Construye con SmeltSec

Todo lo que necesitas para generar, proteger, mantener y monitorear servidores MCP.

Quick start

Five questions most people ask first

The fastest path from zero to a running SmeltSec pipeline.

Install the CLI globally with `npm install -g @smeltsec/cli`, or run one-off commands via `npx @smeltsec/cli`. The package is MIT-licensed and works on macOS, Linux, and Windows (WSL). No Docker image required.

Server code generation targets Python 3.11 (FastMCP) and TypeScript (MCP TypeScript SDK). Source-code analysis via Tree-sitter covers Python, TypeScript, JavaScript, Go, Rust, Java, and Ruby. Additional targets are rolling out on Team and Enterprise plans.

Yes. The Free plan includes unlimited local generation, all 15 free scanners in Gate 1, quality scoring, and config sync for one machine. Gate 2 behavioral analysis is the only paid step (≈ $0.02 per scan) and is only run on Team plans and above.

For a medium REST API (12–20 endpoints) the full eight-step pipeline finishes in under 60 seconds. Large repos with hundreds of files can take a few minutes, most of it spent in Tree-sitter parsing.

The CLI and core libraries live at github.com/smeltsec. The npm packages (@smeltsec/cli, @smeltsec/core, @smeltsec/proxy, @smeltsec/sync) are all open source under MIT. Only the behavioral analysis backend is closed.

Inicio Rápido

quick-start

Instalar el CLI

npm install -g @smeltsec/cli
smeltsec --version

Genera tu primer servidor

# From a GitHub repo
smeltsec generate --from github:owner/repo

# From an OpenAPI spec
smeltsec generate --from ./openapi.yaml

# From a natural language description
smeltsec generate --prompt "Create a Stripe MCP server"

Qué sucede durante la generación

Análisis del código fuente mediante análisis AST de Tree-sitter

Escaneo de seguridad Gate 1 (SAST, secretos, CVEs)

Generación de código del servidor MCP (FastMCP o TypeScript SDK)

Escaneo de seguridad Gate 2 (envenenamiento de herramientas, análisis de comportamiento)

Puntuación de calidad + seguridad con informes

Generación de configuración de clientes (Claude Desktop, Cursor, VS Code, etc.)

Instalar la configuración

# Auto-install config for Claude Desktop
smeltsec config install --client claude_desktop

# Or copy manually
cp ./mcp-server/claude_desktop_config.json ~/.config/claude/
