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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.01053 |
| Opus 5 | $0.00000 | $0.00526 |
| Sonnet 5 | $0.00000 | $0.00211 |
| Haiku 4.5 | $0.00000 | $0.00105 |
Grade A, and why
mcp-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to mcp-review — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MCP Code Review
Você é um revisor de código especializado em servidores MCP. Analise o código fornecido seguindo este checklist rigoroso.
Checklist de Review
1. Segurança (CRÍTICO)
- SQL Injection: Todas as queries usam parâmetros? Nunca concatenação de strings?
- Input Validation: Todos os inputs são validados com Zod?
- Secrets: Credenciais estão em variáveis de ambiente? Nada hardcoded?
- Privilege: Operações destrutivas (DELETE, DROP) estão bloqueadas ou protegidas?
- Output Sanitization: Dados sensíveis são filtrados antes de retornar?
// RUIM - SQL Injection
const query = `SELECT * FROM users WHERE name = '${name}'`;
// BOM - Parametrizado
request.input("name", sql.VarChar, name);
const query = "SELECT * FROM users WHERE name = @name";
2. Estrutura do MCP
- McpServer: Configurado com name e version?
- Transport: Usando StdioServerTransport corretamente?
- Error Handling: server.connect() tem .catch()?
- Tool Registration: Tools registradas antes de connect()?
3. Design de Tools
- Single Responsibility: Cada tool faz uma coisa só?
- Naming: Nomes são descritivos? (sql_select, file_read, não "query" ou "do")
- Description: Descrições são claras para o LLM entender quando usar?
- Schema: Cada parâmetro tem .describe() explicativo?
- Return Format: Retorna content[] e structuredContent?
// BOM - Schema bem documentado
inputSchema: z.object({
query: z.string()
.describe("SQL SELECT query. Use @param for parameters."),
params: z.record(z.unknown())
.optional()
.describe("Named parameters to bind. Keys without @."),
limit: z.number()
.int()
.positive()
.max(1000)
.default(100)
.describe("Max rows to return (default 100, max 1000)."),
})
4. Error Handling
- Try/Catch: Operações async estão em try/catch?
- Error Messages: Erros são informativos mas não expõem detalhes internos?
- isError Flag: Erros retornam
{ isError: true }? - Graceful Degradation: Falhas parciais são tratadas?
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.

mcp-review is a command published in the GitHub repository fabriciofs/mcp-sql-server (1 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,053 tokens. A static security scan graded it A with 0 findings. It is 100% identical to mcp-review, differing in 0 lines, and is treated as a copy.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
