Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00057 | $0.01163 |
| Opus 5 | $0.00028 | $0.00581 |
| Sonnet 5 | $0.00011 | $0.00233 |
| Haiku 4.5 | $0.00006 | $0.00116 |
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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cut a release
The release workflow (.github/workflows/release.yml) is triggered by a v* tag and its
first step is a hard version-match guard: if the tag doesn't match the version in both
source-of-truth files, the whole release (GitHub release + GHCR image + MCP registry
publish) fails. This skill makes the two files agree before the tag is pushed.
The advertised MCP
Implementationversion is not a third file to bump: it is build-derived fromgradle.properties(server/build.gradle.ktsbakesproject.versioninto a resource read byServerVersion) and asserted byServerVersionTest, so it can never drift and needs no separate guard.
1. Determine the new version
Use $ARGUMENTS if given. Otherwise read the current version from gradle.properties
(version=), decide the bump with the user (semver), and confirm. Call the new value
<VERSION> (no v prefix inside files; the git tag is v<VERSION>).
2. Bump the version in BOTH guarded files
The tag guard checks these exact patterns (keep the formatting identical):
gradle.properties— the lineversion=<VERSION>(guard:^version=<VERSION>$). This is the single source of truth; the runtime MCP version is derived from it (see the note above), so there is no third file to bump.server.json— the top-level"version": "<VERSION>"(guard:jq .version == <VERSION>). Note: the workflow later also rewritesserver.json.versionand.packages[0].identifierfrom the tag, but the guard still requires the committed value to match, so set it here.
Miss either and the release job aborts at the guard step. Grep to confirm both:
grep -n "version=" gradle.properties
grep -n '"version"' server.json
On a MAJOR or MINOR bump, also repin the plugin. plugin/.mcp.json pins the image to the
<major>.<minor> tag (ghcr.io/aoreshkov/kotlin-lib-mcp:0.5), which follows patches on its own
but not a minor bump. Update that tag and bump plugin/.claude-plugin/plugin.json .version
(its own semver, independent of the server's) so installed plugins actually receive the update —
the community catalog re-pins from the repo automatically. Patch releases need neither.
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 aoreshkov/kotlin-lib-mcp (8 stars, last pushed yesterday), licensed Apache-2.0. It adds 57 tokens to every session and 1,163 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
