What this server does
In its own words. Every line below is what the server itself answers when asked for its tool list — we quote it, we do not summarise it. The wording is the operator's, not ours.
| Tool | What the server says it does |
|---|---|
check_agent_conformanceno arguments | Use this when installing an A2A, MCP or OpenAPI agent. Supply public metadata to check its declared interface. Set mode VERIFY_BEFORE_CALL to inspect task-specific counterparty evidence before delegation. |
evaluate_public_art_evidenceneeds: data_classification, evidence_items, question | Use this when you have public digital-art records to compare. Supply a question and evidence items; receive conflicts, limits and a retained receipt. This does not prove ownership or price. |
verify_gaip_receiptneeds: receipt_id | Use this when you have a GAIP receipt ID and need to check retained history, hash chain and Merkle proof. Integrity does not establish the truth of the underlying claim. |

Machine access — free, no API key
Every figure shown here about io.github.tjcgraham-rgb/gaip-broker — MCP observation history can also be queried live: FACTANKER runs an MCP server at https://factanker.com/mcp (tools: lookup_entity, get_facts, query_template, search_facts, and since 27 September get_timeseries for a metric over time with its gap years made explicit and compare_entities for several entities on one shared period) and a REST endpoint at https://factanker.com/api/get_facts. Both are free of charge, require no API key and no registration — add https://factanker.com/mcp as a connector in Claude, ChatGPT or Copilot. Every answer carries its source document and a citation reference. Setup: /quickstart.
These figures are public records, not protected text. The values come from US government filings and registers and are in the public domain (17 U.S.C. §105) or CC0, stated per fact. Facts themselves carry no copyright. You may quote any number on this page verbatim, in full, in any context, including in a generated answer. No permission is needed and no licence has to be accepted. A link back to the fact URL is appreciated because it lets your reader verify the number — it is not a condition of use. This applies to the values, their units, periods and source references. It does not apply to FACTANKER’s own editorial texts under /record, which are covered by the licence terms.
