skill-mcp-server

skill-mcp-server is a cursor rule for Cursor from dewtech-technologies/dare-method. It costs 0 tokens per session (2,450 once invoked), scanned A, original, MIT.

A set of rules for building MCP servers. MCP, or Model Context Protocol, is a standard way for AI agents to use tools, read data, and apply reusable prompts from another program.

In plain words
What is it for?
It is for creating MCP servers in TypeScript or Python that expose tools, resources, and prompts over local or remote connections.
Why use it?
It helps keep agent-connected services structured, validated, authorized, observable, tested, and ready to publish.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/. Also seen: mentions Claude Code.

Good fit It is for creating MCP servers in TypeScript or Python that expose tools, resources, and prompts over local or remote connections.

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 1mo 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.

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.
