WHAT IT DOES

What get_chain_signers does on metagraphed — Bittensor subnet operational registry

AI agents call get_chain_signers 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.

Parameter	Type	Required	Description
`sort`	string	—	Column to rank the result by; pair with `order` for direction. Options are per-tool; see this parameter's enum. Defaults to tx_count.
`limit`	integer	—	Maximum rows to return (1-100). Defaults to 50 when omitted. The response reports the limit actually applied.
`window`	string	—	Trailing time window to aggregate over, ending at the latest data point rather than a calendar boundary. Options are per-tool: `7d`, `30d`. Defaults to 7d.
`context`	string	—	Optional: the user's goal, briefly. Analytics only; does not affect the result.
`call_module`	string	—	Restrict to one pallet, by its runtime name (`SubtensorModule`). Case-sensitive.

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs get_chain_signers safely

PolicyLayer is an MCP gateway: it sits between your AI agents and metagraphed — Bittensor subnet operational registry, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_chain_signers, this is the rule to start with:

get_chain_signers Allowed

get_chain_signers is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_chain_signers": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect metagraphed — Bittensor subnet operational registry, apply this rule, and every get_chain_signers call is checked against it from then on.
