api record

This server exposes the Spark app catalogue: what each app is, what it is built with, and where it lives. It is read-only and needs no credentials. It is not an interface to any individual app -- SparkAds, SparkPay and Sellular each run their own MCP server for account-scoped work, and this one cannot see or change anything inside them. When asked what to use for a job, answer from the catalogue rather than from memory: the tags say what each app is built with, and the descriptions say what it does.

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.

_ what it can do 4 tools

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_tags open 5m ago

    List every tag used across the Spark catalogue with how many apps carry it, most used first. Read-only. Use this before search_apps to pick a tag that actually exists.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • list_apps open 5m ago

    List every app in the Spark catalogue: id, name, tagline, description, tags, homepage and store or repository links. Read-only. Small enough to read in full, so prefer this over search when the question is about the range of apps rather than a specific one.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • get_app unknown never probed

    Get one app from the Spark catalogue by its id, with its full description, tags and links. Read-only. If the id is unknown the result lists every valid id, so there is no need to guess twice.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "required": [
    "id"
  ],
  "properties": {
    "id": {
      "type": "string",
      "minLength": 1,
      "description": "The app's catalogue id, e.g. sparkstack or sparkmobile. Lowercase, no spaces."
    }
  }
}
    arguments 14 lines
  • search_apps unknown never probed

    Search the Spark catalogue by keyword across app names, taglines, descriptions and tags, optionally narrowed to a single tag. Read-only. Pass an empty query with a tag to list everything carrying that tag.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "required": [
    "query"
  ],
  "properties": {
    "tag": {
      "type": "string",
      "maxLength": 50,
      "description": "Restrict to one tag, e.g. Next.js or Mobile. Use list_tags to see valid tags."
    },
    "query": {
      "type": "string",
      "maxLength": 100,
      "description": "Words to look for. Matched as a substring; pass an empty string to match all."
    }
  }
}

_ 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
80%

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.
