Hosted onboarding API MCP Server Integration Guide
Section A: Quick Answer & Architectural Summary
The Hosted onboarding API Model Context Protocol (MCP) integration bridges AI coding assistants to the Hosted onboarding API security API. It exposes 2 validated endpoint operations as callable tools for Claude Desktop, Cursor, and VS Code. Configuration is managed via hosted registry at /config/adyen-com-hopservice.json or local stdio bridge execution. Operates with zero authentication credentials out of the box. Contains 2 mutating operations (POST/PUT/DELETE); user confirmation is recommended before triggering write operations.

Technical Overview & Protocol Integration
The Hosted Onboarding API, provided by Adyen for marketplace and platform solutions, is a specialized service designed to streamline the complex process of verifying and onboarding sub-merchants or sellers. It serves as a classic integration pathway, offering programmatic generation of unique, secure URLs that redirect end-users—typically business clients—to Adyen's managed onboarding portal. This offloads the significant compliance and user-experience burden from the platform operator. Core capabilities include the instantiation of dedicated onboarding sessions (POST /getOnboardingUrl) and the provision of PCI DSS compliance questionnaire links (POST /getPciQuestionnaireUrl). Typical use cases span digital marketplaces requiring Know Your Customer (KYC) checks, crowdfunding platforms onboarding project owners, and payment facilitators managing a portfolio of smaller merchants who need to submit verification documents and business details in a structured, Adyen-hosted environment.
When exposed as a tool via the Model Context Protocol (MCP) to an AI coding assistant, this API unlocks significant value by enabling the AI to act as a dynamic facilitator within the developer's workflow. Instead of manually consulting documentation and writing boilerplate code to fetch URLs, the developer can instruct the AI to directly interact with the onboarding process. The AI can generate ready-to-use, context-aware onboarding links for specific test users or merchants in a staging environment, effectively simulating the user journey. It can also retrieve PCI questionnaire links to test compliance flows without leaving the integrated development environment. This transforms the AI from a passive code generator into an active participant in testing and validating the onboarding lifecycle, accelerating development cycles and reducing context-switching.
Practically, a developer could instruct the AI agent to perform a series of dynamic tasks that integrate seamlessly into their coding session. For example, "Generate a fresh onboarding URL for the test merchant with account holder type 'business' and include my custom query parameters for tracking." The AI would execute the appropriate API call and return the URL for immediate use in a frontend test. Another task could be: "Check if the onboarding status for sub-merchant ID 'X' shows that the PCI questionnaire has been issued, and if not, generate the URL." This allows the AI to probe system state (if additional lookup endpoints were available) and perform conditional actions. Furthermore, the AI could be tasked with scripting a sequence: "First, create an onboarding URL, then parse the response to extract the link and embed it into a test HTML file for a user story," automating a multi-step developer chore.
Critical to the secure deployment of an MCP server for this API is acknowledging that while the specific endpoints listed (getOnboardingUrl, getPciQuestionnaireUrl) might not require individual endpoint authentication, they are invoked within a secure session context that relies on an authenticated merchant account. Developers must ensure the MCP server configuration securely manages the necessary authentication credentials (such as API keys) in its backend environment, never exposing them to the AI client or user. The principle of least privilege is paramount; the API key used should have permissions scoped exclusively to the onboarding endpoints, restricting any potential lateral movement. All communication between the AI tool and the MCP server must occur over a secure channel, and the server itself should implement rigorous input validation to prevent injection attacks, ensuring that parameters passed by the AI are strictly sanitized before being forwarded to Adyen's production services.
By translating the OpenAPI 3.0 specification for Hosted onboarding API into native Model Context Protocol (MCP) tool definitions, developers and AI agents gain programmatic access to endpoints over stdio or HTTP transports. Every endpoint is translated into a discrete tool payload complete with input argument validation, parameter descriptions, and return type definitions.

Security Considerations & Sandbox Guidance: Hosted onboarding API

Read & Mutating Operations
Local MCP bridge process making outbound HTTPS requests to upstream API
Isolation & Principle of Least Privilege
Ensure outbound network access to the API endpoint is permitted. Use restricted API tokens with minimal read/write scopes.
Actionable Operational Guidelines
- Verify network firewall rules allow outbound traffic to upstream API endpoints.
- Review arguments for mutating endpoints (/getOnboardingUrl, /getPciQuestionnaireUrl) before execution.
- Apply token rate limits and monitor usage in your provider dashboard to prevent unexpected quota consumption.
