Describe a task in plain language (any language) and get back exactly which tools on this server do it, with ready-to-run example calls — instead of reading the whole catalogue and guessing. Also returns multi-step recipes when a task needs several tools chained (invoices to a ledger, a bank statement reconciled, a messy CSV turned into a deliverable). Deterministic and free: it calls no model, costs nothing, and never runs out of quota. Call this FIRST when you are not sure what this server offers.

{
  "type": "object",
  "properties": {
    "task": {
      "type": "string",
      "description": "What you are trying to do, e.g. \"reconcile a bank statement against my books\" or \"把一堆发票整理成能入账的表格\""
    }
  },
  "required": [
    "task"
  ]
}

Strip emails, phone numbers, ID numbers, API keys, private keys, JWTs, card numbers and IPs out of text, returning the redacted text plus a mapping table to restore them afterwards. Rule-based only — no model sees the input. The same value always maps to the same placeholder, so the answer can be restored.

{
  "type": "object",
  "properties": {
    "text": {
      "type": "string",
      "description": "The text to redact."
    },
    "only": {
      "type": "string",
      "description": "Optional comma-separated subset, e.g. \"EMAIL,API_KEY,PRIVATE_KEY\"."
    }
  },
  "required": [
    "text"
  ]
}

  "type": "object",

}

Converts JSON to YAML or YAML to JSON. It works out which one you gave it, so you do not have to say. A parse failure comes back with the parser message instead of silently producing something that looks fine and is not. Use when a config, a CI file, or a Kubernetes manifest needs to be in the other format.

{
  "type": "object",
  "properties": {
    "text": {
      "type": "string",
      "description": "The JSON or YAML content."
    },
    "to": {
      "type": "string",
      "description": "Optional: \"json\" or \"yaml\" to force the direction."
    }
  },
  "required": [
    "text"
  ]
}

{
  "type": "object",
  "additionalProperties": true
}

Checks that text parses as JSON, and optionally that required keys are present with the right top-level types. Returns the specific violations, not just true/false. Checks required + types only — not full JSON Schema, and it says so rather than pretending. Use before feeding generated JSON into something that will fail on it.

{
  "type": "object",
  "properties": {
    "text": {
      "type": "string",
      "description": "The JSON to validate."
    },
    "schema": {
      "type": "string",
      "description": "Optional JSON Schema (as JSON text) — required[] and properties[].type are checked."
    }
  },
  "required": [
    "text"
  ]
}

{
  "type": "object",
  "additionalProperties": true
}

Returns which lines were added and which were removed, with line numbers — computed with a longest-common-subsequence, not guessed by a model. Use to compare two versions of a config, a document, or any command output, instead of asking an LLM to eyeball two blobs and hoping it notices.

{
  "type": "object",
  "properties": {
    "a": {
      "type": "string",
      "description": "The first (before) text."
    },
    "b": {
      "type": "string",
      "description": "The second (after) text."
    }
  },
  "required": [
    "a",
    "b"
  ]
}

{
  "type": "object",
  "additionalProperties": true
}

Decodes the header and payload of a JWT and reports issued-at / expiry as readable timestamps plus seconds remaining. The signature is NOT verified and the response says so — decoding is fine for debugging a token you already hold, but never treat these values as proof of anything; verification needs the secret and belongs in your own service.

{
  "type": "object",
  "properties": {
    "token": {
      "type": "string",
      "description": "The JWT string."
    }
  },
  "required": [
    "token"
  ]
}

{
  "type": "object",
  "additionalProperties": true
}

Runs a regular expression against sample text and returns every match with its position and capture groups (named groups included). Use before wiring a pattern into code, instead of guessing whether the escaping survived the trip through JSON and the shell.

{
  "type": "object",
  "properties": {
    "pattern": {
      "type": "string",
      "description": "The regular expression, without surrounding slashes."
    },
    "text": {
      "type": "string",
      "description": "The text to test against."
    },
    "flags": {
      "type": "string",
      "description": "Optional flags, e.g. \"gi\". Default \"g\"."
    }
  },
  "required": [
    "pattern",
    "text"
  ]
}

{
  "type": "object",
  "additionalProperties": true
}

Convert a SQL statement from one dialect to another — mysql, postgres, sqlite, tsql, oracle, snowflake, bigquery, redshift, spark, hive, presto, trino, duckdb, clickhouse, databricks, doris, starrocks and more. Deterministic parser (sqlglot), not an LLM: the same input always produces the same output, and syntax errors come back with the exact line and column. Use it when migrating queries between databases or debugging dialect-specific syntax.

{
  "type": "object",
  "properties": {
    "sql": {
      "type": "string",
      "description": "The SQL statement (or several, separated by semicolons)."
    },
    "read": {
      "type": "string",
      "description": "Source dialect, e.g. \"mysql\". Omit to auto-detect from generic SQL."
    },
    "write": {
      "type": "string",
      "description": "Target dialect, e.g. \"postgres\", \"bigquery\", \"doris\"."
    }
  },
  "required": [
    "sql",
    "write"
  ]
}

  "type": "object",
  "additionalProperties": true

Any text or URL → a QR code PNG you can embed or download. Stateless URL form: https://ainetcafe.com/i/qr/<text>

{
  "type": "object",
  "properties": {
    "text": {
      "type": "string",
      "description": "The text or URL to encode."
    }
  },
  "required": [
    "text"
  ]
}

{
  "type": "object",
  "additionalProperties": true
}

Validate and pretty-print JSON (2-space indent). Reports the error location if invalid.

{
  "type": "object",
  "properties": {
    "json": {},
    "url": {},
    "indent": {
      "type": "number"
    }
  },
  "additionalProperties": true
}

Convert a time between time zones, or get current time in any zone. from/to = IANA zone (Asia/Shanghai), time = YYYY-MM-DDTHH:mm (default now).

{
  "type": "object",
  "properties": {
    "to": {
      "type": "string"
    },
    "from": {
      "type": "string"
    },
    "time": {
      "type": "string"
    }
  },
  "additionalProperties": true
}

Convert units: length, weight, temperature, area, volume, speed, data size. value + from + to (e.g. 100 km mi, 25 c f).

{
  "type": "object",
  "properties": {
    "value": {
      "type": "number"
    },
    "from": {
      "type": "string"
    },
    "to": {
      "type": "string"
    }
  },
  "additionalProperties": true
}

Plain-language request + table schema → ready-to-run .sql file with comments.

{
  "type": "object",
  "properties": {
    "request": {},
    "schema": {
      "type": "string"
    },
    "dialect": {}
  },
  "additionalProperties": true
}

Full-page screenshot of any URL → PNG. The same job screenshot APIs charge $7-79/month for.

{
  "type": "object",
  "properties": {
    "url": {},
    "width": {
      "type": "number"
    }
  },
  "additionalProperties": true
}
