# check_relay_health Check the sponsor relay health and nonce status. Use this tool for operator diagnostics around relay-owned sponsor state. It will: - Check relay availability - Inspect sponsor address nonce state - Detect nonce gaps that block transactions - Detect mempool desync (confirmed nonce far behind mempool nonce) - List stuck transactions with txid, nonce, and how long they have been pending - Report mempool congestion This tool does not redefine caller-facing x402 payment states. Use paymentId polling for payment lifecycle truth; use this output only as backup diagnostics. Agent View of the PolicyLayer registry record for `check_relay_health`.

It performs queries and inspections only, with no data creation, modification, deletion, or execution of transactions. The tool is designed for operator diagnostics and troubleshooting, not for taking actions that would change system state. From the tool's own definition: "Tool checks relay health status and nonce state without modifying any data. Specific actions listed are: 'Check relay availability', 'Inspect sponsor address nonce state', 'Detect nonce gaps', 'Detect mempool desync', 'List stuck transactions', 'Report…" ## Use case AI agents call check_relay_health to retrieve information from Aibtc without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Aibtc: ```json { "version": "1", "default": "deny", "tools": { "check_relay_health": {} } } ``` ## Other tools on Aibtc (357) - `bitflow_cancel_order` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/bitflow-cancel-order.md - `bounty_cancel` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/bounty-cancel.md - `credentials_delete` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/credentials-delete.md - `delete_hiro_api_key` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/delete-hiro-api-key.md - `identity_unset_wallet` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/identity-unset-wallet.md - `jingswap_cancel_cycle` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/jingswap-cancel-cycle.md - `jingswap_cancel_sbtc` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/jingswap-cancel-sbtc.md - `lightning_lock` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/lightning-lock.md - `ordinals_p2p_cancel` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/ordinals-p2p-cancel.md - `pillar_direct_revoke_fast_pool` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/pillar-direct-revoke-fast-pool.md - `reputation_revoke_feedback` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/reputation-revoke-feedback.md - `stackspot_cancel_pot` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/stackspot-cancel-pot.md - `wallet_delete` — Destructive — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/wallet-delete.md - `broadcast_transaction` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/broadcast-transaction.md - `btc_sign_message` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/btc-sign-message.md - `call_contract` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/call-contract.md - `deploy_contract` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/deploy-contract.md - `dual_stacking_opt_out` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/dual-stacking-opt-out.md - `inference_check_provider` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/inference-check-provider.md - `inscribe_child_reveal` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/inscribe-child-reveal.md - `inscribe_reveal` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/inscribe-reveal.md - `jingswap_close_deposits` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/jingswap-close-deposits.md - `jingswap_settle_with_refresh` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/jingswap-settle-with-refresh.md - `lightning_unlock` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/lightning-unlock.md - `news_publisher_compile_brief` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/news-publisher-compile-brief.md - `nonce_heal` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/nonce-heal.md - `nostr_sign_event` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/nostr-sign-event.md - `pillar_connect` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/pillar-connect.md - `pillar_key_generate` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/pillar-key-generate.md - `pillar_key_lock` — Execute — https://policylayer.com/tools/io-github-aibtcdev-mcp-server/pillar-key-lock.md - …and 327 more: https://policylayer.com/tools/io-github-aibtcdev-mcp-server.md ## For agents This record is a snapshot.
