AB[500] research and bounties is an MCP server with 10 tools an agent can call, among them get_artist_collector_tdh, get_artist_otdh, get_bounty. It answers at https://ab5d.xyz/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Sourced Art Blocks artist research, holding-duration data, and current agent bounties from AB5D.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_artist_collector_tdh | 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. Inputs: slug, offset, limit |
get_artist_otdh | Get one artist's oTDH rank, score, collector breadth, raw collector-days, project count, and snapshot metadata by AB5D artist slug. Inputs: slug |
get_bounty | Get one AB5D bounty task by identifier, including its current status and operational routes. Do not begin work unless the returned status is open. Inputs: task_id |
get_dossier | 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. Inputs: slug |
get_otdh_methodology | Get the definition, formulas, full-universe coverage, limitations, discussion URL, and snapshot metadata for AB5D's artist-level Oeuvre Total Days Held metric. |
list_artist_collector_tdh | List all 308 artist-specific collector TDH dashboard records, including each metric label, route, data URL and verified or pending source status. |
list_artist_otdh | 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. Inputs: limit |
list_dossiers | List every published AB[500] artist dossier (name, slug, subtitle, editions, tier, updated date). Start here to discover which artists have a biography available. |
list_open_bounties | 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. |
search_artists | 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. Inputs: query |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://ab5d.xyz/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.maxand98. Endpoint host: ab5d.xyz. ARD identifier: urn:air:io.github.maxand98:mcp:ab500-research.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
