RESTK connects directly to your AI coding assistant. No plugins, no cloud relay, no configuration hell. You talk to your APIs in plain English, and RESTK does the rest.

This guide covers everything you can do with RESTK's AI integration — from one-click setup to advanced workflows like codebase scanning, security audits, and test generation.

Setup in 30 Seconds

Open RESTK, go to Settings → AI Integration, select your AI assistant, and click Setup. Done.

RESTK supports Claude Code, Claude Desktop, and Cursor out of the box. No Node.js, no npx, no manual JSON editing required.

For manual setup instructions, see the MCP Setup Guide.

Talk to Your APIs

Once connected, just describe what you want in plain English. Your AI assistant knows which RESTK tools and prompts to use.

Browse Your Workspace

Ask your AI assistant to explore your API data:

"Show me all my collections"
"List the requests in my Users folder"
"What environments do I have?"
"Show me the last 10 API calls I made"
"Search my history for requests that hit the /payments endpoint"

No parameters to remember. No tool names to look up. Just say what you want to see.

Run and Test Requests

Execute any saved request or ad-hoc cURL command:

"Run the Login request" — RESTK shows a confirmation dialog, then executes with full variable substitution and scripts
"Run this cURL: curl -X POST https://api.example.com/users ..." — Execute any HTTP request directly
"Re-run the Get Users request but change the page to 5" — Modify and re-execute
"Export the Create Order request as cURL" — Get a paste-ready command

Create and Organize

Build entire API collections through conversation:

"Create a new collection called Payment Gateway API"
"Create a POST request called 'Create User' in the Users folder with a JSON body containing name, email, and role"
"Set Bearer token authentication on the collection using the authToken variable"
"Import my Postman collection from the exported JSON file"

Analyze and Debug

When something breaks, let AI help you figure out why:

"How is the Create Order endpoint performing? Show me stats for the last 30 days" — Returns mean, median, P95, P99 response times and error rates
"Compare the last two responses from Get Users — what changed?"
"What error patterns are happening in my API collection this week?" — Groups errors by status code and URL pattern
"Search for 'insufficient funds' across all my API responses"

Advanced AI Workflows

This is where RESTK's AI integration goes beyond basic API tooling. These workflows combine multiple tools and prompts to handle complex tasks with a single sentence.

Scan a Codebase and Build a Collection

"Scan this codebase and create a RESTK collection with all the API endpoints"

The AI will scan your routes, controllers, and schemas. It creates an environment with the right variables, a collection with folders for each module, and every endpoint with proper URL templates, auth, sample bodies, and test scripts. It even wires up the variable flow — login captures the token, create captures the ID, downstream requests use them.

Supported frameworks include Express, NestJS, Django, Flask, Rails, Spring Boot, Laravel, and Go.

Generate Comprehensive Tests

"Write comprehensive tests for the Create User request"

The AI analyzes the request structure, parameters, and past responses, then suggests test scenarios covering:

Functional — happy path validation
Edge cases — empty values, boundary conditions, special characters
Security — injection patterns, auth bypass attempts
Error handling — invalid inputs, missing fields

"Generate security-focused test cases for the Payment endpoint"

Debug Failing Requests

"Why is the Create Order request returning 500?"

The AI gathers the request configuration, recent error responses, headers, and timing — then walks you through likely causes and fixes. Not generic advice, but analysis based on your actual request and response data.

Run a Security Audit

"Do a security review of my Payment Gateway API"

Reviews every endpoint for missing authentication, inconsistent auth patterns, missing security headers, sensitive data exposed in URLs, and HTTP endpoints that should be HTTPS. Each finding is rated by severity with specific fix recommendations.

Optimize Slow Endpoints

"Help me speed up the List Products endpoint"

Analyzes response history and suggests caching strategies, pagination improvements, compression, field selection, and timeout adjustments.

Audit API Quality

"Is my API collection ready for production?"

Evaluates authentication quality, error handling consistency, response format standardization, documentation completeness, and security practices.

Real Workflows, One Sentence at a Time

Here is how these capabilities combine in real development scenarios:

Starting a new project: Just say "Scan this codebase and create a RESTK collection" and the AI does everything.

Debugging production errors: "What errors are happening in my API this week?" → "Help me debug the failing Payment request" → "Show me the error timeline for that request"

Writing tests before shipping: "Write comprehensive tests for the Create Order request" → "Add those tests to the request" → "Run it to verify the tests pass"

Preparing for launch: "Do a security review of my API" → "Score my API's readiness for production"

Speeding up a slow endpoint: "Show me performance stats for List Products over the last month" → "Help me speed up that endpoint"

Privacy by Default

Your data never leaves your machine through the AI connection:

Credentials, API keys, and secrets are never shared with AI
Only collections you explicitly share are visible
Response content is sanitized before AI sees it
All operations are logged in the audit trail
Everything stays local
