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.
npx agentmods add rules/fradser/mcp-server-local-web-search/cursorrulesgit clone --depth 1 https://github.com/FradSer/mcp-server-local-web-searchWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00151 | $0.00151 |
| Opus 5 | $0.00076 | $0.00076 |
| Sonnet 5 | $0.00030 | $0.00030 |
| Haiku 4.5 | $0.00015 | $0.00015 |
Grade A, and why
cursorrules 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
This project use bun for runtime.
- Follow the user's requirements exactly as provided.
- Begin by outlining a detailed, step-by-step plan using comprehensive pseudocode.
- Once the plan is confirmed, proceed to write the code.
- Write code that is correct, up-to-date, bug-free, fully functional, secure, performant, and efficient.
- Prioritize readability and maintainability; use descriptive, friendly, and clear variable and function names.
- Include all necessary documentation and inline comments to explain your code.
- Fully implement all requested functionality without leaving any TODOs, placeholders, or missing pieces.
- Be concise and minimize any extraneous prose.
- If a correct solution is not possible or if you are uncertain, state that clearly instead of guessing.
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.

cursorrules is a cursor rule published in the GitHub repository FradSer/mcp-server-local-web-search (11 stars, last pushed 1y ago), licensed MIT. It adds 151 tokens to every session, about $0.0008 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 2026-08-31.
