Ratatosk reads CNCF release notes every hour. Your agents get the changes.
English · 한국어 · 日本語
In Norse myth, Ratatoskr is the squirrel that carries messages up and down the world tree. This one carries release intelligence. ratatosk.io watches 76 CNCF projects and turns every release note into typed, entity-level changes: security fixes, breaking changes, removals, deprecations, changed defaults — each one classified by how you should act on it now. Routine lines are recorded too, but kept out of the way.
This repository is the MCP server that hands those changes to your agent as tools. MCP (Model Context Protocol) is the open standard AI agents use to call external tools; any MCP-capable client — Claude Code, Claude Desktop, kagent, your own SDK agent — can connect. No account, no API key.
Hosted — nothing to install. Register https://ratatosk.io/mcp as a remote MCP server in any client that supports remote connectors. The hosted endpoint allows each caller 60 tool calls a minute, counted per caller rather than pooled — for polling or CI workloads, self-host. With the Claude Code CLI:
claude mcp add --transport http ratatosk https://ratatosk.io/mcp
Self-hosted — the same server, running as your own process. Run it with Docker, the Helm chart, or a source build. With Claude Code and Docker installed:
claude mcp add ratatosk -- docker run -i --rm ghcr.io/basphere/ratatosk-mcp:0.10.0
0.10.0 is the current release; use latest to follow new ones.
Either way, verify the connection:
claude mcp list
Then ask your agent a question the tools can answer:
You: "We run envoy v1.36.8 and istio 1.30.1. Anything we must do before upgrading?"
Your agent calls
check_stackand answers from the record: the CVEs
fixed after your version, the APIs removed on your upgrade path, the defaults
that changed — separated into what applies to everyone and what applies only
if your configuration matches. Each change carries a verbatim quote from the
release notes as evidence.
One entry from a real check_stack answer, as the agent receives it (istio, measured 2026-08-20):
{
"severity": "high", "family": "security", "bucket": "action", "applies_if": "uses JWKS Resolver", "quote": "- CVE-2026-31837 / GHSA-v75c-crr9-733c : (CVSS score 8.7, High): JWKS Resolver Failure May Allow Authentication Bypass Using Known Default Keys.", "same_matter_also_addressed_in": ["1.28.5", "1.29.1"] }
applies_if is a condition the agent evaluates, not prose to read: a stack that runs no JWKS resolver skips this entry without asking anyone. The answer also carries its own privacy line, verbatim: *"versions were compared locally; only project slugs were sent to the server."*
Other clients (Claude Desktop, kagent, in-cluster agents) and the full setup reference: see the install guide.
Two things the tools speak in. A change is one thing a release did, taken from an official release note and tied to the exact identifiers it touches (a CVE id, a flag, a CRD, a config field), with a verbatim quote as evidence. Every change carries three axes:
security, breaking, or deprecated: what kind of thing it is.action (applies to everyone), check (only if applies_if matches your setup), plan (announced for later), other (the full record).A matter is the issue underneath, identified by matter_key and stable across releases and branches: the same security roll-up landing on five branches shares one key. Severity lives on the cited advisories and is read from the ledger's current value, not frozen at analysis time.
| Tool | What it does |
|---|---|
check_stack | Takes the component versions you run and returns the changes on your upgrade path, split by bucket: action_required applies to everyone, check_config only if its applies_if holds. The comparison happens inside the server process — which is your own process when you self-host (how your component versions are handled) |
list_changes | The incremental change feed, oldest-analyzed first. Filter by project, family, or bucket; page with the since cursor to keep a local copy in sync |
changes_by_entity | Reverse lookup: every change touching one exact identifier — such as a CVE id, CRD, feature gate, flag, config field, or dependency |
get_matter | Every release in which one matter appeared. The same roll-up lands on several branches carrying different advisories — told only the newest, you would assume you were covered |
get_release | One release in full: its changes, a summary, and the link to the original note. A release with zero changes means it was read and found routine |
list_releases | The newest releases of one project as one-line summaries (dates, counts by bucket and family, highest advisory severity), newest first — the tool for "what changed in X lately" |
list_projects | The roster of tracked projects and their canonical slugs (the short project id every other tool takes) — look names up here instead of guessing |
Full per-tool parameters, example calls, and measured responses live in the tools reference.
Self-hosted: check_stack sends only project slugs to the server and compares versions locally, inside this process — the versions you pass it never reach ratatosk.io. The server publishes changes; your agent decides what applies. The version normalizer is bundled (internal/version), so range comparison happens client-side too. This holds for upgrade questions as well: the upstream API has a convenience endpoint (/v1/upgrade/{project}) that receives caller-supplied versions — check_stack does not call it; the comparison is in the source you can read.
One limit on that guarantee: it covers check_stack. Tools that take a version as an argument — get_release(project, version) — put that version in the upstream request path, because fetching a specific release means naming it. That named path is not kept on my side, though: before a log line is written, query strings are stripped and /v1/releases/… and /v1/upgrade/… paths are reduced to their prefix, so neither the slug nor the version lands in a log.
Hosted: your check_stack arguments (the versions you run) pass through the server's memory to produce the same answer, and are not written down. Here is what each layer on the way keeps:
traceparent, and that line carries a normalized endpoint label and the trace id — never a path, query, or body./v1/releases/… and /v1/upgrade/… paths to their prefix, masks caller IPs, and has no field for request bodies.The hosted endpoint runs with its audit stream off, and I keep it off — not recording request content is the operating stance for that endpoint. One boundary I do not control: connection metadata on the CDN leg follows the CDN provider's own policy. If your requirements rule out that transit, self-host: then only project slugs leave your infrastructure on a check_stack call.
Self-hosting adds the opposite capability: an opt-in audit stream (MCP_AUDIT=metadata or full) that records who called which tool, emitted inside your own infrastructure into your own collectors. The hosted endpoint has none by design. Details in the install guide.
This server is a thin client over the public REST API. If you would rather call it directly, GET /v1 on ratatosk.io describes itself. No API key; rate limited at 1200 requests per minute per IP.
The data is served free of charge by ratatosk.io — a term that may change, with advance notice — under its terms of service. Analyses are AI-generated reference information with no warranty — check the original release notes before acting, especially when an agent acts on your behalf. Original notes belong to their respective projects; responses that carry a full note include an attribution notice (raw_notes_notice).
