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 | $0.02450 | $0.02450 |
| Opus 5 | $0.01225 | $0.01225 |
| Sonnet 5 | $0.00490 | $0.00490 |
| Haiku 4.5 | $0.00245 | $0.00245 |
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.
How it starts
The opening of the file, as written. The whole thing — 368 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 |

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.

skill-mcp-server is a cursor rule published in the GitHub repository dewtech-technologies/dare-method (5 stars, last pushed 1mo ago), licensed MIT. It adds 2,450 tokens to every session, about $0.0123 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 2026-09-03.
