Blockquote bronze

blockquote.io

“Blockquote scores a public URL 0-100 for how likely ChatGPT, Perplexity and Google AI Overviews are to cite it, and returns the fixes. The skills below are served over the Model Context Protocol (Streamable HTTP) at https://mcp.blockquote.io/mcp. Blockquote runs no A2A JSON-RPC endpoint, so the interface below declares the MCP binding it does serve, not an A2A one.

Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Google Trust Services domain-validated
Valid until 15 Jan 2027 as of our check on 13 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

Names on this certificate (3)

blockquote.io, bridge.blockquote.io, *.bridge.blockquote.io.
Connection: TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 13 Nov 2026. What this means
DANE / TLSA: Not verified
Discovery: Well-known document
This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 20 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
AI-facing documents: Publishes /llms.txt — “Blockquote” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (1 key, Ed25519) — the operator publishes keys so their agent's signed requests can be verified. agenttru.st recorded that the directory exists; it has not verified a signature.

Fetched from this host during verification. Neither document is how this agent was discovered.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of blockquote.io controls every word below.

Preview selected website pages

Preview up to ten normalized, unique pages of one website and their maximum scan quota use. Supply URLs or a sitemap URL. Requires an account key. No scans start.

auditwebsiteaccount

Start a selected-page audit

Start an account-private audit of up to ten selected pages from one website. Uses existing per-page scan quotas. Supply a stable requestKey for retries; poll get_audit and resume queued pages. Reads pages without changing them.

auditwebsiteaccount

Read grouped audit findings

Read this account's per-page audit progress, partial failures, grouped check evidence and prioritized fixes. Plan gates apply. Repeated findings suggest a possible common cause, not a proven template error. No website-wide score or citation claim.

auditwebsiteaccount

Resume queued audit pages

Start only queued pages of this account's audit within the remaining quota and concurrency limit. Running and completed pages keep their scan IDs. Uncertain dispatches are not repeated automatically.

auditwebsiteaccount

Repeat selected audit pages

Create a follow-up audit for selected URLs from this account's original audit. Supply a stable requestKey for retries. Uses scan quota and compares the same pages as resolved, unchanged, new or not comparable; method changes prevent improvement claims.

auditwebsiteaccount

Start an AI-citability scan

Scan a public HTTPS URL for AI citability. Returns a scan id at once; poll get_scan until the status is done.

seocitabilityauditscan

Examples it gives

Scan example.com/blog/post for AI citability.

Get scan status and report

Read a scan by id as a summary, as the complete report JSON, or as one Markdown document.

reportscan

Examples it gives

Give me the full markdown report for scan s4t8n2vq6w1e.

List all citability checks

The catalog of every check a scan runs, with what it measures and why it matters.

catalogchecks

Examples it gives

Which citability checks does Blockquote run?

Explain one check in depth

What one check measures, why it matters for AI citation, and the typical fix.

catalogchecksfix

Examples it gives

Explain the schema-faqpage check.

Account plan and usage

Plan, limits and scans used today and this month for the API key in the Authorization header.

accountusage

Examples it gives

How many scans do I have left this month?

Compare two scans of one URL

What changed between two finished scans of one page: score deltas, flipped checks, and resolved, new and open recommendations.

reportdiffhistory

Examples it gives

Compare the two newest scans of example.com/pricing.

List monitored URLs

The URLs this account re-scans weekly, each with its last score and run time.

monitoraccount

Examples it gives

Which pages am I monitoring?

Add a URL to the weekly monitor

Add a public HTTPS URL to this account's weekly re-scan. Monitoring needs a paid plan.

monitoraccount

Examples it gives

Monitor example.com/pricing every week.

Stop monitoring a URL

Remove one monitor by its id. Weekly re-scans of that URL stop; the reports it produced stay readable.

monitoraccount

Examples it gives

Stop monitoring monitor m7k2p9qx41ba.

Audit agent readiness

Audit how well AI agents can find, read and use a domain, an MCP server or an MCP App. Returns a score, evidence per check and a fix for each failure.

agentsmcpauditreadiness

Examples it gives

Audit example.com for agent readiness.
Audit the MCP server at https://mcp.example.com/mcp.

Get an agent-readiness report

Read a stored agent-readiness report as a summary, JSON or one Markdown document.

agentsreport

Examples it gives

Show the agent-readiness report as Markdown.

What its catalog declares
