  "instructions": "    UCP Checker — read-only.\n\n    This server answers two questions: **is this store agent-ready, and which\n    verified stores match what I am looking for?** Every tool reads public,\n    observed state. Nothing here writes to a merchant, creates a cart, or\n    produces a checkout URL. Once you have chosen a store, transact with that\n    store directly.\n\n    ## What is UCP?\n    UCP is a machine-readable manifest at `/.well-known/ucp` that exposes commerce\n    capabilities to AI agents — what a store supports, how to reach it, and how to\n    pay. UCP Checker observes those manifests continuously and publishes what it\n    finds.\n\n    ## Tools\n\n    ### check-domain\n    Is this store agent-ready? Returns status, spec version, capabilities, latency\n    and AI bot policies for any domain, observed — not self-reported.\n\n    ### list-categories\n    Categories for the deeply audited subset of verified stores, with counts. A way\n    to browse, not the whole index.\n\n    ### list-stores\n    Every verified UCP storefront, best-evidenced first, filterable by platform. Each\n    store says what we have observed: transactable, catalogued, resolvable or declared.\n\n    ### search-all\n    Search product catalogs across the verified stores whose observed catalogue\n    matches the query. Returns results grouped by store. Use when the user has no\n    store in mind.\n    Results are ranked by lexical relevance only — relevance is not endorsement,\n    and the conformance record is linked rather than asserted. When nothing\n    matches well enough it answers \"No strong match\" and searches no one:\n    take that as a cue to check a store you know, not to reword and retry.\n\n    ### search-catalog\n    Search one store's declared catalog.\n\n    ### get-product-details\n    Full detail for one product in a store's declared catalog, including variants.\n\n    ### search-policies\n    A store's return, shipping, refund, privacy and terms policies. Use to check\n    trust signals before recommending a merchant.\n\n    ### discover-store\n    Connect to a store's own MCP endpoint and list the tools it exposes. Use this\n    to find out what a store lets an agent do — then talk to the store directly.\n\n    ## Resolution flow\n    1. `search-all` or `list-stores` — which verified stores match\n    2. `list-categories` — optional: browse the deeply audited subset by category\n    3. `check-domain` — confirm the store's current observed state\n    4. `search-policies` — check the trust signals\n    5. `discover-store` — see what the store itself offers, and go there to buy\n\n    ## What a negative answer means\n    Information, not permission. A store missing from the index, or returning\n    `not_detected`, has not been observed by us — it is not barred to you. If a\n    store matters to your task, try `discover-store` or connect to it directly\n    regardless of what we report.\n\n    Results carry an evidence band saying how much we have actually seen:\n    `transactable` (checkout declared and catalogue read) · `catalogued`\n    (catalogue read) · `resolvable` (endpoint resolves, not yet probed) ·\n    `declared` (valid manifest, nothing observed beyond it). A low band means\n    we have looked less, not that the store is worse.\n\n    ## Not available here\n    Cart, checkout, order placement, and merchant selection. Use the merchant's own\n    endpoint for those — `discover-store` lists what it exposes.\n\n    ## Access tiers\n    Rate limits scale with how strongly your agent identifies itself:\n    - **Anonymous** (no credentials): every tool, at the lowest limits.\n    - **Signed** (RFC 9421 HTTP Message Signatures; publish your keys at a\n      `Signature-Agent` host's `/.well-known/http-message-signatures-directory`):\n      higher limits.\n    - **Token** (`Authorization: Bearer {key}`, issued by UCP Checker): highest.\n\n    ## Status meanings\n    - **verified**: valid UCP manifest found with the required fields\n    - **not_detected**: no manifest at /.well-known/ucp (HTTP 404)\n    - **invalid**: manifest exists but is missing required fields or invalid JSON\n    - **blocked**: access denied (HTTP 403/401 or robots.txt disallow)\n    - **unreachable**: connection failed (timeout, DNS, SSL error)",
