Hive Flag
A feature flag service built for the Hive agent network that lets you toggle behavior, ramp rollouts by percentage, or target specific DIDs without redeploying agents. Exposes six MCP tools including flag_eval for runtime checks, flag_create and flag_update for configuration, and flag_list for discovery. Uses DID-based ownership, sticky percentage rollouts via SHA256 bucketing, and x402 payment verification with USDC on Base L2. Paid calls like flag_eval cost half a mill, free reads for listing and describing flags. Reach for this when you need to kill a runaway agent behavior in production, canary a new tool to 10% of your fleet, or A/B test prompts across DIDs. Stores flags in SQLite, verifies payments on-chain by reading Base receipts.
