api record

Proofsource measures how AI answer engines (ChatGPT, Perplexity, Claude, Google AI Overviews and others) answer a brand's buyer questions: whether they mention the brand, which competitors they recommend instead, which sources they cite, and whether the fixes you ship move those numbers. Start with list_brands (every other tool takes its brand_id; it may be omitted when the workspace tracks one brand). Is my brand mentioned in AI answers: get_visibility. Who does AI recommend instead of me: get_competitors. Which sources do AI answers cite: get_citations. What changed: get_changes. What to…

  • list_brands unknown never probed

    The brands this Proofsource workspace tracks in AI answers, with ids and websites. Call first; every other tool takes a brand_id.

  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • list_topics unknown never probed

    The topics and buyer questions Proofsource asks ChatGPT, Perplexity, Claude and Google AI for a brand. Gives the topic_id create_prompt needs.

  • get_visibility unknown never probed

    How often ChatGPT, Perplexity, Claude and Google AI mention the brand when buyers ask about its category. by=engine (default): mention rate, share of voice, average position, citation share and sentiment per engine, with the change from the previous period. by=question: each buyer question's mention rate and rank.

  • get_citations unknown never probed

    The websites AI answers cite for the brand's buyer questions, ranked by share of citations and by how many answers cite them, and where the brand's own site ranks.

    arguments 29 lines
  • get_changes unknown never probed

    What moved over the window: the daily mention-rate trend, how much the engines' answers changed, notable changes on competitors' websites, and new pages about the category.

    arguments 16 lines
  • list_fix_opportunities unknown never probed

    The gaps that keep AI engines from citing or recommending the brand, each with its evidence and the suggested fix. Gives the gap_id mark_fix_shipped needs.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "brand_id": {
      "type": "string",

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

    Each fix marked shipped for the brand with its mention rate before and after and a verdict: moved (beyond normal answer churn), within_noise, or awaiting_samples. Fixes marked "Not a fix" are left out; auto-detected page changes carry source auto_detected.

    mcp-tool

    {

    "limit": {
      "type": "integer",

}
    arguments 20 lines
  • create_prompt unknown never probed

    Adds a buyer question to a topic so Proofsource asks it on every engine in the plan from the next run. Counts toward the plan's question limit. Calling again with the same text returns the existing question, never a duplicate.

    mcp-tool

    {
  "type": "object",

    "topic_id",
    "text"
  ],
  "properties": {

  "additionalProperties": false
}
    arguments 30 lines
  • mark_fix_shipped unknown never probed

    Records that a fix shipped, against a gap_id from list_fix_opportunities or a published content_draft_id, so get_fix_verification can measure whether it moved the brand's mention rate. Calling again with the same fix and description returns the existing record.

    mcp-tool

    {
  "type": "object",
  "required": [
    "description"
  ],
  "properties": {
    "gap_id": {

    },
    "shipped_at": {
      "type": "string",
      "description": "When it shipped: RFC 3339 timestamp or YYYY-MM-DD. Default now."
    },
    "description": {
      "type": "string",

      "description": "What shipped, in one or two sentences."
    },

  },

    arguments 30 lines
  • add_brand unknown never probed

    Start measuring a brand: does ChatGPT, Perplexity, Claude or Google AI mention it, and who does AI recommend instead? Give the brand's website (or its app store, Google Maps, YouTube or Instagram link). Proofsource reads the site, picks the buyer questions, and starts the first scan across the AI engines. Reading the site takes 1-2 minutes; if it is still running, call again with the same link and it picks up the same run, never a second one. Returns the brand_id; then use get_scan_status.

    mcp-tool

    {
  "type": "object",
  "required": [
    "link"
  ],
  "properties": {
    "link": {
      "type": "string",
      "maxLength": 2048,
      "description": "The brand's website, like acme.com, or its app store, Google Maps, YouTube or Instagram link."
    },
    "description": {
      "type": "string",
      "maxLength": 1000,
      "description": "Optional: what the brand sells, in a sentence. Only needed when add_brand says it couldn't read the website."
    }
  },
  "additionalProperties": false
}
    arguments 19 lines
  • get_scan_status unknown never probed

    Progress of a brand's first scan after add_brand: the stage, how many AI answers are in out of how many expected, per engine, and when it should finish. Once complete, use get_visibility for the results.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "brand_id": {
      "type": "string",
      "description": "Brand id from list_brands or add_brand. May be omitted when the workspace tracks a single brand."
    }
  },
  "additionalProperties": false
}
    arguments 10 lines
  • get_report_link unknown never probed

    A link to the brand's AI visibility report to share with a team or client: how often AI answers mention the brand, which competitors they name instead, and which sources they cite. Returns the newest finished report's own unlisted link. Reports are built automatically after a brand's first scan.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "brand_id": {

    arguments 10 lines
  • see_example unknown never probed

    Shows what Proofsource measures, without signing in: a real visibility card for one example brand (Tesla), from answers Proofsource collected from ChatGPT, Perplexity, Claude and Google AI Overviews. It shows how often AI answers mention the brand, per engine, which competitors they name instead, and sample answers. Use it when someone asks whether their brand shows up in AI answers and has not signed in. It always shows the example brand; to check their own brand they sign in.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "brand": {
      "type": "string",
      "maxLength": 200,
      "description": "Optional: the brand the person asked about. The example card is shown either way, with a note to sign in to check that brand."
    }

_ 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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 9c05f53335d236f3.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/9c05f53335d236f3/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ 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.
