Blue Pillow Hotels & Stays
https://mcp.b2a.bluepillow.com/mcp ↗
Description
Neutral hotel & stay price comparison for AI agents: live prices from 16+ booking operators. No signup. Blue Pillow consolidates live availability, per-operator pricing, ratings and booking links across millions of properties — hotels, B&Bs, apartments, vacation rentals, farmstays, hostels, villas and resorts. One query returns the multi-source price comparison an agent would otherwise have to assemble by visiting each booking site, with date-specific quotes, per-operator scarcity signals and free-cancellation flags. **No signup, no OAuth, no card.** The `b2a_get_key` tool issues a free anonymous key in-band; it is permanent and reusable across sessions. **Tools** - `b2a_get_key` — issue a free anonymous API key - `resolve_destination` — turn a place name into a destination id - `discover_destinations_near` — fan out sub-destinations from coordinates, for region-level intents - `search_stays` — ranked search across operators for a location and stay parameters - `get_property_details

Agent readability score
Strengths
- Clear purpose for 'search_stays' and 'b2a_get_key' tools.
- Provides live availability and multi-source price comparison capabilities.
Weaknesses
- Tool names like 'get_property_details' and 'check_property_availability' are functionally overlapping.

- No clear error handling or constraint documentation in tool descriptions.
search_stays— Description cuts off mid-sentence, missing critical details about ranking logic.get_property_details— Ambiguous 'headline rating' definition; unclear if it includes breakdowns.resolve_destination— Unclear if coordinates are required or optional in input parameters.b2a_get_key— No input parameters defined despite being a key-issuing tool.
