cut-copy-paste-mcp: Instructions file for Codex

AGENTS.md

cut-copy-paste-mcp AGENTS.md is an instructions file for Codex, OpenCode from Pr0j3c7t0dd-Ltd/cut-copy-paste-mcp. It costs 524 tokens per session, scanned A, original, MIT.

A local MCP server that provides cut, copy, paste, and undo operations to AI coding agents. MCP is a way for assistants to use connected tools and services.

In plain words
What is it for?
Use it when an AI coding agent needs to cut, copy, paste, or undo content during coding work.
Why use it?
It gives the coding agent operations for changing and undoing text or code without requiring a separate application.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is Pr0j3c7t0dd-Ltd/cut-copy-paste-mcp's own configuration. It tells Codex and OpenCode how to work on cut-copy-paste-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cut-copy-paste-mcp configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

cut-copy-paste-mcp AGENTS.md 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 9d 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.

Repository Guidelines

Project Structure & Module Organization

  • src/lib holds core services (DatabaseManager, ClipboardManager, SessionManager, OperationLogger, FileHandler) that implement cut/copy/paste state and persistence.
  • src/tools exports ClipboardTools bridging the library to MCP agents; keep orchestrations there.
  • Tests live beside code in __tests__ folders; mimic directory layout when adding new specs.
  • Built artifacts emit to dist/ via tsc; never check the folder in.

Build, Test, and Development Commands

  • npm run build -> TypeScript compile to ES modules in dist/.
  • npm test -> Jest suite with ESM support; runs fast unit tests.
  • npm run test:watch -> Jest watch mode for iterative work.
  • npm run test:coverage -> Enforces 80% global thresholds defined in jest.config.js.
  • npm run lint / npm run format -> ESLint + Prettier; always lint before pushing.

Coding Style & Naming Conventions

  • TypeScript strict mode; prefer explicit return types on exported functions to satisfy lint warnings.
  • Use ES module imports with .js extension when targeting compiled output (see existing files).
  • Files and directories use kebab-case; classes PascalCase; functions and variables camelCase.
  • Prettier enforces 2-space indent, 100-character width, semicolons, and single quotes; do not hand-edit formatting.

Testing Guidelines

  • Write Jest specs in __tests__ folders or *.test.ts; mirror source structure for discoverability.
  • Mock filesystem/database boundaries sparingly; prefer exercising ClipboardManager + DatabaseManager together to maintain undo coverage.
  • Keep coverage >=80%; run npm run test:coverage before PRs and include rationale if lower.

Commit & Pull Request Guidelines

  • Craft commit subjects in imperative voice (Add session timeout guard); keep summaries <=72 characters.
  • Reference scope in the body when touching multiple modules (lib: or tools: tags help).
  • PRs should describe behavior changes, list test commands run, and link issues or TODO items when relevant; include CLI output snippets only when they illustrate behavior.

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.
