not run its tools.

Has io.github.lambdabypi/leangate been security tested?

We tried, but no check could run. None of the 18 checks that apply to it could be exercised. No session could be opened when we tried, so no check could run. No security verdict is published before verification.

Is the listed version current?

The listed version cannot be installed: package does not exist.

Where is the source code of io.github.lambdabypi/leangate?

The registry links to github.com/lambdabypi/leangate, but that link does not open publicly, so the code cannot be inspected through it.

Security testing

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

18 checks · features #1, #2

No session

No session could be opened when we tried, so no check could run. No security score is given; a check we did not run is never counted as passed.

Why not security-tested: The package's process closed before a session opened, and the recorded output does not show whether the cause was ours or the package's. — cause not determined
