get_subnet_lifecycle
Fetch one subnet's append-only registration/deregistration timeline, newest first. Entries with predates_capture=true are older than detection and carry a null block_number — that is a real answer, not a missing one. Page with limit (1-1000, default 100) / offset.

What get_subnet_lifecycle does on metagraphed — Bittensor subnet operational registry
AI agents call get_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 100 when omitted. The response reports the limit actually applied. |
netuid | integer | Yes | Subnet id (netuid), 0-65535. 0 is the root subnet, which is special: it has no AMM pool and is emission-ineligible. |
offset | integer | — | Rows to skip before the first returned row (0-1000000). Defaults to 0; a non-numeric value resolves to 0 and the response reports it. |
context | string | Yes | The user's goal, briefly. Analytics only; does not affect the result. |
llm_model | string | — | Your model ID if known; omit otherwise. Analytics only. |
conversation_id | string | — | Reuse the conversation_id returned by this server; omit on the first call. Analytics only. |
Parameters from the server's own tool schema.

Attacks that exploit this kind of access
The rule that runs get_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_subnet_lifecycle, this is the rule to start with:
get_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_subnet_lifecycle call is checked against it from then on.
