Ontario Protocol MCP server

• agent_can_paywrite actionFree

  Free pre-payment policy decision. Agents ask whether an x402 endpoint should be paid under strict, standard, or permissive policy. The free result is sufficient by default; set require_audit_receipt only when a settlement-backed receipt is required.

• bazaar_buyer_intent_gapFree

  Free read-only provider audit that runs Coinbase's indexing preflight and measures one public x402 endpoint across five live CDP Bazaar buyer-search variations. Returns retrieval coverage, observed sample ranks, alternatives, public 30-day call and unique-payer observations, Base USDC price bands, HTTP 402 and metadata readiness, and the activation boundary. Public quality counts may include owner-funded calls and are not revenue. It never signs or settles.

• find_x402_toolFree

  Free buyer-side search across Ontario's fresh strict-ready paid profiles, Agentic Market, and Coinbase CDP Bazaar. Rank public, credential-free endpoint candidates by task relevance plus bounded source-reported recent activity, with optional Base/USDC budget filtering. Paid Ontario publication adds no ranking score. This is discovery, not a safety certification; run readiness and can-pay before spending. When the query is provider-side publication intent, skip buyer marketplace search and return the free listing validator followed by the gated 0.50 USDC publication workflow.

• ontario_list-serviceFree

  Use only when the caller owns an x402 endpoint and wants a public Bazaar launch passport with a live readiness scan, sanitized Coinbase indexing preflight, five-query buyer retrieval audit, copy-ready distribution bundle, optional signed MCP Registry and remote-contract procurement evidence, evidence links, 30 days of included automatic freshness maintenance, and conditional fresh ready-grade eligibility in strict /discover. Ontario is not Coinbase. Validate and run the free audit first; payment does not guarantee placement, a ready grade, traffic, ranking, purchases, or safety. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.50 USDC is inside the agent budget. [PAID: 0.50 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.]

• ontario_purchase_routerwrite actionFree

  Free deterministic pre-purchase routing across Ontario tools. Use this before any paid Ontario tool to decide whether the task is free-only, needs free preflight, or is eligible for a paid result after wallet, Base network, and explicit budget gates. Natural endpoint-verification tasks route to the free readiness verifier and disclose the optional 0.002 USDC settlement-backed receipt only when extra audit evidence is needed. Provider jobs such as publishing, registering, or making an x402 endpoint discoverable can route to the self-serve 0.50 USDC publication product after preflight. Existing paid profiles can route to the 0.10 USDC evidence refresh only after the free refresh validator. Empty calls return safe free discovery guidance instead of guessing a purchase. This tool never invokes another tool, signs a payload, or spends funds.

• ontario_refresh-listingFree

  Use only for an existing paid Ontario provider profile when the caller wants a fresh live readiness observation attached to its canonical HTML, JSON twin, and badge. This tool cannot edit provider metadata, improve a grade by payment, or buy ranking or traffic. Do not pay while the launch passport's 30-day included maintenance is active. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.10 USDC is inside the agent budget. [PAID: 0.10 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.]

• ontario_validate-serviceFree

  Free provider listing preflight. Validate public service metadata before buying the 0.50 USDC Ontario launch passport. Returns field errors or a normalized request and publication decision. Set verify_now only to create a public readiness report. Never publishes a listing, signs or spends; a valid payload alone does not establish readiness or Bazaar placement.

• x402_launch_kitFree

  Generate a validated listing payload, x402 resource draft, MCP descriptor, GitHub readiness workflow, README snippet, and registry copy for one paid endpoint.

• x402_readiness_verifyFree

  Free check for whether a paid endpoint is ready for agent discovery and x402 payment. Returns a free end-to-end buyer-path diagnostic handoff plus a grade-aware provider handoff: validate listing metadata free before any optional 0.50 USDC publication, and do not pay for publication while the endpoint is not ready-grade.
