klanex

klanex is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from chrassy/klanex-mcp. Its token cost is not measured, scanned A, original, MIT.

A local service for running agent tool calls asynchronously, with checks for valid inputs, retries, duplicate-prevention, and an audit trail.

In plain words

What is it for?: Use it when agent workflows need reliable background tool execution, retry handling, duplicate protection, and a record of what happened.
Why use it?: It helps make tool calls easier to track and less likely to fail silently or run the same action more than once.

Written for no agent in particular: it speaks MCP, so any client can run it.

Good fit Use it when agent workflows need reliable background tool execution, retry handling, duplicate protection, and a record of what happened.

Security

Grade A, and why

klanex 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 2mo 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.
