get_lineage
Fetch the maintainer-approved cross-network subnet lineage: which testnet subnets have graduated to mainnet (mainnet ↔ testnet pairs with the match evidence), plus any flagged broken links. Use it to map a mainnet subnet to its testnet counterpart or vice versa. Mirrors GET /api/v1/lineage. Field...

The rule that runs get_lineage 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_lineage, this is the rule to start with:
get_lineage 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_lineage call is checked against it from then on.
Questions about get_lineage
Fetch the maintainer-approved cross-network subnet lineage: which testnet subnets have graduated to mainnet (mainnet ↔ testnet pairs with the match evidence), plus any flagged broken links.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches metagraphed — Bittensor subnet operational registry. Nothing to install.
get_lineage is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_lineage rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
