REST, GraphQL & an MCP server for AI agents
The API client that lives in your editor
Send REST and GraphQL requests, organize them into collections, and let AI agents build and test them for you. Works in Cursor, VS Code, Windsurf, and other editors. No account required.
Runs inCursor · VS Code · Windsurf · VSCodium · and any VS Code-compatible editor
Everything you need to test and debug APIs
All HTTP methods, query params with URL sync, headers, and body types: JSON, form, multipart with file uploads, and plain text.
Dedicated query and variables editor. Auto-sets POST and the JSON content type. Saved GraphQL requests reload into the two-pane editor.
Generate cURL, JavaScript fetch, Python requests, or Node.js axios from any request with one click. Copy to clipboard instantly.
Organize requests into collections and nested folders. Import from Postman v2.x, Thunder Client, and OpenAPI 3.x / Swagger 2.0.
An MCP server lets Claude Code, Cursor, and other agents build, run, and save API requests as real collections in your project.
Your AI agent tests APIs. Now it can save that work.
Coding agents test endpoints with throwawaycurlcommands that vanish when the session ends, so you rebuild every request by hand. Gud API ships anMCP serverthat turns that testing into something you keep.
The agent builds an endpoint, runs it, and saves the request and the response as a real collection in your project's.gud-api/folder. It appears in your sidebar while the agent works, keeps the responses it captured, and commits to git so it reviews in the pull request next to the code.
// .mcp.json: drop this in your project and your agent can build collections { "mcpServers": { "gud-api": { "command": "npx", "args": ["-y", "@gudlab/gud-api-mcp", "--project", "."] } } }
Install the extension inCursor, Windsurf, VSCodium, Antigravity, Trae, and other VS Code-compatible editors fromOpen VSX, or inVS Codefrom theMarketplace. The MCP server works with any MCP client: Claude Code, Cursor, Windsurf, Codex, Cline, Zed, and more.
Other API clients keep shrinking their free tier: collection caps, forced accounts, features moving behind a subscription. Gud API goes the other way. The free tier isn't a teaser, it's the full product. Unlimited requests, unlimited collections, no account. Pro is optional, and only adds cloud sync and unlimited environments for people who want them.
Coming from another client? Seevs Thunder Client,vs Postman,vs Bruno, or thefull comparison matrix. Gud API imports from all of them, and you can paste a cURL command from anywhere to build a request in seconds.
The free tier isn't a teaser, it's the full product. Pro adds cloud sync. Team adds shared collections.
The core product is free with no limits and no account. If it saves you time, you can support development directly.
