# get_chain_holders Fetch EVERY subnet ranked by how concentrated its alpha OWNERSHIP is (#9607) -- per subnet the distinct holder count, measured alpha total, top1/top5/top10/top20 shares and the largest holder's coldkey (an ss58 address). The cross-subnet companion to get_subnet_holders, which answers this one subnet at a time; use this to find where ownership is concentrated across the network in one call. NOT the same as get_chain_concentration, which computes Gini/HHI/Nakamoto off registered UIDs' stake and therefore cannot see alpha held on hotkeys with no UID -- the two disagree by design. IMPORTANT: alpha is NEVER summed across subnets, because each subnet's alpha is a different token; total_alpha is per subnet and the network block carries only counts plus the MEDIAN top-1 share. To compare holdings across subnets you must price each through its own alpha_price_tao -- get_top_holders already does that. sort is one of top1_share (default), top5_share, top10_share, top20_share, holder_count, total_alpha; a subnet whose share could not be computed sorts LAST rather than reading as the least concentrated. limit caps the rows (default 20, max 512), above the subnet count so ranking the whole network is one call. An empty subnets list is NOT evidence that nobody holds alpha -- check degraded.reason first. Mainnet only. Mirrors GET /api/v1/chain/holders.

HTML page: https://policylayer.com/tools/io-github-jsonbored-metagraphed/get-chain-holders ## Facts - Tool: `get_chain_holders` - Server: metagraphed — Bittensor subnet operational registry (`https://api.metagraph.sh/mcp`) — https://policylayer.com/tools/io-github-jsonbored-metagraphed.md - Homepage: https://github.com/JSONbored/metagraphed - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: no - Parameters: 3 - Recommended policy verdict: Allowed ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `sort` | string | no | Column to rank the result by; pair with `order` for direction. Options are per-tool; see this parameter's enum. Defaults to top1_share. | | `limit` | integer | no | Maximum rows to return (1-512). Defaults to 20 when omitted. The response reports the limit actually applied. | | `context` | string | no | Optional: the user's goal, briefly. Analytics only; does not affect the result. | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_chain_holders", "arguments": {} } } ``` ## Why get_chain_holders is rated Low Tool retrieves and aggregates blockchain holder data without modification, deletion, or execution effects. From the tool's own definition: "Fetch EVERY subnet ranked by...holder count, measured alpha total, top1/top5/top10 shares." Risk signals: Bulk/mass operation — affects multiple targets ## Use case AI agents call get_chain_holders to retrieve information from metagraphed — Bittensor subnet operational registry without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
