Release instructions for publishing packages from the @mcp-b monorepo, a repository that contains multiple related packages. It uses changesets to record package updates and generate changelog entries.

It guides validation, changeset creation, version releases, authentication, package builds, and publishing with pnpm.

It helps prevent incomplete releases, incorrect dependency order, missing changelog records, and publishing unverified code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00045	$0.01403
Opus 5.5	$0.00018	$0.00561
Sonnet 5.5	$0.00009	$0.00281
Haiku 4.5	$0.00005	$0.00140

Security

Grade A, and why

release scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Release @mcp-b packages

Use the existing Release workflow. CI publishes from main using npm OIDC, not an NPM_TOKEN secret. Do not publish, dispatch, push, or change remote settings without authorization.

Stable releases

Validate the changes:

pnpm build && pnpm typecheck && vp check && pnpm test:unit && pnpm release:check

Run pnpm changeset. Select only packages with actual changes and describe the consumer-facing effect. Separate summaries when packages need different release notes.
Commit the changeset with the implementation and submit the PR.
After merge, CI creates or updates chore(release): version packages.
Review that PR's versions, changelogs, relay manifest and global CDN test pin. Merging it lets CI publish the release.

The version PR uses GITHUB_TOKEN. GitHub can hold workflows from bot-created or updated PRs for approval: a maintainer with write access selects Approve workflows to run in the PR merge box, then waits for all required checks. Do not bypass checks or add a PAT to work around an approval prompt. See GitHub's workflow trigger rules.

Never hand-edit package versions or use pnpm version: this bypasses changelogs and fixed-group coordination. All 12 published packages belong to one Changesets fixed group; private workspace apps and examples are not released.

pnpm changeset:version applies versions and synchronizes checked-in metadata through scripts/release-metadata.mjs --write. Normally the workflow runs it. Use it locally only when preparing an explicitly requested version commit.

ci:publish validates metadata, publishes unpublished package versions in dependency order, then runs changeset tag. The pinned Changesets action reads those new-tag messages to create GitHub releases and trigger SBOM, MCPB and signing steps. Keep the tag command after a successful publish; plain pnpm publish does not emit Changesets release events.

What ships with it

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

release is a skill published in the GitHub repository WebMCP-org/npm-packages (106 stars, last pushed 2d ago), licensed MIT. It adds 45 tokens to every session and 1,403 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
