## Quick Connect (Zero-Install Remote MCP)

Add the hosted Streamable HTTP endpoint directly to your `.mcp.json`, Cursor, Claude Code, or Claude Desktop config with zero local dependencies:

```json
{
  "mcpServers": {
    "agentbreakwatch": {
      "url": "https://agentbreakwatch.com/api/mcp"
    }
  }
}
```

Or run locally via `npx` (stdio transport):

```json
{
  "mcpServers": {
    "agentbreakwatch": {
      "command": "npx",
      "args": ["-y", "agentbreakwatch-mcp"]
    }
  }
}
```

## Available MCP Tools

1. **`check_stack_drift`**: Pass the raw contents of a `.mcp.json`, `package.json`, or `requirements.txt` file to detect breaking major version jumps, unpinned `@latest` MCP servers, and archived packages, with exact version pin commands.
2. **`get_package_stability`**: Retrieve live npm/PyPI version, publish date, 90-day release velocity, 0-100 stability score, `tools/list` schema drift risk, and copy-paste before/after migration code for any of the 256 tracked packages.
3. **`list_volatile_packages`**: Query the fastest-changing Agent SDKs and MCP servers over the last 90 days, optionally filtered by `kind` (`sdk` or `mcp`) or ecosystem category.
4. **`get_archived_mcp_replacements`**: Retrieve the migration matrix for archived `@modelcontextprotocol/server-*` packages (`server-github`, `server-postgres`, `server-puppeteer`, `server-brave-search`, `server-redis`) and their official 2026 vendor-maintained replacements.
