Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00879 | $0.00879 |
| Opus 5 | $0.00439 | $0.00439 |
| Sonnet 5 | $0.00176 | $0.00176 |
| Haiku 4.5 | $0.00088 | $0.00088 |
Grade A, and why
ssh-mcp-jumpserver CLAUDE.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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Build & Development Commands
npm run build # TypeScript compile (tsc)
npm run dev # Hot-reload dev mode (tsx src/index.ts)
npm start # Run compiled output (node dist/index.js)
npm run inspect # Debug with MCP Inspector
- TypeScript: strict mode, ES2022 target, Node16 module resolution
- No tests, no linter, no formatter — CI only verifies
tsccompiles successfully - All source files use
.tsextensions with.jsimport extensions (ESM style)
Install as Global CLI (recommended)
npm run build
npm link # or: npm install -g .
# Now you can run from anywhere:
ssh-mcp-jumpserver --jumpserver-url https://jump.example.com ...
Project Architecture
An MCP server that bridges AI agents to remote servers via SSH, with JumpServer dynamic host discovery. Launched as a subprocess by MCP clients (Claude Desktop, VS Code, etc.), communicating over stdin/stdout via JSON-RPC.

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.

ssh-mcp-jumpserver CLAUDE.md is an instructions file published in the GitHub repository helloNice/ssh-mcp-jumpserver (0 stars, last pushed 28d ago), licensed MIT. It adds 879 tokens to every session, about $0.0044 per session on Opus 5. A static security scan graded it A with 0 findings.
