An MCP server that gives AI agents access to the kotlin-lib tools. MCP, or Model Context Protocol, is a standard way for an AI agent to call external tools.

Use it to connect an AI coding agent to the kotlin-lib service through Docker and answer questions about published JVM libraries.

It lets an agent inspect real Kotlin and Java library sources without building those inspection tools into the agent itself.

kotlin-lib — MCP server for Claude Code by aoreshkov

Install

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.

Clone the repo

git clone --depth 1 https://github.com/aoreshkov/kotlin-lib-mcp

Made for: Claude Code.

Or install kotlin-lib, the plugin that ships this one along with the rest of its 4 skills, 1 MCP server.

Security

Grade A, and why

kotlin-lib 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 8d 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.

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.
