# Capital Markets Knowledge Graph — Germany node door
Operator: Allooloo Technologies Corp. Read-only MCP server, Streamable HTTP at https://mcp.de-cm-kg.ai/mcp, JSON-RPC 2.0, no authentication. Public-record only: no prices, quotes or licensed market data.
Scope: Xetra common shares in the German product groups (DAX, MDAX, SDAX, TecDAX, DEUTSCHLAND). 420 records, 1703 dated, URL-carrying disclosure events over 12 months for the corporate issuers.
Tools: resolve_issuer (ticker, ISIN or LEI -> record summary), get_record (full Capital Markets Record with per-field source_url, read_by and state), list_events_since (paged events since a date), list_aliases (sourced trade and former names), list_nodes (the twelve market nodes, which are live, record counts).
Identifiers: ticker with or without exchange (SAP, XETRA:SAP, SAP.DE, ETR:SAP), ISIN, LEI. An ambiguous ticker returns every match; the door never guesses.
Record spec: CMR v0 (cm-record.org, draft). Blank stays blank: a field with no value is present with value null and its reason. No signature key exists yet; it is omitted, not stubbed.
GET paths: / (this door), /facts.json, /llms.txt, /nodes.json, /record/<EXCHANGE>/<TICKER> (node hosts) or /record/<node>/<EXCHANGE>/<TICKER> (any host), /events/… likewise with ?since=YYYY-MM-DD&cursor=0&limit=50. Exchanges: XETRA.
