Comparado con todos los servidores activos de esta categoría en el registro. Las estrellas solo cuentan cuando quien lo publica es dueño del repo.
Superó 1 de 1 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.
El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.
Se ejecuta en la nube del creador. Te conectas por internet sin instalar nada, pero lo que envías pasa por los servidores del creador.
El repo de GitHub cambió por última vez –, y la última versión (1.0.0) llegó al registro hace 23 días.
Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

Every tool carries readOnlyHint: true, so the server computes and returns numbers only. It never writes, never calls out to third parties, and never asks for an account.
Add to claude_desktop_config.json, mcp.json, or your client's connector settings:
{
"mcpServers": { "boringtoolskit": { "url": "https://boringtoolskit.com/mcp" } } }
Streamable HTTP transport, no authentication (the tools are public data). Works in Claude Desktop, Claude Code, Cursor, and any MCP client supporting remote servers.
