Keboo.Mcp.linux-arm64

Keboo.Mcp

Local stdio MCP server for Microsoft Teams chat workflows.

Current tools

The first tool set is focused on Microsoft Teams chats:

Requirements

1. .NET 10 SDK
2. A Microsoft Entra app registration for delegated Microsoft Graph access
3. A work or school Microsoft 365 account

Microsoft Teams chat APIs used here don't support personal Microsoft accounts for these delegated flows.

Required Microsoft Graph delegated permissions

Grant these delegated permissions to the app registration used by the server:

• User.Read
• Chat.Read
• Chat.Create
• ChatMessage.Send

ListChats uses Chat.Read. SendDirectMessage uses Chat.Create plus ChatMessage.Send. The server uses delegated auth, so actions happen as the signed-in user.

Configure the server

The server reads configuration from either user secrets or environment variables.

Option 1: user secrets

dotnet user-secrets set "KebooMcp:Graph:TenantId" "<tenant-id>" --project .\Keboo.Mcp\Keboo.Mcp.csproj
dotnet user-secrets set "KebooMcp:Graph:ClientId" "<client-id>" --project .\Keboo.Mcp\Keboo.Mcp.csproj
dotnet user-secrets set "KebooMcp:Graph:AuthenticationMode" "InteractiveBrowser" --project .\Keboo.Mcp\Keboo.Mcp.csproj

Option 2: environment variables

$env:KebooMcp__Graph__TenantId = "<tenant-id>"
$env:KebooMcp__Graph__ClientId = "<client-id>"
$env:KebooMcp__Graph__AuthenticationMode = "InteractiveBrowser"

Authentication modes

The token cache is persisted locally under the default cache name Keboo.Mcp. You can override it with KebooMcp__Graph__TokenCacheName.

Run locally

dotnet run --project .\Keboo.Mcp\Keboo.Mcp.csproj

Run from NuGet

dnx [email protected] --yes

The NuGet package includes an embedded .mcp/server.json manifest so MCP clients can discover the stdio transport and prompt for the required KebooMcp__Graph__TenantId and KebooMcp__Graph__ClientId environment variables.

Example MCP client configuration

This repo includes a root .mcp.json file so clients that support repository-scoped MCP configuration can discover the server automatically.

If you need to add it manually, use this shape:

  "servers": {
    "keboo-mcp": {
      "type": "stdio",
      "command": "dotnet",
      "args": [
        "run",
        "--project",
        "Keboo.Mcp\\Keboo.Mcp.csproj"
      ],
      "env": {
        "KebooMcp__Graph__AuthenticationMode": "InteractiveBrowser"
      }
    }
  }
}
