fb1b0cb41c`SECURITY.md` existed on the pre-swap `main` (ac3c1a12) and still exists on
`v1/main`, but the v2 tree never had one — so #1817 silently removed the
security policy from the default branch.
That is the wrong file to be missing right now: it is where private
vulnerability reporting is advertised, and it disappeared in the same window as
2.0.0 shipping and external pull requests being turned off (#1820). Losing the
PR path and the security-report path together would leave an outside reporter
with no documented route at all.
Restored from `v1/main` with the additions #1820 asks for:
- A supported-versions table covering all four package names — v2 supported, the
v1 line security-fixes-only under the `v1-latest` dist-tag, anything below
1.0.0 unsupported. The three sub-packages are named explicitly since they
exist only on v1 and are deprecated.
- A note that the repository does not accept outside pull requests, but that
this explicitly does NOT apply to security reports, which must go through the
advisory process rather than any public channel. Without that, the new
issues-only policy reads as "no way to reach us".
- "Whether it affects v2, v1, or both" added to the report checklist, now that
two lines are live.
Verified private vulnerability reporting is enabled on the repo, so the advisory
link is a working route rather than an aspiration.

v2 ships as a single package — @modelcontextprotocol/inspector. The three
inspector-client / inspector-server / inspector-cli sub-packages exist only
on the v1 line and are deprecated.
v1 development happens on the v1/main branch and is limited to security fixes.
Those releases are published under the v1-latest dist-tag so they never
displace the current v2 release:
npm i @modelcontextprotocol/inspector@v1-latest
Everything else — features, bug fixes, improvements — lands in v2 only.
Reporting Security Issues
If you discover a security vulnerability in this repository, please report it through the GitHub Security Advisory process for this repository. Private vulnerability reporting is enabled, so this is the fastest route to a maintainer.
Please do not report security vulnerabilities through public GitHub issues, discussions, or pull requests.
Note that this repository does not accept pull requests from outside contributors (see CONTRIBUTORS.md) — this does not apply to security reports, which should always go through the advisory process above rather than any public channel.
What to Include
To help us triage and respond quickly, please include:
- A description of the vulnerability
- Steps to reproduce the issue
- The potential impact
- Whether it affects v2, v1, or both
- Any suggested fixes (optional)
