presto-usage

presto-usage is a skill for Claude Code, Codex from NeoNexAI/presto-mcp-server. It costs 183 tokens per session (1,561 once invoked), scanned A, original, MIT.

A guide for using the Presto MCP tools with construction budgets. Presto is construction estimating software; BC3/FIEBDC-3 is a file format for exchanging construction budgets and measurements.

In plain words
What is it for?
Use it when reading, editing, checking, exporting, or measuring Presto budgets, certifications, prices, or BC3 files.
Why use it?
It helps choose between controlling an open Presto installation and reading a BC3 file, avoiding failed connections and incorrect operations.

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

presto-usage 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 9d 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.

Presto — cómo usar el MCP bien

Hay dos vías y elegir la correcta evita el 90% de los problemas:

  • COM (en vivo): controla la obra abierta en Presto. Es la mayoría de tools. Requiere Presto 2025 instalado Y ABIERTO en este mismo equipo, con la obra abierta para operar sobre ella.
  • BC3 (ficheros): las tools presto_bc3_* leen/analizan ficheros .bc3 (FIEBDC-3) sin Presto. Úsalas para auditar/consultar un presupuesto que te pasan como fichero, aunque Presto no esté instalado.

Flujo correcto (COM)

  1. Empieza SIEMPRE con presto_status. Confirma que Presto responde por COM y el ProgID activo. Si falla: Presto no está abierto, o la versión no casa con el ProgID (Presto 2025 = Presto.App.25; otra versión → variable PRESTO_PROGID).
  2. Asegúrate de que la obra correcta está abierta (presto_open_obra si hace falta abrir un .Presto concreto).
  3. Lee/opera con las tools.

Si algo falla o vas a reportar un bug: presto_selftest primero

Antes de ir probando tools sueltas (o de pedirle al cliente que pruebe una a una por chat), ejecuta presto_selftest. Es de solo lectura, no toca la obra, y en una sola llamada comprueba: conexión, abrir la tabla Conceptos, leer los primeros registros, buscar por código y buscar por resumen — exactamente las rutas donde han aparecido los bugs reales hasta ahora. Devuelve un informe con OK/FALLO paso a paso; pégalo entero al reportar un problema, ahorra varias idas y vueltas.

Modelo de datos: Tabla.Campo

Presto organiza todo en tablas con campos. Los nombres exactos se ven en Presto con Ver: Lista de campos; si una instalación difiere, ajusta el nombre. Los clave:

  • Tabla Conceptos: Conceptos.Código (clave única), Conceptos.Resumen, Conceptos.Ud, y precios por escenario: Conceptos.PrPres (presupuesto), PrCert (certificación), PrReal, PrObj (objetivo), PrPlan (planificado).
  • El filtro usa comodines de Presto: "E04*", "*hormigón*", "*".

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.
