The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_offer open 2h ago

    Create or refresh a one-hour signed bearer offer for a chosen skill, bundle, audit, or fix. Do not call this after a paid search_fixes result or an unpaid get_fix/get_skill result because those responses already include both payment rails. Choose USDC for Base Pay or ETH for exact wei; with no product arguments, this returns the general settlement document.

  • list_merch open 2h ago

    Browse the KnownFix Merch Store. Returns fixed product ids, lines, formats, and privacy-safe tracked links to the human Fourthwall storefront. Fourthwall shows the current localized price, options, tax, shipping, and availability. This tool does not place an order or collect checkout data.

  • list_skills open 2h ago

    Compare premium skills and multi-fix bundles. Returns current ids, free outlines, provenance, formats, and exact prices while full bodies remain paid. Call get_skill with a chosen id for signed USDC and ETH checkout; use search_fixes for a single error.

    mcp-tool

    {
  "type": "object",

}
    arguments 4 lines
  • order_service unknown never probed

    Create a private ticket and signed Base USDC/ETH checkout for one published professional service. Accepts public HTTPS websites or public GitHub repositories only. Never include credentials, tokens, secrets, private repository URLs, or confidential data. The returned svc_ ticket is shown once and is the only report-retrieval credential.

    arguments 39 lines
  • search_fixes unknown never probed

    Use this first for an exact error or distinctive symptom. Returns up to three confident ranked matches. A free top match includes the full fix. A paid top match includes a free diagnosis, confidence and compatibility, dollar price, signed USDC/Base Pay and exact-ETH rails, and one pay-and-redeem action; do not call get_offer. Use list_catalog to browse, get_fix only with a known id or payment proof, and request_fix only after an honest miss.

    mcp-tool

    {
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "query": {

    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • request_fix unknown never probed

    Ask for a fix this store does not have yet. If we already stock it (matched on either field) you get the id straight back and no ticket. Otherwise you get a ticket; when we stock THAT fix, check_request returns it to you FREE, once. A ticket only ever redeems a fix created after the request: fixes that already existed when you asked are not free, whatever the request said. No contact details are collected. Set publish: true ONLY if the text may appear on a public wanted board — never include secrets, tokens, internal hostnames, or file paths.

  "type": "object",

    }
  }
}
    arguments 20 lines
  • check_request unknown never probed

    Check a private ticket from request_fix. Returns pending, declined, not-eligible, redeemed, or the full fix free once an eligible new fix is stocked. This call may atomically consume the ticket's one-time delivery, so save the returned body. Use get_fix when you already have a catalog id; do not create another request while this ticket is pending.

    mcp-tool

    {
  "type": "object",
  "required": [
    "ticket"
  ],
  "properties": {
    "ticket": {

  },

}
    arguments 13 lines
  • list_catalog unknown never probed

    Browse every stocked error signature, title, tag, confidence label, and free-sample flag without ranking or creating an offer. Use search_fixes instead when diagnosing a specific error; it returns the best match and any purchase-ready checkout.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • list_services unknown never probed

    Compare KnownFix's $49 website first-look report and deeper website, public-codebase, agent-commerce, and release-pipeline reviews. Returns bounded scope, deliverables, delivery time, limitations, sample-report links where available, and exact prices. Call order_service only after choosing a service and confirming authority over the public target.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • check_service_order unknown never probed

    Check a private service order by its svc_ ticket. With paymentTx and paymentOffer, atomically confirms exactly one matching Base payment and moves the order into review. Without payment fields, returns current status; once complete, it returns the private Markdown report and SHA-256 digest. Keep the ticket and signed offer private.

    arguments 23 lines
  • audit_endpoint unknown never probed

    Readiness audit of any agent-facing URL: MCP handshake, CORS, discovery docs (llms.txt, mcp.json), and payment-offer behaviour. First call with url alone for the FREE grade and failing-check list. For the full findings and remediations, call get_offer with productType "audit" and productId "conformance-report", pay, then call audit_endpoint again with the same url plus paymentTx and paymentOffer. This tool both previews and redeems the paid report; no separate delivery tool is needed.

    }
  }
}
    arguments 21 lines
  • audit_theme unknown never probed

    Run a read-only theme audit on a public HTTP(S) page, free in full. Fetches but never modifies the page, then checks inline style CSS for brace errors, token gaps, incomplete dark themes, missing body backgrounds, and WCAG body-text contrast. External stylesheets are counted but not fetched. Use audit_endpoint instead for MCP, CORS, discovery, and payment readiness.

    }
  },
  "additionalProperties": false
}
    arguments 14 lines
  • report_checkout_blocker unknown never probed

    Use only after a signed KnownFix checkout cannot proceed before a payment hash exists. Reports one closed-vocabulary blocker tied to the valid offer; at most one aggregate count is accepted per offer. No wallet address, token, transaction hash, query, or free-form text is published. Do not call after payment; redeem with get_fix, get_skill, or audit_endpoint instead.

  • get_fix unknown never probed

    Get or redeem a fix after search_fixes or list_catalog identifies the id. Free samples return immediately. For a paid fix, call with the id alone to receive a free diagnosis preview, confidence and compatibility, dollar price, signed Base Pay USDC and exact-ETH offers, and one pay-and-redeem action; then call once more with the matching paymentTx and private paymentOffer. Never pay again merely because an existing proof is pending or denied.

  • get_skill unknown never probed

    Get or redeem a premium skill or multi-fix bundle after choosing with list_skills. Call with the id alone to receive the free outline, dollar price, signed Base Pay USDC and exact-ETH offers, and one pay-and-redeem action. After payment, call once more with the matching paymentTx and private paymentOffer for the complete SKILL.md or assembled bundle decision tree, fix bodies, verification commands, update guidance, and sources. Do not use this for individual fixes; call get_fix instead. Never pay again merely because an existing proof is pending or denied.

    arguments 22 lines
  • submit_fix unknown never probed

    Offer a fix for the catalog. Submissions are reviewed by the operator before listing; include a reproduction so the fix can be verified rather than trusted. Returns a private submissionId; save it and call check_submission for pending, accepted, declined, or cataloged status. Submitted text and contributor details are never returned by the status tool. Revenue-sharing for accepted contributions is planned, not yet live.

  • check_submission unknown never probed

    Check the private submissionId returned by submit_fix. Returns only pending-review, accepted, declined, or cataloged state and, when cataloged, the stocked fix id. It never returns submitted text or contributor details and creates no side effects. Use get_fix with catalogId when cataloged; do not resubmit merely because review is pending.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

[![measured by brick.blue](https://brick.blue/api/v1/agents/b35b226dca9a2dc3/badge.svg)](https://brick.blue/agent/b35b226dca9a2dc3)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
