Screens a flat exposure list (name, sector, amount) for credit concentration: the top-N single-name exposures by amount, a per-sector rollup, single-name and sector Herfindahl-Hirschman Index (HHI, 0–10000 scale), and a breach list against limit percentages you declare. Concentration limits are your own institution's risk-appetite policy, not a fixed regulatory number — nothing is baked in.

Run the AINumbers MCP tool `check_credit_concentration_topn_sector`. Task: Credit-concentration screen over a flat exposure list (name, sector, amount): returns the top-N single-name exposures by amount, a per-sector rollup, single-name and sector Herfindahl-Hirschman Index (0-10000 scale), and a breach list against caller-declared single-name and sector limit percentages.
Synthetic sample input (policy_parameters): {"exposures":[{"name":"A","sector":"Retail","amount":1200000},{"name":"B","sector":"Retail","amount":800000},{"name":"C","sector":"Energy","amount":2500000},{"name":"D","sector":"Energy","amount":500000},{"name":"E","sector":"Tech","amount":400000},{"name":"F","sector":"Healthcare","amount":600000}],"top_n":3}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the returned execution_hash.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
