Model Context Protocol (MCP)

Connect to remote MCP servers as a client and expose your application's tools, prompts, and resources as an MCP server.

The Model Context Protocol standardizes how AI applications discover and invoke tools, prompts, and resources across process boundaries. The framework provides both sides of the protocol.

Client — Consume Remote MCP Servers​

Connect to external MCP servers, discover their tools, and make them available in the AI orchestrator.

builder.Services
    .AddCoreAIServices()
    .AddCoreAIOrchestration()
    .AddCoreAIMcpClient();

Key capabilities:

  • SSE transport — Connect to remote MCP servers over HTTP with full authentication support (API key, Basic, OAuth2, custom headers)
  • StdIO transport — Communicate with locally installed MCP server processes via stdin/stdout
  • Automatic tool discovery — Discovered tools appear in the orchestrator's tool registry and are invoked transparently
  • Capability resolution — Semantic similarity filtering to select relevant tools from large MCP server catalogs

Server — Expose Your AI Capabilities​

Expose your registered AI tools, prompts, and resources to external MCP clients.

builder.Services
    .AddCoreAIServices()
    .AddCoreAIOrchestration()
    .AddCoreAIMcpServer();

Key capabilities:

  • Tool exposure — Registered AI tools become callable by external MCP clients
  • Prompt serving — Prompts from the catalog and code-registered instances are listed and retrievable
  • Resource serving — Files and data served through pluggable resource type handlers (FTP, SFTP, custom)
  • Authentication — OpenID Connect, API key, or no-auth for development

Resource Type Handlers​

Create custom resource type handlers to serve files, data, or content from any protocol as MCP resources.

builder.Services
    .AddCoreAIMcpServer()
    .AddMcpResourceType<MyDatabaseResourceHandler>("database");
