_ is it live, free and safe measured by this hub
Is graphchinese live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is graphchinese free to use?
Yes — the hub reached it with no key and no payment.
What tools does graphchinese have?
6 tools: lookup_word, search_grammar, search_dictionary, segment_text, get_grammar_point, get_related_characters.
Is graphchinese safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 6 tools
6 never probed 0 of 6 classified

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.

  • lookup_word unknown never probed

    Look up one Chinese word or character, written in simplified or traditional characters. Returns its pinyin, every meaning, its HSK level, other readings of the same characters, each character it is made of, and the GraphChinese lessons that teach it. Use this when the user asks what a specific Chinese word means or how it is pronounced.

    }

  • search_grammar unknown 1h ago

    Search 195 Mandarin grammar points by keyword, by HSK level, or both. A keyword can be English (comparison, passive), a Chinese marker (把, 了) or a term name. Returns matching points with a one-paragraph summary and the slug that get_grammar_point takes. Use this to find which grammar point covers a pattern.

        }
      },
      "additionalProperties": false
    }
    arguments 19 lines
  • search_dictionary unknown never probed

    Search a Mandarin Chinese dictionary by Chinese characters, pinyin or an English word. Returns up to 10 matching words, each with its pinyin, a short meaning, its HSK level when it has one, and a link to its dictionary page. Use this when the user wants the Chinese for an English word, or does not know the exact headword.

    mcp-tool

    {
      "type": "object",
      "required": [

          "maxLength": 64,
          "minLength": 1,
          "description": "Chinese characters, pinyin (with or without tones) or English."
        }
      },
      "additionalProperties": false
    }
    arguments 15 lines
  • segment_text unknown never probed

    Split a Chinese sentence or short passage into words. Returns each word in order with its dictionary pinyin, a short meaning and its HSK level, plus a count of words per HSK level. The pinyin is each word's dictionary reading, not a reading chosen for this sentence. Use this to gloss a sentence word by word or to judge how hard a text is.

    mcp-tool

    {
      "type": "object",
      "required": [
        "text"

      "properties": {
        "text": {
          "type": "string",
          "maxLength": 1000,
          "minLength": 1,
          "description": "Chinese text, up to 1000 characters."
        }
      },
      "additionalProperties": false
    }
    arguments 15 lines
  • get_grammar_point unknown 1h ago

    Get one Mandarin grammar point by its slug. Returns the written explanation, worked example sentences with pinyin and English, a word-by-word note for each word in the pattern (what it does, structure, three examples, a common mistake), the grammar points that should be learned first, and the points this one leads to. Use this after search_grammar, when the user wants a pattern explained or wants to know what to study before it.

    mcp-tool

    {
      "type": "object",
      "required": [
        "slug"
      ],
      "properties": {
        "slug": {
          "type": "string",
          "pattern": "^[a-z0-9][a-z0-9-]*$",
          "maxLength": 80,
          "description": "A slug returned by search_grammar."
        }
      },
      "additionalProperties": false
    }
    arguments 15 lines
  • get_related_characters unknown 1h ago

    Show how one Chinese character connects to others. Returns the components it is built from, characters that contain it, characters that look similar and are easy to confuse with it, the other characters that share its sound component, and common words that start with or contain it. Use this when the user wants to learn a character through its parts, tell look-alike characters apart, or see a character family.

    mcp-tool

    {
      "type": "object",
      "required": [
        "character"
      ],
      "properties": {
        "character": {
          "type": "string",
          "maxLength": 4,
          "minLength": 1,
          "description": "Exactly one Chinese character, for example 请."
        }
      },
      "additionalProperties": false
    }

_ 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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 915b1ecd9d150029.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/915b1ecd9d150029/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/915b1ecd9d150029/badge.svg)](https://brick.blue/agent/915b1ecd9d150029?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ 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.
