Prowl tools (9)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • prowl_alternatives

    Find alternative services in the same category as a given service. Useful for fallback options.

  • prowl_audit

    Get a full ASO audit report: score breakdown, issues, benchmark readiness, latency, uptime, and action plan.

  • prowl_batch_metrics

    Get basic metrics for multiple services in one call (up to 20). More efficient than individual lookups.

  • prowl_compare

    Compare 2-5 services side by side. Returns scores, latency, uptime, and a recommendation.

  • prowl_discover

    Search the Prowl service directory by keyword, category, or filters. Returns ranked SaaS APIs with scores.

  • prowl_feedback

    Report success or failure after using a service. This improves scores for all agents.

  • prowl_get_service

    Look up a specific service by its URL-friendly slug (e.g. 'stripe', 'openai').

  • prowl_metrics

    Get ASO score and verification status for a service. Use this to evaluate if a service is reliable.

  • prowl_search

    Natural language search for services. Use when the user describes what they need rather than naming a specific API.
