What get_chain_subnet_lifecycle does on metagraphed — Bittensor subnet operational registry
AI agents call get_chain_subnet_lifecycle 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 |
|---|---|---|---|
limit | integer | — | Maximum rows to return (1-1000). 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`, `90d`, `1y`, `all`. |
context | string | — | Optional: the user's goal, briefly. Analytics only; does not affect the result. |

Attacks that exploit this kind of access
The rule that runs get_chain_subnet_lifecycle 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_subnet_lifecycle, this is the rule to start with:
get_chain_subnet_lifecycle is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect metagraphed — Bittensor subnet operational registry, apply this rule, and every get_chain_subnet_lifecycle call is checked against it from then on.

It is categorised as a Read tool in the metagraphed — Bittensor subnet operational registry MCP Server, which means it retrieves data without modifying state.
get_chain_subnet_lifecycle accepts 3 parameters: limit, window, context. The full parameter table on this page comes from the server's own tool schema.
Register the metagraphed — Bittensor subnet operational registry MCP server in PolicyLayer and add a rule for get_chain_subnet_lifecycle: allow, deny, rate-limit, or require approval.
