MCP Service Broker

A Spring Cloud Open Service Broker for registering and binding Model Context Protocol (MCP) servers. Supports Cloud Foundry, local, and Kubernetes profiles.

Features

• Register MCP servers via Cloud Foundry Service Broker API or REST API
• Bind MCP servers to apps (credentials provided at bind time)
• REST API for graphical management
• React UI for catalog and registration (see frontend/)
• Profile-based persistence: in-memory (local/k8s), Postgres (Cloud Foundry)
• Actuator endpoints for health/info

Quick Start

Local Development

./mvnw spring-boot:run -Dspring-boot.run.profiles=local

Cloud Foundry

Bind a Postgres service and push with cloudfoundry profile. Datasource auto-configured from VCAP_SERVICES.

REST API

• GET /api/mcp-servers - List all MCP servers
• POST /api/mcp-servers - Register new MCP server (JSON body)
• DELETE /api/mcp-servers/{instanceId} - Delete MCP server

UI

• Start the React UI in frontend/ (see frontend README)

Profiles

• local: In-memory repo
• cloudfoundry: Postgres via JPA (VCAP_SERVICES)
• kubernetes: In-memory repo

Spring Boot Actuator Endpoints

The following actuator endpoints are enabled by default:

• /actuator/health — Returns application health status (useful for Cloud Foundry, Kubernetes, and monitoring tools).
• /actuator/info — Returns application info (can be customized in application properties).

You can access these endpoints at:

• Local: http://localhost:8081/actuator/health and http://localhost:8081/actuator/info
• Cloud Foundry: https://
• Kubernetes: http://

To expose more actuator endpoints, update management.endpoints.web.exposure.include in your properties files.
