The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_source_files unknown never probed

    Lists the raw source files (`.java`, `.kt`, and `.scala`) in a Maven Central artifact version's `-sources.jar`. Each returned path can be passed to get_source_file to read the actual source code. Use this only when you need the implementation — for example, to trace behavior or see how something is wired. To discover which classes exist, or to find classes by topic or name, use list_javadoc_symbols instead; do not use this tool just to enumerate classes. Works against the live Maven Central catalog with no local install, build, or checkout required.

  • get_javadoc_index unknown never probed

    Fetches the rendered Javadoc/Scaladoc index page for a specific Maven Central artifact version, converted to plain text/markdown. Useful for orienting yourself in an unfamiliar library: it lists the top-level packages, modules, and (for Scaladoc) often a curated overview. Use this before drilling into specific symbols. Works against the live Maven Central catalog — you do not need to download the javadoc jar.

}
    arguments 23 lines
  • list_javadoc_symbols unknown never probed

    Enumerates the public API a library documents — classes, interfaces, traits, objects, enums, and annotations — for a Maven Central artifact version. Each entry includes the fully-qualified class name (`fqn`) and a `link` that can be passed to get_javadoc_symbol to read the rendered API documentation. Use this to answer 'which classes/types does library X have?' or 'find classes related to <topic>' — it is the fastest way to list the API by name without reading code. Prefer this over list_source_files whenever you only need class/type names. Only if this returns NotFoundError because no javadoc jar was published, fall back to list_source_files. Works against the live Maven Central catalog with no local install, build, or checkout required.

}
    arguments 23 lines
  • get_latest_version unknown never probed

    Resolves the latest published version of a Maven Central artifact (any groupId:artifactId — Java, Kotlin, or Scala library). Call this first when you only know the artifact but not the version: the version it returns feeds into every other tool here that takes a concrete version. Works against the live Maven Central catalog — no local install, build tool, or repository checkout required.

    mcp-tool

    {
  "type": "object",
  "required": [
    "groupId",
    "artifactId"
  ],
  "properties": {
    "groupId": {
      "type": "string",
      "description": "The Maven groupId, e.g. \"dev.zio\"."
    },
    "artifactId": {
      "type": "string",
      "description": "The Maven artifactId, e.g. \"zio_3\"."
    }
  },
  "description": "A Maven Central artifact coordinate: a groupId and artifactId, without a version."
}
    arguments 18 lines
  • get_javadoc_symbol unknown never probed

    Reads one Javadoc/Scaladoc page from a Maven Central artifact, already converted to plain text/markdown so you don't have to parse HTML. Pass the `link` value returned by list_javadoc_symbols. Use this when you need to know what a class, method, or field does and what its parameters mean for any library on Maven Central — without downloading or unzipping the javadoc jar yourself.

    mcp-tool

    {
  "type": "object",
  "required": [
    "groupId",
    "artifactId",
    "version",
    "link"
  ],
  "properties": {
    "link": {
      "type": "string",
      "description": "The relative path/link within the jar, as returned by list_javadoc_symbols or list_source_files."
    },
    "groupId": {
      "type": "string",
      "description": "The Maven groupId, e.g. \"dev.zio\"."
    },
    "version": {
      "type": "string",
      "description": "The artifact version, e.g. \"2.1.9\"."
    },
    "artifactId": {
      "type": "string",
      "description": "The Maven artifactId, e.g. \"zio_3\"."
    }
  },
  "description": "A pointer to one documented page or source file inside an artifact's jar."
}
    arguments 28 lines
  • get_source_file unknown never probed

    Reads one source file from a Maven Central library's sources jar (the `-sources.jar` artifact). Pass the `link` value returned by list_source_files. Use this whenever you need the exact source text of a JVM library — tracing behavior into a dependency, confirming a public API's implementation, finding a definition, or comparing two library versions. Strongly preferred over locating the jar in a local build cache and unzipping it: it works for any Maven Central artifact, no local checkout or build needed.

    mcp-tool

    {
  "type": "object",
  "required": [
    "groupId",
    "artifactId",
    "version",
    "link"
  ],
  "properties": {
    "link": {
      "type": "string",
      "description": "The relative path/link within the jar, as returned by list_javadoc_symbols or list_source_files."
    },
    "groupId": {
      "type": "string",
      "description": "The Maven groupId, e.g. \"dev.zio\"."
    },
    "version": {
      "type": "string",
      "description": "The artifact version, e.g. \"2.1.9\"."
    },

    }
  },
  "description": "A pointer to one documented page or source file inside an artifact's jar."
}
    arguments 28 lines
  • search_artifacts unknown never probed

    Searches the indexed Maven Central catalog for artifacts whose groupId or artifactId contains a substring (case-insensitive). Use this when you know part of a library name (e.g. "jackson", "zio-http", "netty-codec") and need the exact groupId:artifactId coordinates to feed into the other tools. Pair with get_latest_version once you've picked an artifact.

    mcp-tool

    {
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "query": {
      "type": "string",
      "description": "The text to search for — e.g. a class/type name, a package, or part of a groupId/artifactId."
    }
  },
  "description": "A search query."
}
    arguments 13 lines
  • symbol_to_artifact unknown never probed

    Resolves a class name, fully-qualified type, or package name to the Maven Central artifact (groupId, artifactId) that publishes it. Case-sensitive. Use this when you have a symbol from a stack trace, an import line, or an error message and you need to know which library to look in. From there, chain into get_latest_version, then list_source_files / list_javadoc_symbols to read the code or docs.

    mcp-tool

    {
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "query": {
      "type": "string",
      "description": "The text to search for — e.g. a class/type name, a package, or part of a groupId/artifactId."
    }
  },
  "description": "A search query."
}

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
