Calidad y seguridad
Basado en el análisis automatizado de las definiciones de herramientas y el cumplimiento del protocolo.
Costo de contexto
Este es el número aproximado de tokens que se consumen cada vez que las herramientas del servidor se cargan en el contexto de un modelo. Los recuentos más altos reducen la atención disponible para otras tareas.

Herramientas (6)
🟢get_time(server, timezone)
Query an NTP server for current UTC time and this clock's offset. Appends the sample to the drift log and returns the trend inline: current offset, drift rate (ms/day), and whether the clock is stable, drifting, or accelerating.

"timezone": {
"type": "string",
"description": "IANA timezone for a 'local' field, e.g. America/New_York. Optional -- the HTTP transport also takes ?tz= in the URL."
}
}
}⚪generate_uuid(count)
Generate one or more random UUIDv4 identifiers -- for records, sessions, and IDs created in agent pipelines.

"description": "How many UUIDs to generate",
"default": 1,
"minimum": 1,
"maximum": 1000
}
}
}⚪diff(text_a, text_b, context)
Unified diff between two texts, with added/removed line counts. For reviewing edits, comparing outputs, or validating transformations.

"type": "object",
"properties": {
"text_a": {
"type": "string",

},
"context": {
"type": "integer",
"description": "Lines of context around each change",
"default": 3,
"minimum": 0
}
},
"required": [
"text_a",
"text_b"
]
}🟢calculate(expression)
Evaluate a math expression safely: + - * / // % **, parentheses, functions (abs round min max sqrt floor ceil exp log log2 log10 pow sin cos tan), constants pi e tau inf. Parsed to an AST and only whitelisted nodes are computed -- no eval(), no names, no arbitrary code.

"expression": {
"type": "string",
"description": "e.g. \"(1500 * 0.23) + 47\""
}
},
"required": [
"expression"
]
}⚪attest(payload, server)
Wrap any payload in a tamper-evident record: a UUID, a timestamp (NTP-verified when reachable, local clock otherwise -- the record says which), and a sha256 over the canonical record. One call, the record is complete and tamper-evident.

{
"type": "object",
"properties": {
"payload": {
"description": "Any JSON value to attest"
},
"server": {
"type": "string",
"description": "NTP server for the verified timestamp",
"default": "time.cloudflare.com"
}
},
"required": [
"payload"
]
}🟢verify(attested)
Check a record produced by attest: recompute the sha256 over the record and compare. Pass/fail -- did this payload produce this hash at this timestamp. Any modified field breaks it.
