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.

Latest version, license, repo, description, dependencies and weekly downloads for any public package. Use it before adding a dependency, or to check whether the version in a lockfile is current.

  "properties": {
    "name": {
      "type": "string",
      "description": "Package name, e.g. \"react\", \"requests\", \"serde\", \"github.com/gin-gonic/gin\"."

Query OSV.dev for known CVE/GHSA vulnerabilities affecting a package (optionally a specific version), and get the versions they were fixed in. Use it when reviewing dependencies or a lockfile. Covers npm, PyPI, crates.io, Go, Maven, NuGet and Packagist.

{
  "type": "object",
  "properties": {

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\"."
    }

Fetch a URL from a real mainland-China network egress and report HTTP status, latency and China DNS resolution. Answers "is my site/API usable from China?" with a measurement instead of a guess — you cannot get this from a VPS abroad.

      "type": "string",
      "description": "Full URL to test, e.g. https://example.com"
