skill-mcp-server

skill-mcp-server is a command for Claude Code from dewtech-technologies/dare-method. It costs 0 tokens per session (1,610 once invoked), scanned A, original, MIT.

A set of coding patterns for building MCP servers in TypeScript or Python. MCP, the Model Context Protocol, lets an AI agent call tools and read data exposed by a server.

In plain words
What is it for?
Use it to audit or scaffold MCP servers with tools, resources, prompts, and local or remote connections.
Why use it?
It helps structure the server, validate inputs, control tool access, trace requests, test the code, and publish it.

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 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.

/skill-mcp-server

Padrões DARE para servidores MCP (Model Context Protocol) em TypeScript ou Python. Tools, resources, prompts; transports stdio/SSE/HTTP; validação Zod/Pydantic; autorização por tool; tracing; testes; publicação.

Como usar

/skill-mcp-server                            # audita server MCP atual
/skill-mcp-server scaffold ts                # scaffold TypeScript stdio
/skill-mcp-server scaffold py                # scaffold Python stdio

O que é MCP

Protocolo aberto da Anthropic para conectar agentes a fontes de dados e ações. Server expõe:

  • Tools — funções chamáveis (ex: create_issue)
  • Resources — dados leitáveis (ex: schemas)
  • Prompts — templates parametrizados

Transports: stdio (local), SSE (remoto streaming), HTTP (remoto stateless).

Stack (TypeScript)

  • Node 20+ + TS 5.5+
  • @modelcontextprotocol/sdk
  • Zod para schemas
  • vitest

Stack (Python)

  • Python 3.11+
  • mcp (SDK oficial)
  • Pydantic v2
  • pytest + pytest-asyncio

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 command published in the GitHub repository dewtech-technologies/dare-method (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,610 tokens. 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.
