v1.0.1

Packaging-metadata point release. No code or behavior changes.

Added

• Added [project.urls] packaging metadata (Homepage / Repository / Documentation /
  Changelog / Issues) so the PyPI page links back to the canonical repo and docs.
  The published 1.0.0 page carried no project URLs; for a supply-chain tool that must
  be distinguishable from the unrelated mcp-warden PyPI package, the back-links to
  the canonical GitHub repo and docs site are part of the trust surface.

v1.0.0

First stable release. No new core features over 0.3.0 — v1 is the
distribution-hygiene, self-credentialing, and documentation hardening of an already
v1-strong foundation. Highlights of the 0.3.0 → 1.0.0 arc:

Added

• Sigstore keyless signing + verification of warden.lock via pin --sign and
  check --verify (opt-in mcp-warden-cli[sigstore] extra). The tool now signs its own
  release artifacts, not just others' locks. (#16)
• Deterministic structural JSON-Schema diffing for tool inputSchema changes:
  each security-relevant mutation (required dropped, enum widened/removed, type
  broadened, constraint relaxed, additionalProperties opened) is classified
  per-fact as WRD-DRIFT-SCHEMA-* instead of one opaque change. (#15)
• In-document $ref resolution in the schema differ, so $ref targets are diffed
  structurally instead of reported as an opaque leaf. (#29)
• Official composite GitHub Action wrapping mcp-warden check with SARIF upload to
  code scanning; all runtime deps hash-locked in action/requirements.lock. (#18)
• pre-commit hook (mcp-warden-check) running the identical drift verdict locally,
  with a --strict fail-closed mode and a pre-push variant. (#22)
• --strict fail-closed mode for the guard proxy: an internal inspection error
  terminates the session (exit 3, -32003) instead of failing open. (#21)
• warden diff: offline, redacted, human-readable comparison of two locks over the
  drift engine — never re-captures, never prints raw server.command/args. (#20)
• Structured provenance metadata + warden lock rotate: re-attest a baseline's
  provenance without re-capturing the surface (overall_digest stays byte-identical).
  (#19)
• Property-based fuzzing (Hypothesis) of the guard stdio framer, ANSI stripper,
  exfil-domain matcher, and secret redactor under tests/fuzz/. (#17)
• --strict-frame-cap: fail-closed on over-cap server→client result frames. (#37)
• Raw-IP-literal exfil/SSRF matching (D6): deterministic matching of exfil-domain
  rules against raw IPv4/IPv6 literal hosts, closing the IP-literal bypass of the
  domain matcher. (#54)
• guard startup posture banner reporting the active enforcement stance
  (active / monitor / inactive, derived from the live BLOCK_RULES), plus a
  fail-closed refusal (exit 2) on non-POSIX / degraded platforms unless explicitly
  overridden. (#57)
• Vendor-neutral MCP Lock Format v1 spec (docs/SPEC.md) and an education-first
  docs site with an honest comparison page. (#46, #47, #48, #50)
• MCP Lock Format v1 compatibility & versioning policy (docs/SPEC.md §14) plus a
  THREAT_MODEL.md §5.3 self-bypass section (signed-lock replay, SARIF suppression,
  JCS canonicalization edge cases). (#56)
• Hash-pinned dev/CI lockfile (requirements-dev.lock) and a documented
  dependency-update policy in SECURITY.md, so the toolchain that builds a
  supply-chain gate is itself pinned. (#59, closes #14)
• Release-on-publish GitHub workflow with OIDC trusted publishing to PyPI and
  self Sigstore signing of the release artifacts, plus a RELEASING.md runbook. (#58)

Changed

• Distribution name mcp-warden-cli. The PyPI distribution name is mcp-warden-cli
  because mcp-warden is taken on PyPI by an unrelated package, and PyPI rejects
  mcpwarden as "too similar" to it (separator-stripping collapses both to the same
  string). mcp-warden-cli normalizes to letters-only mcpwardencli, which is
  distinct. The CLI command (mcp-warden) and repo are unchanged. (#55)
• README repositioned around the lockfile / CI-gate category claim, with the
  stdio-transport scope surfaced in the opening paragraph and a "Who it's for"
  use-cases section (author-flagship first). (#45, #49, #55)

Fixed

• redact_secret never discloses more than half of a detected secret. (#38)
• Removed the install hazard: every pip install mcp-warden snippet (README, docs
  site, example workflows) now installs mcp-warden-cli. The README carries a prominent
  impostor-warning banner. (#55)
• Corrected the SPEC.md worked-example schema_version from 1 to 3 to match the
  live SCHEMA_VERSION. (#56)

Security

• The release pipeline signs its own artifacts (Sigstore / attestation) and publishes a
  pinned-hash lockfile for the install path — the "heal thyself" requirement for a
  supply-chain tool. (#58, #59)
