AI agents call search_providers to retrieve information from GPH Intelligence — Healthcare Service Provider Finder (API key required) without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though search_providers only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Paginated browse of the healthcare service provider directory filtered by category, location, and minimum quality score. Returns a page of providers with {company_name, category, city, state_abbr, quality_score (0-100), verified status, contact info, slug}.
