OctoTrip Rental Cars

# OctoTrip Rental Cars MCP Server Free, no-login MCP server for discovering and comparing rental cars with real-time pricing from multiple providers worldwide. **Endpoint:** `https://mcp.octotrip.app/rental-cars/mcp` ## Affiliate Disclosure OctoTrip is free to use. Booking links contain affiliate attribution -- OctoTrip may earn a commission at no extra cost to you. Search results are ranked by price within each car category, not by affiliate payout. ## Quick Start Add to your MCP client configuration: ```json { "mcpServers": { "octotrip-rental-cars": { "url": "https://mcp.octotrip.app/rental-cars/mcp" } } } ``` No API key or login required. ## Tool: `search` Search for rental cars by location, dates, and preferences. Returns available cars from multiple vendors grouped by category (economy, compact, SUV, etc.), showing the cheapest options in each. Dates can be in any common format (YYYY-MM-DD, DD.MM.YYYY, "August 1, 2026", etc.). ### Parameters | Parameter | Type | Required | Default | Description | |---|---|---|---|---| | `location` | string | yes | -- | Pickup city, airport, or address | | `pickup_date` | string | yes | -- | Any common date format | | `dropoff_date` | string | yes | -- | Any common date format | | `dropoff_location` | string | no | same as pickup | For one-way rentals | | `pickup_time` | string | no | `"12:00"` | HH:MM format | | `dropoff_time` | string | no | `"12:00"` | HH:MM format | | `currency` | string | no | `"EUR"` | ISO 4217 currency code | | `language` | string | no | `"en"` | 2-letter language code | | `age` | integer | no | `30` | Driver age (younger drivers may incur surcharges) | ### Response Format Results are grouped by SIPP car category with the cheapest 2 options per group: ```json { "results": [ { "name": "Volkswagen Golf", "vendor": "Europcar", "sipp": "CDMR", "category": "Compact", "price": 181.03, "price_per_day": 45.26, "pay_now": 181.03, "pay_later": 0, "currency": "EUR", "transmission": "manual", "passengers": 5, "bags": 1, "doors": 4, "air_con": true, "fuel_policy": "Full to Full", "mileage": "Unlimited", "free_cancellation": true, "free_amendment": true, "deposit": 800, "excess": 950, "included_protections": ["Collision Damage Waiver", "Theft Protection"], "image_url": "https://...", "booking_url": "https://...", "link_type": "affiliate", "affiliate_disclosure": "This link contains affiliate attribution. OctoTrip may earn a commission at no extra cost to you." } ], "total": 23, "total_available": 379, "rental_days": 4, "pickup_location_resolved": "Munich International Airport", "dropoff_location_resolved": "Munich International Airport", "query": { ... } } ``` ### Error Responses The server returns structured errors with suggestions: - **`location_not_found`** -- location could not be resolved. Try a more specific name or airport. - **`invalid_date`** -- date format not recognized. Use YYYY-MM-DD, DD.MM.YYYY, or similar. - **`no_results`** -- no cars available for the given criteria. Try different dates or a nearby location. ## Example Prompts - Find me a cheap rental car at Amsterdam Schiphol for next weekend - Compare automatic SUVs available in Munich Airport for July 10-15 - I need a car in Barcelona from August 1-14, budget around 30 EUR/day - One-way rental from Berlin to Hamburg, picking up Friday, returning Monday - What's the cheapest economy car at London Heathrow for a week in September? ## Privacy This server does not store, log, or track any user data. Queries are forwarded to provider APIs and results are returned directly. See [PRIVACY.md](PRIVACY.md) for details. ## Security To report a vulnerability, see [SECURITY.md](SECURITY.md). ## License MIT

MCP TrustOps

TrustOps turns this report into operational controls: freshness SLAs, authenticated validation, semantic benchmarks, policy exports, alert subscriptions, badges, cost/compliance metadata, and runtime routing. Fresh trusted index decisions stay separate from long-tail inventory so stale scores do not masquerade as current evidence.
