What is ssh-mcp-jumpserver AGENTS.md?

Repository instructions for a TypeScript MCP server that provides SSH access and JumpServer host discovery. They explain the project layout, development commands, coding style, and available verification steps.

Use them when building, developing, checking, or adding tests to the ssh-mcp-jumpserver project.

They help a coding agent follow the repository’s conventions and avoid editing generated files or using unsupported commands.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00578	$0.00578
Opus 5.5	$0.00231	$0.00231
Sonnet 5.5	$0.00116	$0.00116

Security

Grade A, and why

ssh-mcp-jumpserver 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 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.

Repository Guidelines

Project Structure & Module Organization

This is a TypeScript MCP server for SSH access and JumpServer host discovery. Source code lives in src/: index.ts is the CLI entry point, server.ts registers MCP tools, and feature modules are grouped under config/, jumpserver/, security/, ssh/, and utils/. Example client and SSH configuration files are in examples/. Generated build output goes to dist/ and should not be edited directly.

Build, Test, and Development Commands

npm ci: install dependencies exactly from package-lock.json.
npm run build: compile TypeScript with tsc; this is the CI validation command.
npm run dev -- --project-root .: run the server from src/index.ts with tsx for local development.
npm start: run the compiled server from dist/index.js.
npm run inspect: launch the MCP inspector against the TypeScript entry point.

There is currently no dedicated test script. Use npm run build as the minimum verification step.

Coding Style & Naming Conventions

Use TypeScript ES modules and keep imports explicit with .js extensions where required by Node16 module resolution. The project uses strict TypeScript settings, ES2022 targets, and declaration/source map output. Follow the existing style: two-space indentation in JSON, concise TypeScript functions, camelCase for variables/functions, PascalCase for types/interfaces, and directory-level index.ts exports for module boundaries.

Keep files encoded as UTF-8 without BOM and use CRLF line endings.

Testing Guidelines

No test framework is configured yet. For behavior changes, add focused tests only after introducing a test runner, and document the new command in package.json and this guide. Until then, verify with npm run build and, for MCP behavior, exercise the relevant tool through npm run inspect or a local MCP client.

Commit & Pull Request Guidelines

Recent commits use Conventional Commit-style prefixes such as feat: and chore(deps):. Keep commit messages short, imperative, and scoped to one change.

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.
