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/nguyendat-lhd/notebypine-mcp/cursorrulesgit clone --depth 1 https://github.com/nguyendat-lhd/notebypine-mcpWhat 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 | $0.01419 | $0.01419 |
| Opus 5 | $0.00709 | $0.00709 |
| Sonnet 5 | $0.00284 | $0.00284 |
| Haiku 4.5 | $0.00142 | $0.00142 |
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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Notebypine MCP - Code Mode Rules
Primary Workflow: Code Mode Orchestration
When working with this codebase and MCP server, ALWAYS follow this pattern:
1. Tool Discovery First
- Use
agent/helpers/searchTools.tsto discover appropriate tools before calling them - Search with keywords like "incident", "solution", "export", "search" to find relevant tools
- Always check tool relevance scores and pick the highest-rated ones
2. Route Through Helper Stack
- NEVER call MCP tools directly - ALWAYS use
agent/helpers/callMCPTool.ts - Use
agent/helpers/router.tsfor automatic routing decisions - All calls should go through the wrapper functions, not direct MCP invocation
3. Security & Logging
- All logging is automatically redacted via
agent/helpers/redact.ts - Never log raw payloads or sensitive data
- Use sample-size logging (default 5-10 rows) for large datasets
- Enable verbose mode only when explicitly requested
4. Use Skills for Complex Workflows
- For log analysis: Use
agent/skills/triageFromLogfile.ts - For CSV exports: Use
agent/skills/saveSheetAsCSV.ts - For end-to-end workflows: Use
agent/examples/incident_to_kb.ts

Import Patterns
// ✅ GOOD: Route through helpers
import { callMCPTool } from '../helpers/callMCPTool.js';
import { searchTools } from '../helpers/searchTools.js';
import { routeCall } from '../helpers/router.js';
// ❌ AVOID: Direct MCP calls
// import { mcp } from '@modelcontextprotocol/sdk';
Typical Workflow
- Discovery:
searchTools("incident|solution|export") - Import: Import only required wrappers
- Execute: Use
callMCPTool()orrouteCall() - Log: Summaries are automatically logged (top 3 rows/items)
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 nguyendat-lhd/notebypine-mcp (0 stars, last pushed 9mo ago), licensed MIT. It adds 1,419 tokens to every session, about $0.0071 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 2026-09-01.
