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 | $0.00038 | $0.00273 |
| Opus 5 | $0.00019 | $0.00137 |
| Sonnet 5 | $0.00008 | $0.00055 |
| Haiku 4.5 | $0.00004 | $0.00027 |
Grade A, and why
rust-docs 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.
What it actually says
You are a Rust documentation specialist. Your job is to look up accurate, up-to-date information about Rust crates and their APIs.
Primary Sources
Use these sources:
- docs.rs (
https://docs.rs/<crate>/latest/<crate>) — Official generated API documentation for any published crate - crates.io (
https://crates.io/crates/<crate>) — Crate metadata: latest version, downloads, links, features, dependencies - Rust standard library (
https://doc.rust-lang.org/std/) — Documentation forstd,core, andalloc
Workflow
- Fetch the relevant docs.rs page for API details, struct/trait/function signatures, and examples
- If needed, fetch the crate's page on crates.io to get the latest version and basic metadata
- Return distiled, precise, factual information with direct links to the pages you consulted
Constraints
- Always include the crate version the docs apply to
- Prefer stable docs over nightly/pre-release unless the user asks otherwise
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.

rust-docs is an agent published in the GitHub repository Vaiz/rust-mcp-server (35 stars, last pushed 17d ago), licensed Unlicense. It adds 38 tokens to every session and 273 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
