How this service works
Gelieferte Ressourcenverweise gegen freigegebene Schemes, Origins und Pfadgrenzen aufloesen.
Output
Returns a structured grant resolution indicating for each supplied resource link whether it falls within the declared allowed schemes, permitted origins, and path boundaries, effectively partitioning links into authorized and unauthorized sets.
Example use cases
Widget iframe resource link audit
“I have a list of resource URLs my embedded widget is trying to load — can you check them against our allowed schemes (https only) and permitted origins (widgets.myapp.com under /embed/) and tell me which ones pass and which are blocked?”
CSP-style link grant enforcement for agent output
“My agent is generating links to external resources, and I need to make sure they all fall within our allowed targets: origins limited to cdn.brand.com and api.brand.com, schemes limited to https, paths must start with /public/. Can you resolve which links are within grant and which violate the policy?”
Third-party integration URL compliance check
“Before we forward these webhook callback URLs from our third-party integrations to the browser, validate them against our allowed schemes (https, http) and permitted origins (*.partner.io under /hooks/) — flag anything outside those boundaries.”
Technical details
Endpoint
POSThttps://detect.halowerk.com/v1/integration/mcp-resource-link-target-grants?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enforce structured allow-list policies on resource URLs — specifically when you have explicit scheme, origin, and path constraints to check against. Prefer this over generic URL validation when your policy is multi-dimensional (scheme + origin + path) and you need a machine-readable grant/deny decision per link.
Side effects
- Missing required artifact fields (resource_links, allowed_schemes, or allowed_targets) returns validation error
- Malformed URL in resource_links may result in parse failure or rejection
- Empty allowed_targets or allowed_schemes results in all links being denied
- Ambiguous or overlapping path boundary declarations may produce unexpected grant results
- Payment not attached or insufficient USDC balance returns 402 Payment Required
