WHAT IT DOES

What news_claim_beat does on Aibtc

AI agents use news_claim_beat to create or update resources in Aibtc, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aibtc environment.

RISK

Why news_claim_beat is rated Medium

This tool creates or joins beats, which are write operations that modify state on the aibtc.news platform. While it requires wallet authentication and uses cryptographic signing (BIP-322), the core action is data creation/modification rather than deletion or financial transaction. The 'Create or join' language indicates state-mutating operations.

From the tool's definition 'Create or join a beat on aibtc.news' — the tool creates new beats or modifies membership state by joining existing ones. It modifies data on a remote service (the news API).

RECOMMENDED RULE

The rule that runs news_claim_beat safely

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

news_claim_beat Rate-limited

news_claim_beat stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about news_claim_beat

What does the news_claim_beat tool do? +

Create or join a beat on aibtc.news. Requires an unlocked wallet with a P2WPKH (bc1q) BTC address.

Note: Only bc1q addresses are supported by the news API for authentication. Taproot (bc1p) addresses cannot claim beats. Use news_list_beats first to see existing beats and avoid duplicates. Retired beat slugs return 410 Gone. Fields: - slug: beat slug, lowercase with hyphens — active beats:.
