What it can do
| Tool | What it says it does |
|---|---|
a2a.resolve_card | Discover and inspect an external Agent-to-Agent (A2A) node by domain or URL. Fetches .well-known/agent-card.json, validates protocol compatibility, checks for a2a-x402 and AP2 payment extensions, and extracts callable skills with pricing. |
city.check | Is this US address licensed / flagged / showing open violations? One city.check ($0.01 USDC, x402 on Base) returns verdict, summary, dates, and source_url. Unpaid → PaymentRequired; pay via _meta['x402/payment']. Prefer city.sample first. |
city.list | List US cities with paid_url and free sample_url for property compliance. Start here — each paid lookup is $0.01 USDC and returns a normalized verdict plus source link, not raw portal JSON. Then city.sample, then city.check. |
city.sample | Free fixed-address preview of paid property-check JSON (verdict, summary, schema). Use before city.check to validate parsing without spending $0.01 USDC. |
commerce.activate_pro | Verify a Pro-tier x402 payment and unlock Pro quota limits for the agent. MCP-native: call without payment to receive x402 requirements in the tool result, then retry with _meta['x402/payment'] (@x402/mcp client). Legacy: pass PAYMENT-SIGNATURE + PAYMENT-REQUIRED after commerce.pro_requirements. |
commerce.credits_requirements | Build x402 payment requirements to buy a pack of per-use MCP tool credits. Next: pay those terms, then commerce.purchase_credits with the signature. |
commerce.pro_requirements | Build x402 payment requirements to purchase the Pro quota tier. Next: pay those terms, then commerce.activate_pro with the signature. |
commerce.purchase_credits | Verify an x402 payment and add per-use tool credits to the agent. MCP-native: call without payment for x402 requirements, then retry with _meta['x402/payment']. Legacy: PAYMENT-SIGNATURE + PAYMENT-REQUIRED after commerce.credits_requirements. |
ops.metrics | Get host OS telemetry: CPU, memory, swap, disk, network, and an ok/warn/critical health verdict. Call to diagnose this MCP host; set include_processes=true for top memory processes. |
pulse.base | Get live Base Network Pulse: base fee, EIP-1559 projection, utilization, USD settlement cost, verdict. Call before settling on Base when you need a settle-now vs hold recommendation. |
swarm.research | Run the swarm agency: compose a research product from free inputs and list it for resale. Pass allow_paid_inputs=true only when buying upstream x402 services is intended. |
swarm.revenue | Get swarm composite economics: spend, composite sales, LTV:CAC, margins, per-source scores. total_revenue_usdc is swarm listings only; storefront.revenue_usdc is the full settled ledger. Call after swarm.research or swarm.settle to inspect realized economics. |
swarm.settle | Verify and settle a buyer's x402 payment for a listed composite product and record revenue. Call with product_id plus PAYMENT-SIGNATURE after the buyer pays. |
x402.agent_card | Return the A2A Protocol v1.0 Agent ID Card and MCP server card. Optional target_id filters to a skill id, name, or tag. |
x402.build_seller | Build seller-side x402 payment requirements for your own HTTP resource. Pass resource_url plus discovery_* fields to catalog the endpoint in Bazaar. |
x402.discover | Discover paid HTTP APIs in the x402 Bazaar via the facilitator catalog. Call this first to find a resource URL, then x402.probe and x402.pay_and_fetch. |
x402.networks | List supported settlement networks, facilitators, and x402 v2 header names. Call when choosing a preferred_network for x402.pay_and_fetch or x402.build_seller. |
x402.pay_and_fetch | Pay USDC via x402 and fetch a protected HTTP resource in one call. Requires EVM_PRIVATE_KEY on this host; otherwise use x402.probe for a no-spend 402. |
x402.policy_check | Decode a caller-supplied merchant PAYMENT-REQUIRED header and evaluate each accepts[] option against an explicit buyer policy (networks, pay_to, assets, max atomic amount). Does not fetch merchant URLs or settle the inspected purchase. Unpaid → PaymentRequired for this server's analysis fee; pay… |
x402.probe | Probe a URL for HTTP 402 PAYMENT-REQUIRED terms using the x402 client SDK. Use before x402.pay_and_fetch to inspect price, network, and payTo without spending. |
x402.verify | Verify an x402 PAYMENT-SIGNATURE against PAYMENT-REQUIRED terms via the facilitator. Call after a buyer presents a signature and before releasing paid content. |
