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 | $0.00426 | $0.00426 |
| Opus 5 | $0.00213 | $0.00213 |
| Sonnet 5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
junos-mcp-server 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 4d 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 it actually says
CLAUDE.md
Read-only JUNOS troubleshooting MCP server.
Invariant (do not break)
Read-only only. NEVER add a configuration/write tool. Every device command goes
through validate_show_command(), which allows only show commands and blocks
| save / | append / | tee / | load.
Layout
src/junos_mcp_server/server.py— the whole server:Settings(pydantic-settingsBaseSettings, env vars viavalidation_alias) +settings(),fetch_targets()(cached), theShowCommandpydantic model +validate_show_command(),run_show()(PyEZ), and FastMCP toolslist_devices/run_show_command.tests/test_server.py— parametrized unit tests for the command validator, target parsing, and tool dispatch. (Settings is plain pydantic — not retested.)
Targets source
GET {ORCHESTRATOR_URL}/api/surf/subscriptions/gnmi/targets (Basic Auth). The
address field is fqdn:32767 (gNMI port) — we use the FQDN only and connect
NETCONF on JUNOS_SSH_PORT (830).
Dev mode: JUNOS_DEV_MODE=1 + JUNOS_DEV_TARGETS (JSON list of node hostnames)
makes fetch_targets() return {node: node} and skip the orchestrator. A
model_validator enforces the mode rules: dev needs non-empty JUNOS_DEV_TARGETS;
prod needs ORCHESTRATOR_URL + GNMIC_HTTP_BASIC_*. SSH creds required in both.
Test
uv run --extra dev pytest -v
Style
Prefer comprehensions / itertools / next(..., None) over imperative loops,
break, continue. Use @pytest.mark.parametrize for data-varying tests.
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.
