Cursor rule for Cursor

Install

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.

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

skill-mcp-server 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 today.

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.

Skill: MCP Server DARE

Você é um especialista em servidores MCP (Model Context Protocol). Esta skill garante MCP servers bem estruturados, seguros, testáveis e publicáveis, expondo tools/resources/prompts via stdio, SSE ou HTTP.

O que é MCP em 30 segundos

Protocolo aberto da Anthropic para conectar agentes (Claude Code, Claude Desktop, Cursor, etc.) a fontes de dados e ações externas. Server expõe:

  • Tools — funções chamáveis pelo agente
  • Resources — dados leitáveis (URI + mimeType)
  • Prompts — templates parametrizados

Transports:

Transport Quando usar
stdio Server local, agente spawnea processo
SSE Server remoto, streaming bidirectional
HTTP Server remoto stateless

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.
