It demonstrates the XAA token-exchange flow and shows how to implement a secure MCP client in C# with an MCP SDK. ### Source excerpt A few years ago, getting a user signed in to an application or multiple applications with Single Sign-On (SSO) was enough; OpenID Connect (OIDC) handled the login, JWTs carried the claims, and Proof Key for Code Exchange (PKCE) made it secure. Today, with evolving AI, agents act on behalf of users and seek multiple accesses across different resources to execute a task. And that is when you'll hit the gap. The user has an identity, but the downstream service--like a Model Context Protocol (MCP) server, an API, or an agent tool has no way to trust it: the ID Token that proves the user's identity for your app, not for that service. You need a way to take that identity and have it trusted further down the chain, in line with the org's policy, without asking the user to log in again. Cross App Access (XAA) solves exactly that. The user authenticates once. The Identity Provider (IdP) evaluates the enterprise policy and issues a signed Identity Assertion. The downstream service exchanges that assertion for a scoped Bearer token. In this post, we'll explore how Cross App Access (XAA) closes the trust gap, test the flow using an XAA playground, and implement a secure MCP client in just a few lines of C# using our dedicated SDK.

Before we start implementing and building the application, it is important to understand the mechanics of Cross App Access (XAA). At its core, XAA is an open standard that securely enables AI agents to act on behalf of a user and communicate with downstream applications without requiring constant, manual user consent. While the flow is sophisticated, it relies on two standard interactions: RFC 8693 (Token Exc ## Getting Started With Queryable Encryption in the MongoDB C# Driver DevFeed: [Getting Started With Queryable Encryption in the MongoDB C# Driver]() Original publisher: [Read original article]() Author: Luce Carter Published: 2025-04-22T12:00:00Z Content type: tutorial Language: en Sources: [Nic Raboy]() Topics: [Library](), [Encryption](), [C#](), [.NET](), [Cryptography](), [data](), [Security]() Tags: [atlas](), [c-sharp](), [csharp](), [data](), [dotnet](), [encryption](), [getting-started](), [github](), [macos](), [mongodb](), [net](), [security](), [tutorial](), [windows]() ### AI overview A tutorial on adding MongoDB Queryable Encryption to a healthcare application using the MongoDB C# driver.

It uses the DTE TextEditor CSharp InsertTabs property and provides keyboard-accessible macro commands. ### Source excerpt I work at several projects at a time, and I have different settings/requirements concerning the code style for each of them. The main issue is 'Tabs vs. Spaces' option - the first project requires using tabs, the second - spaces. It's obvious that going Tools -> Settings -> ... is not an option for everyday use. Sounds like a good task for the automation macros, right? Navigate to Tools -> Macros -> Macros IDE (or use Alt+F11) Create new macros in Project Explorer (Project - Add Module) Write a method that changes the indentation settings: Public Module TabsModule Public Sub ToggleTabs() Dim currentSetting As Boolean = DTE.Properties("TextEditor", "CSharp").Item("InsertTabs").Value DTE.Properties("TextEditor", "CSharp").Item("InsertTabs").Value = Not currentSetting End Sub End Module Now you can use Macros Explorer (Alt+F8, also you can dock it as one of your panels) to quickly change settings (by double-clicking on the corresponding item name in the macros tree)
