Microsoft.Extensions.AI Integration

Cross-SDK comparison

See the centralized MEAI documentation for feature matrices and comparisons across all tryAGI SDKs.

The Braintrust SDK provides AIFunction tool wrappers compatible with Microsoft.Extensions.AI. These tools can be used with any IChatClient to give AI models access to Braintrust's prompt management and experiment tracking capabilities.

Available Tools

Method	Tool Name	Description
AsListProjectsTool()	ListProjects	Lists available projects
AsListPromptsTool()	ListPrompts	Lists prompt templates, optionally filtered by project
AsGetPromptTool()	GetPrompt	Retrieves a specific prompt by slug
AsListExperimentsTool()	ListExperiments	Lists experiments, optionally filtered by project

Usage

using Braintrust;
using Microsoft.Extensions.AI;

// Create the Braintrust client
var braintrust = new BraintrustClient(apiKey);

// Create tools
var tools = new AIFunction[]
{
    braintrust.AsListProjectsTool(),
    braintrust.AsListPromptsTool(),
    braintrust.AsGetPromptTool(),
    braintrust.AsListExperimentsTool(),
};

// Use with any IChatClient (OpenAI, Anthropic, etc.)
IChatClient chatClient = /* your chat client */;

var response = await chatClient.GetResponseAsync(
    "List all my Braintrust projects and their prompts.",
    new ChatOptions { Tools = tools });
