_ used through this hub 30 days

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_dossiers reads unknown never probed

    List every published AB[500] artist dossier (name, slug, subtitle, editions, tier, updated date). Start here to discover which artists have a biography available.

    mcp-tool

  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • search_artists reads unknown never probed

    Search AB[500] artist dossiers by name or keyword; returns matching artists with their slugs. Use before get_dossier when you don't know the exact slug.

  "type": "object",
  "required": [
    "query"
  ],
  "properties": {

  "additionalProperties": false
}
    arguments 13 lines
  • get_dossier reads unknown never probed

    Get one artist's full structured biography by slug: subtitle, essay prose (markdown), identity (born/based/practice), works, images, and the verified bibliography with source URLs. Prose is CC0.

  "required": [
    "slug"
  ],
  "properties": {
    "slug": {

  • get_otdh_methodology reads unknown never probed

}
    arguments 5 lines
  • list_artist_otdh reads unknown never probed

    List the ranked oTDH records for all 308 AB[500] artists, or a limited leading subset. oTDH is a price-independent signal of current uninterrupted collector holding duration.

  "properties": {
    "limit": {
      "type": "integer",

}
    arguments 12 lines
  • get_artist_otdh reads unknown never probed

    Get one artist's oTDH rank, score, collector breadth, raw collector-days, project count, and snapshot metadata by AB5D artist slug.

    mcp-tool

  "additionalProperties": false
}
    arguments 5 lines
  • get_artist_collector_tdh reads unknown never probed

    Get one artist-specific collector TDH register by AB5D artist slug. Collector rows are paginated because large Raster-indexed oeuvres can contain thousands of current addresses.

    {
  "type": "object",
  "required": [
    "slug"
  ],
  "properties": {
    "slug": {

      "type": "integer",
      "default": 0,
      "minimum": 0

}
    arguments 24 lines
  • list_open_bounties reads unknown never probed

    List every AB5D bounty that is currently open for claim, including reward, eligibility, claim route, submission route, protocol, and acceptance command. Only returned tasks are current offers.

    mcp-tool

    {
  "type": "object",
  "required": [
    "task_id"
  ],
  "properties": {
    "task_id": {
      "type": "string",
      "description": "Task identifier from list_open_bounties, e.g. 'MA-CAL-CT-01'"
    }

_ try it over mcp 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 knowoff the mcp door
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.
