Release Notes Index MCP server

• Registry namesh.releases/mcpverified in the MCP registry

The registry name sits under releases.sh. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 568 ms.

• Whether its tools do the product's job has not been judged yet.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• search

  Unified search across the registry and release content. Returns up to four sections — organizations, catalog entries (products + standalone sources folded into one list), curated collections (cross-org playlists), and releases with…

• get_latest_releases

  Get the most recent releases, optionally filtered by product or organization. Excludes prereleases (canaries / alphas / betas / RCs) by default — pass `include_prereleases: true` to include them. Cursor-paginated: pass `limit` for slice…

• list_catalog

  List catalog entries — products and standalone sources combined into one list with an `entryType: 'product' | 'source'` discriminator per row. Orgs that group multiple sources under a product (e.g. Vercel → Next.js, Turborepo) surface…

• get_catalog_entry

  Detail for a single catalog entry — accepts a prod_ id, src_ id, or an org-scoped coordinate in the form orgSlug/slug (e.g. 'vercel/nextjs' or 'vercel/next-js'). Returns the union of product / source detail fields depending on the entry…

• list_organizations

  List all indexed organizations, optionally filtered. Paginated: defaults to 50 entries per page; pass `page: 2` for the next slice. Orgs with zero indexed releases are hidden by default (curator-stub noise); set `include_empty: true` to…

• get_organization

  Get detailed information about a single organization — accounts, tags, sources, products, aliases. When an AI-generated overview exists the response includes a short preview; pass `include_overview: true` to inline the full briefing (with…

• lookup_domain

  Resolve a domain to the org or product that owns it. The domain is normalized first (scheme, `www.`, path, and trailing slash stripped, lowercased), so `https://vercel.com/about` and `vercel.com` both look up the same row. Returns the…

• list_collections

  List curated collections — named cross-org playlists (e.g. 'Frontier AI Labs') independent of the fixed category taxonomy. Use `get_collection` for a collection's full member list, or `get_collection_releases` for the interleaved…

• get_collection

  Detail for a single collection — name, description, and the ordered list of member organizations. Hidden / on-demand orgs never leak through; only publicly visible orgs appear in the member list.

• get_collection_releases

  Interleaved cross-org release feed for a collection — same shape as `get_latest_releases` but scoped to the collection's member orgs. Cursor-paginated: pass `limit` for slice size (default 20), `cursor` to continue from a prior call. The…

• get_release

  Fetch the full content of a single release by id. Release ids are returned by search or get_latest_releases — pass them here to read the whole entry (e.g. to quote a specific Next.js release note). Accepts the full rel_<nanoid> form or…

• follow

  Follow an organization or a product so it appears in your personalized feed (`get_personalized_feed`). Following an organization implicitly includes all of its products. Requires a signed-in user (a `relu_` user key or an OAuth token)…

• unfollow

  Stop following an organization or product. Requires a signed-in user. `entity` is an `org_…` or `prod_…` id. Idempotent: unfollowing something you don't follow is a no-op.

• list_follows

  List the organizations and products you follow (newest first). Requires a signed-in user.

• get_personalized_feed

  Your personalized release feed — recent releases from the organizations and products you follow, newest first. Requires a signed-in user. Same item shape as `get_latest_releases`, scoped to your follows. Each item prints `URL:` (the…

• list_webhooks

  List your outbound release webhooks, personal or workspace. Requires a signed-in user (a `relu_` user key or an OAuth token). With no `workspace`, lists your personal webhooks (`GET /v1/me/webhooks`) and includes a short list of your…

• manage_webhook

  Create, update, delete, test, or rotate the signing key of an outbound release webhook — personal or workspace. Requires a signed-in user. This tool sends requests to an external URL you supply and can delete or disable delivery, so treat…

• whats_changed

  Given a package and a `from`/`to` version, return the changelog entries between them — `(from, to]`, from exclusive, to inclusive — with summaries and breaking-change verdicts. One call instead of reading N changelog pages to plan an…
