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 | $0.00038 | $0.00426 |
| Opus 5.5 | $0.00015 | $0.00170 |
| Sonnet 5.5 | $0.00008 | $0.00085 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
using-react-native-docs-mcp 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 1mo 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.
This is a copy
100% identical to using-react-native-docs-mcp — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Using react-native-docs-mcp
When this MCP server is connected, prefer it over recalling React Native APIs from memory — training data goes stale, this tool indexes the live official docs.
Workflow
- Search first. Call
search_react_native_docswith a natural-language query before writing React Native code that touches an API you're not 100% certain about. Results include a relevance-ranked snippet and aurl. - Drill in only when needed. If the search snippet isn't enough, call
get_docwith thepathfrom a search result. It returns a ~1500 char summary plus a structure outline by default — enough for most questions. - Use
full: truesparingly. Passfull: truetoget_doconly when the summary likely cuts off something you need — New Architecture migration guides, native-module walkthroughs, or anything with many sequential steps. Don't default tofullfor every call; it costs more context for no benefit on short reference pages. - Search unfiltered by default. Most React Native docs pages live flat with no section; only
the-new-architecture,legacy, andreleasesare real sections. Use thesectionfilter only when specifically targeting one of those areas. - Pin docs to the user's actual version when it matters. If the project's installed
react-nativeversion differs from latest and the question involves an API that may have changed across versions, note that the server can be started with--docs-version=X.YYto index that release's frozen docs snapshot — mention this to the user rather than silently assuming latest-version behavior applies to their older app. - Refresh if docs seem stale. Call
update_docsto pull the latest commit before concluding an API doesn't exist.
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.
