Overview

AI-generated overview

Remote MCP server that parses OpenAPI and GraphQL schemas, renders an interactive API playground, executes live HTTP requests, and generates code snippets.

What you can do
  • Parse OpenAPI 3.x schema objects or GraphQL SDL into structured endpoint and type lists
  • Render self-contained interactive HTML playgrounds with try-it-out forms for a set of endpoints
  • Execute live HTTP requests to external URLs and return real status, headers and response body
  • Generate ready-to-run request snippets in JavaScript, TypeScript, Python, curl, Go, Ruby, PHP or Java
  • Read invocation history for a tool within the current Worker instance
When to use it
Useful when exploring or documenting an API from its OpenAPI or GraphQL schema, trying endpoints out, and turning requests into code in a chosen language. Suited to API exploration and client prototyping rather than production traffic.
Requirements
A remote streamable HTTP endpoint; no package, environment variables or headers are declared. The executor needs outbound network access to the target API, and any authentication for those APIs must be supplied in the request itself.
Before you install
The executor sends real HTTP requests to external URLs, which can change or delete remote data and may expose credentials placed in requests; private IPs are blocked. Invocation history is per Worker instance and resets on cold start, so it is not durable.

Installation

In SourceWeft

  1. Open Interactive Api Playground in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.lazymac2x%2Finteractive-api-playground/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
