GroupDocs.Mcp.AzureBlob.Storage

GroupDocs.Mcp.AzureBlob.Storage

Azure Blob Storage IFileStorage implementation for the GroupDocs MCP Core framework.

Output files are exposed as time-limited SAS download URLs so MCP clients can fetch results directly from the blob container without streaming through the server.

Installation

dotnet add package GroupDocs.Mcp.Core
dotnet add package GroupDocs.Mcp.AzureBlob.Storage

Usage

Connection string

builder.Services
    .AddGroupDocsMcp()
    .AddAzureBlobStorage(options =>
    {
        options.ConnectionString = "DefaultEndpointsProtocol=https;AccountName=...;AccountKey=...";
        options.ContainerName    = "documents";
    });

Account name + key

options.AccountName   = "mystorage";
options.AccountKey    = "...";
options.ContainerName = "documents";

Managed identity / TokenCredential

options.AccountName     = "mystorage";
options.TokenCredential = new DefaultAzureCredential();
options.ContainerName   = "documents";

SAS URL generation requires the client to be able to sign — connection string / account key work out of the box; user-delegation SAS over TokenCredential requires the managed identity to hold the appropriate RBAC role.

Behaviour

• Container is created on first use if missing (CreateIfNotExists).
• Writes honor a rewrite flag; when false, colliding blob names get a (1), (2)… suffix.
• GetDownloadUrlAsync returns a SAS URL (read-only) whose expiry is controlled by McpConfig.DownloadUrlExpiry (default: 1h). Returns null if the client cannot generate SAS.
