Gud Api Mcp
io.github.gudlabPublished by GitHub account gudlabv0.1.3Updated Oct 24, 2026
AI agents create, run, and save API requests as Gud API collections in your project.
Overview
Lets an AI assistant create, run, and save HTTP API requests as Gud API collections inside a project.
- What you can do
- The Gud API MCP server connects an assistant to the Gud API client so it can build API requests, execute them, and store them as real collections in the project. The companion editor extension supports REST and GraphQL requests, environments and variables, response inspection, code generation, history, cookies, and imports from Postman, Thunder Client, and OpenAPI specs. The MCP server itself is published as the npm package @gudlab/gud-api-mcp and runs locally over stdio.
- When to use it
- Useful when you want an assistant to exercise or document an HTTP API and keep the resulting requests as organized, reusable collections in your project rather than ad-hoc commands. It fits teams already using the Gud API editor extension who want agent-driven request creation and execution.
- Requirements
- Runs as a local process over stdio, started with npx from the npm package @gudlab/gud-api-mcp, typically with a project path argument. Node.js and network access to the target APIs are needed. No authentication, environment variables, or headers are declared for the MCP server.
Installation
In SourceWeft
- Open Gud Api Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
README
Gud API
A lightweight, full-featured API client built into your editor. Test REST and GraphQL APIs, organize requests into collections, manage environments, and generate code snippets — without switching to Postman or another external tool.
Install from Open VSX or the VS Code Marketplace. Site: gudapi.gudlab.org.
Source
The editor extension is proprietary. This repository is the public home for product docs and issues. It does not contain the VS Code / Open VSX extension source.
If you followed the GitHub link from the Marketplace or Open VSX, you are in the right place for bugs and feature requests. There is nothing here to clone for the UI.
The companion MCP server is public: @gudlab/gud-api-mcp, source in gudlab/gud-api-mcp. Docs: gudapi.gudlab.org/guide/ai-agents.

- File uploads via multipart form-data with native file picker
- Auth: Bearer Token, Basic Auth, API Key (header or query param)
GraphQL
- Dedicated GraphQL editor with separate Query and Variables panes
- Auto-sets method to POST and Content-Type to application/json
- Variables parsed as JSON and sent alongside the query
Response Viewer
- Status code, response time, size, and format detection (JSON/HTML/XML)
- Pretty / Raw / Preview toggle — preview renders HTML in a sandboxed iframe
- Search — find text in the response body with match count and navigation
- Cookies tab — view Set-Cookie headers from the response
- Copy button for body or headers
Code Generation
- Generate code from any request with one click
- Languages: cURL, JavaScript (fetch), Python (requests), Node.js (axios)
- Copy to clipboard
Request History
- Every request is auto-saved to history (last 100 entries)
- View history in the sidebar with method, URL, status, and timestamp
- Click any entry to reload it into the request builder
- Persists across VS Code sessions
Cookie Management
- Cookies from responses are automatically captured and stored
- Cookies are auto-sent on subsequent requests to matching domains
- Cookie Manager to view, enable/disable, and delete cookies by domain
- In-memory storage — cookies reset when VS Code restarts
Collections
- Save and organize requests into collections and folders
- Click to load any saved request back into the builder
- Right-click to rename, delete, or create new folders
- Supports deeply nested folder structures
Import
- Postman v2.x collections (including nested folders, headers, body, and collection variables)
- Thunder Client collections
- OpenAPI 3.x / Swagger 2.0 specs (paths become requests, tags become folders)
- Import via sidebar button or command palette
Environments & Variables
{{variable}}syntax in URLs, headers, and body — resolved automatically on send- Collection-level variables imported from Postman (e.g.
{{base_url}}) - User-defined environments with key-value editor and enable/disable toggles
- Environment selector in the toolbar — switch between environments instantly
- Variable resolution order: environment overrides collection variables
Editor Integration
- Activity bar icon for quick access
- Matches your VS Code theme automatically (light, dark, high contrast)
- Works without a workspace open (stores in VS Code global storage)
- Keyboard shortcut: Enter to send request
Getting Started
- Install the extension from Open VSX or the VS Code Marketplace
- Click the Gud API icon in the activity bar
- Enter a URL and press Send
- Click Save to add the request to a collection
To import an existing collection, click Import in the sidebar and select a Postman, Thunder Client, or OpenAPI JSON file.
MCP for AI agents
Agents can create, run, and save requests as real Gud API collections via @gudlab/gud-api-mcp:
