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 5.1 | $0.00032 | $0.01348 |
| Opus 5 | $0.00016 | $0.00674 |
| Sonnet 5 | $0.00006 | $0.00270 |
| Haiku 4.5 | $0.00003 | $0.00135 |
Grade A, and why
cursor-mcp-optimization 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cursor 3.7 MCP Optimization
Current through Cursor 3.7 (Jun 2026). Direct guidance for Cursor's MCP and integrated surfaces. Use the right tool for each job.
Browser Tools (cursor-ide-browser)
Always do before any interaction:
1. browser_tabs with action: "list" -> check current tabs/URLs
2. browser_snapshot -> get current page structure and refs
Interaction pattern:
1. Identify the target ref from snapshot (use exact ref, not coordinates)
2. For clicks: prefer snapshot refs over mouse_xy coordinates
3. For forms: use browser_fill for existing content, browser_type to append
4. After ANY action that changes page: take fresh snapshot
Coordinate clicks ONLY when:
- A fresh screenshot confirms the exact visual target
- No snapshot ref is available
- The target is visually verifiable (button, link)
Never do:
- Click without a fresh snapshot first
- Reuse old screenshot coordinates
- Assume page state without verification
Browser Design Mode (Cursor 3.7)
Design Mode is a user-driven overlay in the integrated browser — agents do not invoke it as a tool. When the user selects elements there, treat those selections as ground truth for UI edits (same discipline as multimodal-grounded):
- Multi-select: two or more elements selected together carry code, layout, and visual relationships — use them for parity edits, deduplication, or batch component tweaks.
- Voice input: transcribed voice instructions are user intent; honor them even if the agent is mid-run.
- Agent path unchanged: still snapshot → ref-based interaction for automation; Design Mode complements, not replaces, the MCP browser flow.
Canvas (Cursor 3.7)
Canvases are live React artifacts beside the chat — dashboards, reports, analyses, internal tools. Load the canvas skill before creating or editing .canvas.tsx files.
When to use a canvas:
- Structured MCP or tabular deliverables where the data is the output (prefer canvas over markdown tables)
- Interactive reports the user may share or iterate on (context usage breakdowns, audits, timelines)
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.

cursor-mcp-optimization is a cursor rule published in the GitHub repository madebyaris/advance-minimax-m3-cursor-rules (125 stars, last pushed 2mo ago), licensed MIT. It adds 32 tokens to every session and 1,348 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.
