feat(mcp): add GoReleaser + release workflow + MCPB bundle for cudly-mcp - #4
Conversation
…dly-mcp Ports LeanerCloud/cloud-commitments-cli#1893 into this split repo, where the MCP server now lives at the repo root and cmd/cudly-mcp is unchanged. - .goreleaser.yml: builds static (CGO_ENABLED=0) darwin/linux, amd64/arm64 binaries of ./cmd/cudly-mcp with the version ldflag, uploaded raw so the MCPB pack step can consume them directly; release.github.name now points at cloud-commitments-mcp. - .github/workflows/release.yml, on a v* tag push: consistency gate (server.json and mcpb/manifest.json versions both match the tag) -> test -> GoReleaser -> MCPB pack (full edition, all 11 tools) uploaded as an extra release asset -> mcp-publisher publish to the MCP Registry via GitHub OIDC. Carries forward the original PR's CR-driven hardening: the three publishing jobs (contents:write/id-token:write) are bound to an `environment: release`, and scratch files (the packed .mcpb, the patched server.json) live under $RUNNER_TEMP instead of the checkout root. - mcpb/manifest.json + mcpb/server/{darwin,linux}-launch.sh: the MCPB desktop-extension bundle. repository.url now points at cloud-commitments-mcp; the per-OS launch scripts are unchanged (MCPB's platform_overrides differentiate by OS only, not architecture). - .gitignore: ignore the staged per-arch binaries under mcpb/server/, packed *.mcpb files, and GoReleaser's /dist/ output. Path/reference adjustments from the monorepo version: - release.yml's test job runs `go test ./...` instead of `./mcp/... ./cmd/cudly-mcp/...` -- this repo's module *is* the MCP server now, so `./...` already covers both cmd/cudly-mcp and the rest. - .goreleaser.yml and mcpb/manifest.json point at github.com/LeanerCloud/cloud-commitments-mcp instead of github.com/LeanerCloud/CUDly. - Dropped comment references to mcp/README.md and docs/plans/mcp/05-store.md, which weren't carried over by the split. - The environment/tag-ruleset gap CodeRabbit raised on the original PR (environment:release alone isn't a reviewer gate; no v* tag ruleset exists) is still open here -- verified via `gh api repos/LeanerCloud/cloud-commitments-mcp/rulesets` (empty) and `.../environments` (empty). Re-filed as #3 (the monorepo tracked it as reserved-instances-cli#1896, which doesn't carry over). Verified locally: - `goreleaser check` -- config valid - `goreleaser release --snapshot --clean --skip=publish` -- builds all 4 binaries - `actionlint .github/workflows/release.yml` -- clean - `zizmor .github/workflows/release.yml` -- 0 findings (default persona); only informational/low findings under --persona pedantic (job naming, missing concurrency group), same as upstream - `GOWORK=off go build ./... && go vet ./...` -- clean - `GOWORK=off go test -race -short ./...` -- 338 passed, 3 packages - `npx @anthropic-ai/mcpb@2.1.2 validate mcpb/manifest.json` -- passes - `npx @anthropic-ai/mcpb@2.1.2 pack mcpb` against the real (non-snapshot) GoReleaser output -- produces a valid 95.2MB bundle - Unpacked the bundle and drove server/darwin-launch.sh through a real MCP stdio handshake: reports the injected snapshot version and lists all 11 tools correctly The release workflow cannot publish from a PR: it triggers only on `v*` tag pushes (no pull_request trigger), and no tag has been pushed by this change.

Protect release tags before enabling this workflow.
If a repository writer pushes a v* tag to an unreviewed commit, this workflow can publish that commit with contents: write and registry OIDC access. The release environment does not require approval while it has no required reviewers. Configure v* tag protection and required reviewers before the first tag push. Issue #3 tracks this gap, but the workflow does not enforce either control. (docs.github.com)

Confirmed and taken seriously -- verified via gh api repos/LeanerCloud/cloud-commitments-mcp/rulesets (empty) and .../environments (empty) that neither control exists yet. This mirrors the same finding CodeRabbit raised on the source PR (reserved-instances-cli#1893), which landed the code-side mitigation already present here: the three publishing jobs (goreleaser, mcpb, publish-registry) are bound to environment: release. The remaining work -- required reviewers on that environment, and a v* tag-protection ruleset -- is repo-admin Settings work outside what this workflow file can express, tracked here as #3 (the monorepo tracked the equivalent as reserved-instances-cli#1896, which doesn't carry over to this repo).

@cristim, thanks for confirming. Binding the publishing jobs to release prepares them for an approval gate, but it does not require approval yet. The v* tag-protection ruleset also remains absent. Issue #3 tracks both repository settings changes, so I’ll leave this finding open until they are configured.

CodeRabbit's review on #4 flagged that the manifest has no Windows binary or win32 platform_override, but MCPB treats an omitted compatibility.platforms list as "supports every platform" -- so a Windows user installing this bundle would have Claude Desktop select the Linux launcher and fail to start the server. Add `compatibility.platforms: ["darwin", "linux"]` to mcpb/manifest.json, matching the two launch scripts and the GoReleaser build matrix (both darwin/linux only). Re-validated with `npx @anthropic-ai/mcpb@2.1.2 validate mcpb/manifest.json`. Co-Authored-By: claude-flow <ruv@ruv.net>

…ency Addresses an independent review of PR #4: 1. mcp-publisher install (release.yml): `curl -L | tar xz` had no integrity check on a binary executed by a job holding id-token: write. Switched to `curl -fsSL` into $RUNNER_TEMP, verify against a sha256 pinned from upstream's own registry_1.8.1_checksums.txt (cross-checked by re-downloading and hashing the linux_amd64 asset directly, not just reading the checksums file), then additionally verify the release's Sigstore bundle with `cosign verify-blob` against the exact GitHub Actions OIDC identity that signed it (extracted from the bundle's certificate SAN: repo, workflow, and tag all pinned to v1.8.1, so a future version bump without updating this step fails loud instead of silently trusting a different signer). Runner is always ubuntu-latest, so only the linux_amd64 asset is needed. 2. Build provenance: added actions/attest-build-provenance (SHA-pinned @4d101475d8b20a2381f78447822ac1eab6504dd8, v4.2.2) over the GoReleaser binaries (dist/cudly-mcp_*/cudly-mcp) in the `goreleaser` job and over the packed .mcpb bundle in the `mcpb` job. attestations: write + id-token: write added only to those two jobs. 3. Added workflow-level `concurrency: {group: release-${{ github.ref }}, cancel-in-progress: false}` -- one release pipeline per tag at a time; never cancels a partially-published run mid-flight. 4. .goreleaser.yml's comment claimed the MCPB step reads GoReleaser's binaries straight out of dist/; corrected -- the mcpb job runs on a separate runner and actually re-fetches them via `gh release download`, as release.yml already did. 5. release.yml's test job now runs `go test -race -short ./...`, matching ci.yml instead of a plain `go test ./...`. Verified: `goreleaser check` clean; native `actionlint 1.7.12`-compatible binary clean; `zizmor --persona=pedantic --min-severity=low` clean (5 job-naming findings remain at informational severity, filtered by min-severity=low, unchanged from before); manually exercised the new sha256sum -c and cosign-identity-derivation logic and the tar extraction path against the real v1.8.1 release assets.

CodeRabbit caught that the publish-registry job's cosign verify-blob step (added in 77c9f21) assumed cosign was preinstalled on ubuntu-latest. It isn't part of the documented runner-images toolset, and this job never runs on a PR, so CI couldn't have caught the gap. Add sigstore/cosign-installer (SHA-pinned @6f9f17788090df1f26f669e9d70 d6ae9567deba6, v4.1.2) pinned to cosign-release: v3.0.6 before the verify-blob call.

The release workflow triggers only on
push: tags: ["v*"](nopull_requesttrigger), so it cannot run, let alone publish, from this PR.Ported from LeanerCloud/cloud-commitments-cli#1893 (monorepo split). That PR's two commits (the initial machinery + a CodeRabbit-driven fix for environment gating and scratch-file placement) are squashed into one commit here, since both apply together in the split repo.

mcp/prefix (release tooling lived at the monorepo root already), so the port is mostly a path/reference rewrite plus dropping stale doc citations, not a directory move.Outstanding review item carried forward
CodeRabbit's review on #1893 flagged that
environment: releasealone is not an approval gate until reviewers are configured, and that nothing restricts who can push av*tag. The original PR's fix commit added theenvironment: releasebinding (carried forward here) and filed reserved-instances-cli#1896 to track the two repo-admin actions (required reviewers on the environment, av*tag-protection ruleset) needed to make it a real gate. That issue doesn't carry over to this repo, so I re-verified the current state here (gh api repos/LeanerCloud/cloud-commitments-mcp/rulesetsand.../environmentsboth return empty) and re-filed it as #3.Hardening follow-up (independent review)
An independent review of this PR (head 2c6f787) flagged 5 findings, addressed in 77c9f21 -- see the PR comment for the per-finding detail:
