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 C, and why

gasolineras-mcp CLAUDE.md scanned grade C with 2 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 10d 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.

gasolineras-mcp

Servidor MCP local (stdio) en Python que da precios de carburantes de cualquier municipio de España, sobre la API pública del MINETUR (sin clave). Público objetivo: usuarios de Claude Desktop/Code que no son programadores.

Estado

v1 construida, verificada y funcionando en Claude Code (smoke test del autor superado el 16/07/2026, servidor registrado con claude mcp add -s user). Dos tools MCP, cliente sin red en tests, gasolineras_mcp/res/municipios.json generado contra la API real. Pasó una ronda de revisión adversarial (16/07/2026) que encontró 3 blockers — matching de municipios con artículo gallego/catalán ("La Coruña"), wheel no editable roto por ruta de datos fuera del paquete, y excepciones crudas en inglés ante red/JSON inválido — y varias mejoras (validación de limite, mensaje más prudente en "sin_gasolineras", alias "gasoil", metadata de pyproject.toml). Todo corregido, retesteado (41 tests) y reconfirmado por el revisor.

PUBLICADO el 17/07/2026: repo público (github.com/gregoriofraile/gasolineras-mcp), PyPI (pypi.org/project/gasolineras-mcp/, v0.1.0), release v0.1.0. Verificado end-to-end: uvx gasolineras-mcp desde PyPI + consulta real en sesión nueva de Claude Code. El plan de publicación pasó revisión adversarial (17/07/2026). El upload a PyPI lo ejecuta el autor en su terminal — el token nunca pasa por sesiones de Claude (regla permanente para releases). Cuenta PyPI: greg-lezolab. Fixture de tests: Teruel (id 6716). Commits con email noreply de GitHub, autor "Gregorio Fraile".

Pendiente: (1) topics del repo (la API de GitHub daba 503 — reintentar gh repo edit --add-topic mcp --add-topic mcp-server --add-topic model-context-protocol --add-topic spain --add-topic gasolineras --add-topic open-data --add-topic claude o ponerlos en la web), (2) re-scope del token de PyPI a project-scoped (lo hace el autor en pypi.org), (3) Fase 2 — directorios MCP, en este orden: (a) topics puestos, (b) PR a punkpeye/awesome-mcp-servers (fork + una línea en la categoría correspondiente, one-liner en inglés — usar el blurb English del pie del README), (c) comprobar/reclamar ficha en Glama (glama.ai/mcp/servers) y PulseMCP, que auto-indexan desde GitHub, (4) el repo solo habla al ecosistema Claude en dos sitios detectados el 17/07 — pulir para 0.1.1: (a) README: decir explícitamente en la vía rápida que NO hace falta tener Python instalado (uv lo gestiona; el "Python 3.10" de la vía pedagógica asusta al lector de letras sin aplicarle) y valorar renombrar esa vía a "para curiosos"; la redacción es del autor; (b) multiagente: AGENTS.md como fichero canónico de instrucciones (estándar leído por Codex, opencode, Gemini CLI...) con CLAUDE.md como symlink. Versiones publicadas en PyPI son inmutables: los errores se corrigen con 0.1.1, nunca borrando. uvx cachea: usuarios no reciben updates hasta uv cache clean o @latest.

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.
