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.

Security

Grade A, and why

using-react-hook-form-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 3d 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

Using react-hook-form-docs-mcp

When this MCP server is connected, prefer it over recalling React Hook Form APIs from memory — training data goes stale, this tool indexes the live official docs.

Workflow

  1. Search first. Call search_react_hook_form_docs with a natural-language query before writing form code that touches an API you're not 100% certain about (register options, validation rules, useFieldArray methods, resolver behavior). Results include a relevance-ranked snippet and a url.
  2. Drill in only when needed. If the search snippet isn't enough, call get_doc with the path from a search result. It returns a ~1500 char summary plus a structure outline by default.
  3. Use full: true sparingly. Pass full: true to get_doc only for long guides — Advanced Usage, the v7→v8 migration guide — where truncation would hide later steps. Don't default to full for short API reference pages.
  4. Search unfiltered by default. Only docs/ (the API reference) is a real section; guide pages (get-started, advanced-usage, faqs, ts) live at the content root and are missed by any section filter.
  5. Refresh if docs seem stale. Call update_docs to 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.
