Playground

Overview

The Playground (Cmd+3) lets you interact with any discovered MCP server directly — without going through an AI client. This is useful for testing servers during development, exploring their capabilities, and debugging specific tool calls.

Connecting to a Server

Select a server from the dropdown at the top of the Playground. Conduit connects to the server using a short-lived session: it spawns the server, runs initialize, issues your request, and then disconnects.

Both stdio and HTTP/SSE servers are supported.

Browsing Tools

The Tools tab lists all tools exposed by the server via tools/list. Each tool shows:

• Tool name
• Description
• Input schema (the JSON Schema defining expected arguments)

Invoking Tools

Click a tool to open the Tool Invoker:

1. An auto-generated form is built from the tool’s inputSchema
2. Fill in the arguments
3. Click Run
4. The response appears in the Response View with syntax-highlighted JSON

Tip

The form generator handles nested objects, arrays, enums, and required/optional fields. For complex schemas, you can also switch to raw JSON input.

Browsing Resources

The Resources tab lists all resources from resources/list. Each resource shows:

• URI
• Name and description
• MIME type

Click a resource to read its content, which is displayed in the Response View.

Prompts

The Prompts tab lists available prompts from prompts/list. Select a prompt, fill in its declared arguments, and run it to see the rendered prompt messages.
