Valet Parking Directory Tools (7)
valet_list_services
List the 9 canonical valet service slugs with display name and category. Use this when an agent needs to validate or discover the supported service taxonomy before composing a follow-up search. Returns the in-bundle catalog; no upstream call; no isError path.
valet_get_operator
Get the full operator profile by slug including address, phone, website, services, venues_served, FAQs, and tipping note. Use this when an agent has a slug from a search tool or directory URL and needs the complete profile to rank or present. Returns isError on slug 404 or upstream outage.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Volta MCP Server is categorized under Security and uses a local stdio subprocess. In contrast, Valet Parking Directory belongs to Security using remote streaming HTTP/SSE transport. Select Volta MCP Server when you need capabilities focused on security and Valet Parking Directory when you require tools for security.
Search the cities directory by name prefix with population-ranked results. Use this when an agent needs to resolve a partial city name into a canonical city slug plus state slug plus lat/lng before composing valet_find_operators_in_city or valet_find_operators_near. Empty array if no matches.
valet_find_operators_in_city
List valet operators serving a city slug plus state slug, optionally narrowed by service. Use this when an agent has a city already disambiguated and wants its operator roster ranked premium tier first then name. Empty array if no listed operators.
valet_search_by_service_and_city
Search valet operators by service slug plus city slug across all matching states. Use this when an agent has both a service slug and a city slug and wants a cross-state tier-then-name ranked list. Invalid service slugs surface the 9 canonical alternatives.
valet_find_nearest_operators
List nearest valet operators within a 100-mile cap of a coordinate, optionally narrowed by service. Use this when a user is in a city with no listed operators and you need the closest available fallback ranked nearest-first. Empty array if nothing within 100 miles.
valet_find_operators_near
Find valet operators within a given radius of a coordinate, ranked premium tier first then distance. Use this when you have a coordinate and an event-context radius (5mi single venue, 25mi metro, 50mi regional). radius_miles is required; empty array if no matches.
