AI travel assistants are getting better at planning trips, but useful beach recommendations still depend on the quality and freshness of the underlying data. A conversational interface can suggest a destination, yet it needs structured beach information to answer the questions travelers actually ask: Which beaches are nearby? Is the weather suitable? What is the water-quality grade? Which options meet a conservative definition of swimmable?
Beach Day API now supports the Model Context Protocol (MCP), giving developers a practical way to bring beach data into AI assistants, agent workflows, destination apps, and prototypes. Beach Day MCP is available at https://beachdayapi.com/mcp over Streamable HTTP. It is embedded in the existing Beach Day API service, so you use the same account, API key, and credit system rather than creating a separate MCP service.
What Beach Day MCP makes possible
MCP provides a standard way for compatible AI clients to discover and call tools. In this case, the tools are read-only Beach Day API operations. An assistant can use them to turn a natural-language request into a sequence of structured lookups, then present the results in a format that makes sense for the user.
That is useful when an application needs more than a static list of beaches. A travel assistant could find beaches in a destination, check weather, compare water quality, and narrow the list to places that satisfy a clearly stated swim-readiness rule. A vacation-planning product could use the same tools behind a conversational search box. A developer building an agent prototype can connect real beach data without writing a custom adapter for every individual tool.
Six read-only MCP travel tools
Beach Day MCP currently exposes six focused tools:
list_countries: discover available country options. Cost: 1 credit.search_beaches: find beaches matching a search request. Cost: 1 credit.get_beach: retrieve details for a specific beach. Cost: 5 credits.get_weather: retrieve weather information for a beach. Cost: 3 credits.get_water_quality: retrieve water-quality information. Cost: 3 credits.find_swimmable_beaches: find beaches meeting the conservative swim-readiness criteria. Cost: 10 credits.
The tools are intentionally read-only. MCP does not write beach records, change account data, or replace the REST API. It provides a convenient tool interface for compatible clients while the existing API remains available for applications that need direct HTTP integration, predictable request handling, or their own orchestration layer.
How to connect an AI client
Use an MCP-compatible client that supports remote Streamable HTTP servers. Add Beach Day MCP as a remote server with this endpoint:
https://beachdayapi.com/mcpAuthenticate each request with an existing Beach Day API key in the HTTP Authorization header:
Authorization: Bearer YOUR_API_KEYYOUR_API_KEY is a placeholder, not a key to copy literally. Create or retrieve your key through your Beach Day API account, then keep it in the client’s secure environment or secret manager. Never paste a real key into a public prompt, source repository, screenshot, or article.
The exact configuration shape varies by MCP client, but the important values do not: the remote endpoint is https://beachdayapi.com/mcp, the transport is Streamable HTTP, and the request must include your Bearer token. Start with a low-cost discovery call such as list_countries or search_beaches, then make more expensive detail or filtering calls only when the user’s request requires them.
Understanding the credit model
Beach Day MCP uses the existing Beach Day API key and credit system. Each tool call consumes credits according to the operation above. This matters for agent design because an assistant may make several calls to answer one question. A good workflow can search first, retrieve only the necessary details, and explain when a request involves a higher-cost operation.
For example, a destination assistant might spend 1 credit discovering countries, 1 credit searching beaches, and 3 credits checking weather for a selected result. If the user asks specifically for conservative swim-ready options, find_swimmable_beaches costs 10 credits. The tool uses two explicit criteria: a Beach Day score of at least 7.0 and a water-quality grade of A or B. Calling out that rule helps the user understand what the result means. It is a conservative filter, not a guarantee of safety or a substitute for current local guidance.
Review the Beach Day API documentation for current usage details and the credit pricing page before putting an agent into production. Add application-level budgets, caching where appropriate, and confirmation steps for workflows that could trigger many tool calls.
Practical use cases for Beach Day MCP
AI travel assistants
An assistant can answer questions such as “I have one afternoon near this destination. Which beaches should I consider?” It can search, compare relevant conditions, and explain the data behind a shortlist instead of inventing a recommendation from general knowledge.
Conversational beach search
Destination apps can let users ask for beaches in ordinary language. MCP handles the tool connection while the application controls the user experience, permissions, presentation, and any business rules layered on top.
Trip planning and itinerary products
An itinerary builder can check beach details and weather while assembling a day plan. Because the tools are read-only, the surrounding application remains responsible for saving itineraries, bookings, or user preferences.
Agent workflows and prototypes
Developers can connect compatible agents to real beach data during experimentation, then decide whether to keep the MCP integration or call the REST API directly for a more specialized production architecture. MCP is a useful way to validate the interaction before investing in a custom tool layer.
Security and privacy guidance
Treat your Beach Day API key as a secret. Store it in environment variables or a managed secret store, restrict access to the services that need it, and avoid logging Authorization headers or full request payloads that contain credentials. If an agent platform stores conversation transcripts, review its retention and access settings before sending sensitive user information through it.
Keep the tool scope clear for users and operators. Beach Day MCP is read-only and supplies beach information through the existing service. It should not be presented as an agent that can modify data or take booking, payment, messaging, or safety-enforcement actions. If your product adds those capabilities, implement and disclose them separately.
Designing a useful agent interaction
The best MCP experience keeps the assistant’s reasoning grounded in tool results. Ask it to identify the destination before requesting detailed conditions, show which beach records informed the answer, and distinguish missing information from a negative condition. Your application can also define a small response contract: name the beach, show the relevant score or grade when returned, include the weather context, and link users to the underlying product experience for deeper detail.
This approach helps prevent a common failure mode in conversational search: a fluent answer that sounds specific but is not supported by a current lookup. MCP supplies the connection to the tools, while your prompt, UI, and application logic should determine when a tool is required and how its result is communicated.
Start building
Beach Day MCP gives developers a direct path from a compatible AI client to structured beach data: one Streamable HTTP endpoint, six read-only tools, and the same API-key and credit model used by the existing service. That combination makes it suitable for AI travel assistants, destination discovery, agent experiments, and conversational product features.
To get started, read the API documentation, create an account and get a Beach Day API key, then connect https://beachdayapi.com/mcp in an MCP-compatible client. Begin with a small, observable workflow, budget its credits, and make the data source visible in the experience. When you are ready to build beyond a prototype, the same Beach Day API account can support a direct REST integration as well.
