MCP Tools ​

The All Aboard MCP server exposes the following tools to the model. The model decides which tools to call based on the task at hand.

list_documentation ​

Lists all available documentation sections and pages with short descriptions. Use this first to discover what is available before fetching specific content.

Parameters: None

Example output:

## Getting Started
- Introduction: Overview of All Aboard products and quick start guide
- Getting Started: Prerequisites, API endpoints, authentication setup
...

read_documentation ​

Fetches one or more documentation pages by slug and returns their content as clean plain-text markdown. Always call list_documentation first to find relevant slugs, then fetch only the pages you need.

A slug is the URL path without the leading slash:

Pass multiple slugs to fetch several pages in a single call.

Parameters:

explore_schema ​

Browses the live GraphQL schema. Returns operation signatures with argument types and return types, or a list of available types.

Parameters:

Example — list all queries containing "journey":

explore_schema({ category: "queries", filter: "journey" })

explore_schema({ category: "queries", filter: "journey" })

Example output:

- **getJourneys**(origin: String!, destination: String!, date: String!, filter: JourneyFilterInput): [Journey!]!
  Find available train routes between two locations on a specific date.
- **getJourneyOffer**(journey: ID!, passengers: [PassengerInput!]!): JourneyOffer
  Get pricing and offers for a journey.

- **getJourneys**(origin: String!, destination: String!, date: String!, filter: JourneyFilterInput): [Journey!]!
  Find available train routes between two locations on a specific date.
- **getJourneyOffer**(journey: ID!, passengers: [PassengerInput!]!): JourneyOffer
  Get pricing and offers for a journey.

get_type ​

Returns full details of a specific GraphQL type: all fields with their argument types and return types, enum values, input fields, interfaces implemented, and possible types for unions/interfaces.

Parameters:

Example:

get_type({ name: "Booking" })

get_type({ name: "Booking" })

If the type is not found, the tool returns suggestions for similarly named types.

execute_query ​

Executes a GraphQL query or mutation against the All Aboard API and returns the JSON response.

Each call requires the user's own API key passed as the apiKey parameter. The MCP server does not store or inject credentials — the key is sent directly to the API on the user's behalf and is not retained between calls. If the user has not provided their API key, ask for it before calling this tool.

API keys are available from the All Aboard Dashboard.

Parameters:

Example:

query FindJourneys {
  getJourneys(
    origin: "Sb0ISveC"
    destination: "p6fERure"
    date: "2025-06-15"
  ) {
    id
    itinerary {
      duration
    }
  }
}

query FindJourneys {
  getJourneys(
    origin: "Sb0ISveC"
    destination: "p6fERure"
    date: "2025-06-15"
  ) {
    id
    itinerary {
      duration
    }
  }
}

GraphQL errors in the response are surfaced clearly alongside the full response body for debugging.
