Microsoft Build MCP Server

An MCP (Model Context Protocol) server that exposes Microsoft Build 2025 conference session data through 3 simple tools. AI assistants can search sessions, get details, and browse the schedule — all via natural language.

Built with ASP.NET Core, the official MCP C# SDK, and Retrievo for BM25 full-text search.

Tools

Example Queries

search_sessions(query: "AI agents")
search_sessions(query: "Scott Hanselman")
search_sessions(query: "Kubernetes Python", date: "2025-05-20")
get_session(sessionCode: "BRK199")
get_schedule(date: "2025-05-20")
get_schedule(date: "2025-05-21", topic: "AI")

Quick Start

cd BuildMcpServer
dotnet run

The MCP endpoint will be at http://localhost:3001/mcp (stateless HTTP transport).

Health Check

GET http://localhost:3001/health

Connect to an MCP Client

GitHub Copilot CLI

copilot mcp add build-sessions --transport http --url http://localhost:3001/mcp

VS Code (mcp.json)

{
  "servers": {
    "build-sessions": {
      "type": "http",
      "url": "http://localhost:3001/mcp"
    }
  }
}

Docker

cd BuildMcpServer
docker build -t build-mcp-server .
docker run -p 8080:8080 build-mcp-server

Tech Stack

Data Source

Session data is sourced from the public Microsoft Build 2025 event API:

https://eventtools.event.microsoft.com/build2025-prod/fallback/session-all-en-us.json

The file BuildMcpServer/Data/session-all-en-us.json is a snapshot of this endpoint (520 sessions).

Reference Materials

The AspNetCoreMcpServer/ folder contains the reference sample code for building an HTTP remote MCP server with the official C# SDK. mcp_tool_draft.txt is the original PM tool specification (16 tools) that was simplified down to 3 for this PoC.

CLI Tool

A standalone CLI is also available in the cli/ folder. See cli/README.md for details.

cd cli && npm install
node bin/build-sessions.js search "AI agents"
node bin/build-sessions.js get BRK199
node bin
