Releases

The latest product releases, indexed for agents.

A registry of release notes from across the web — pulled from vendor changelogs, normalized into one schema, summarized, and queryable from your terminal, your code, or any MCP client. Readable by you and your agent.

_{This repo is the backend for releases.sh (API · MCP · web · ingest). The user-facing command-line tool lives in its own repo → buildinternet/releases-cli.}

What is this?

"What changed?" is a question agents and developers ask constantly — before an upgrade, after an incident, when a tool suddenly behaves differently. The answer is scattered across GitHub releases, RSS feeds, changelog pages, and blog posts in a hundred different formats.

Releases collects those into one registry. It watches hundreds of sources across the vendors developers actually depend on, and for every release stores the original content plus an AI-generated title, summary, and breaking-change classification. Each organization gets a maintained overview of what it shipped recently. The web page a human reads and the JSON an agent fetches are the same content.

This repo is the source of the canonical deployment at releases.sh: the API worker (the authoritative data plane), the MCP server, the web frontend, and the ingest pipeline + agent harness that keep the registry fresh. The user-facing CLI ships separately from buildinternet/releases-cli (npm + Homebrew).

Use it

No account or API key needed for reads — all four surfaces are public.

MCP — hosted at mcp.releases.sh, listed in the MCP Registry as sh.releases/mcp:

claude mcp add --transport http releases https://mcp.releases.sh/mcp   # Claude Code
codex mcp add releases --url https://mcp.releases.sh/mcp               # Codex
npx -y mcp-remote https://mcp.releases.sh/mcp                          # stdio bridge (VS Code, Zed, …)

CLI — one-off via npx, or brew install buildinternet/tap/releases:

npx @buildinternet/releases get anthropic     # what did Anthropic ship lately?
npx @buildinternet/releases search "MCP"      # search across every vendor

REST API — public GET endpoints on api.releases.sh, spec at /v1/openapi.json:

curl "https://api.releases.sh/v1/releases/latest?limit=5"

Agent skills — auto-triggering playbooks, installable into any agent (Claude Code / Codex / Cursor / OpenCode) without checking out anything. Start with the reader skills — search, MCP lookups, and release analysis — which is what almost everyone wants:

npx skills add buildinternet/releases-cli   # reader skills — search, MCP, release analysis

# just the skill that writes a releases.json manifest for your own product
npx skills add buildinternet/releases --skill creating-releases-json

On Claude Code, the CLI repo also installs as a plugin — the reader skills plus a bundled MCP connection and a /releases command:

/plugin marketplace add buildinternet/releases-cli
/plugin install releases@releases

_{Running or maintaining the registry itself? This repo also ships operator skills (source onboarding, parsing, bulk maintenance) — most need an admin key: npx skills add buildinternet/releases. See releases.sh/docs/skills.}

Docs — user-facing documentation is served from the web app at releases.sh/docs (source in web/src/content/docs/): installation · skills · REST API · MCP · webhooks · listing your product.

Agents consuming the product start from releases.sh/llms.txt; the MCP tool catalog and auth model are also covered in docs/architecture/mcp.md. Creating a free account unlocks higher rate limits (mint an API key at releases.sh/account), plus follows, personalized feeds, webhooks, and email digests.

_{Every org page carries an AI-maintained overview and exports as JSON, Markdown, or Atom.}

What's in this repo

How it fits together:

• Storage — Cloudflare D1 (FTS5 + Vectorize). The API worker is the sole data plane.
• Ingest — adapters for GitHub Releases, RSS/Atom/JSON feeds, and a browser-rendering fallback for feed-less pages (packages/adapters/). The crawler signs outbound fetches (RFC 9421) as a Cloudflare Verified Bot.
• AI — changelog parsing, summarization, grouping, and org overviews run in the API worker as direct Anthropic SDK calls.
• Agents — discovery + worker run as Anthropic-hosted managed agents; definitions auto-deploy on merge when their source changes.

Contributor mental model

This repo has four kinds of code:

For normal contributions, start with bun run bootstrap, bun run check, and bun test. You do not need production Cloudflare, Anthropic, Vercel, email, or Firecrawl access to work on the core loop. If you are trying to fork or self-host the full service, read deploy-coupling.md.
