corrosion-kb

corrosion-kb is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from puran-water/corrosion-engineering-mcp. Its token cost is not measured, scanned A, original, MIT.

An MCP server for searching a corrosion-engineering knowledge base, a collection of technical information about material damage caused by corrosion. It requires several local search and language-model services to run.

In plain words
What is it for?
Searching the corrosion knowledge base. The input does not specify other supported jobs.
Why use it?
It helps an agent find relevant corrosion information without searching the knowledge base manually.

MCP server for Claude CodeCodexCursorGemini CLIOpenCode

Written for no agent in particular: it speaks MCP, so any client can run it. Also seen: listed in a Claude config.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/hvksh/knowledgebase/.venv/bin/python.

One of 2 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

Good fit Searching the corrosion knowledge base. The input does not specify other supported jobs.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code, Codex, Cursor, Gemini CLI, OpenCode.

Security

Grade A, and why

corrosion-kb 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 11d 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.

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.
