compactprompt

compactprompt is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from gtkcyber/compact_prompt. Its token cost is not measured, scanned A, original, MIT.

A local tool for compressing prompts and other data before sending them through large language model workflows. It runs from the compactprompt Python package.

In plain words
What is it for?
Use it to prepare shorter prompt or data inputs for LLM-based tasks while retaining the information needed by the workflow.
Why use it?
It can reduce the amount of text an LLM workflow needs to process when prompts or data are too large.

Security

Grade A, and why

compactprompt 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 5d 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.
