MCP server

As explained in Building Distributed Applications that Work

An MCP server is a software component that exposes tools, resources, or contextual information to a language model through the Model Context Protocol.

An MCP server exposes tools, resources, and contextual information through a standard interface. In a coding environment, the agent is the client: it discovers available tools, calls one with structured inputs, and receives the result to guide its next action. section 10.4.3

With Aspire, configure the server from the folder containing the host project for a coding assistant such as Claude Code, Codex, or Copilot CLI. The assistant can then access tools for inspecting and working with the current Aspire instance. section 10.4.1

Aspire’s available tools support tasks such as:

• Listing hosted services and executing commands supported by a resource. section 10.4.1
• Inspecting console logs, structured logs, and traces for diagnostics. section 10.4.1
• Finding integration packages and their documentation, or selecting the relevant app host. section 10.4.1

aspire mcp init

Use the Aspire MCP initialization command when setting up the server from the host-project folder. section 10.4.1

How Building Distributed Applications that Work covers it

How deep it goes

Defines the client-server interaction and lists Aspire tools, while treating the available tool list as non-exhaustive.

Examples

Uses service discovery, resource commands, logs, traces, integration documentation, and app-host selection as tool examples.

What you can do after

Configure an Aspire MCP server for a coding assistant and use its tools to inspect and work with the Aspire instance.

How it connects

Links MCP servers with AI agents, Aspire resources, integration packages, logs, and traces.
