Disclose MCP Server

An MCP server for querying merchant disclosure signals published via Disclose.

What it does

Merchants publish operational signals — return rates, fulfillment accuracy, chargeback ratios — along with permitted use terms. This MCP server lets any AI agent query that data directly.

The server checks four discovery paths in order:

/.well-known/disclose — canonical path
/.well-known/disclose.json — canonical path with explicit extension
/disclose.json — fallback for hosted platforms like Shopify that do not support the /.well-known/ directory
JSON-LD block in page <head> — for merchants using script-tag injection

Signals sourced from the Shopify API and computed by Sure Signal are returned with full provenance metadata: source, reported_by, computed_by, attestation_level, and attestation. Attestation is null until a third-party Signatory (such as Loop Returns) cryptographically signs the signal.

Available Tools

get_merchant_disclosure(domain)

Fetches a merchant's published disclosure signals from their domain. Returns all signals the merchant has chosen to publish, with provenance metadata, or an error if no disclosure is found.

Example: get_merchant_disclosure("example.com")

check_signal_coverage(domain)

Returns a structured coverage report for the seven Sure Signal V1 signals: which are present, which are missing, whether any carry attestation, and an overall coverage percentage. Useful for agents evaluating merchant data completeness before a purchase decision.
