MCP Server (AI Integration)

adrs includes an MCP (Model Context Protocol) server for AI agent integration (enabled by default).

Add to Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "adrs": {
      "command": "adrs",
      "args": ["mcp", "serve"],
      "cwd": "/path/to/your/project"
    }
  }
}

The MCP server provides 15 tools for reading, creating, and managing ADRs.

Library

adrs is built on the adrs-core library, which can be used independently:

[dependencies]
adrs-core = "0.7"

use adrs_core::Repository;

let repo = Repository::open(".")?;
for adr in repo.list()? {
    println!("{}: {}", adr.number, adr.title);
}

See library documentation for more details.
