Features
Embedding & Sharing
Embed a live playground in your documentation, share reproducible execution links with colleagues, and add a README badge so developers can test your server with one click.
Shareable execution links
Every execution in the Playground can be shared as a URL that auto-connects to the server, selects the tool, pre-fills arguments, and optionally auto-executes. Use these in bug reports, docs, or team Slack.
URL format
https://mcpplayground.tech/playground?url=SERVER_URL&tool=TOOL_NAME&args=BASE64_JSON&autorun=1
urlThe MCP server URL to connect to.
toolPre-selects a specific tool by name.
argsBase64-encoded JSON object of tool arguments to pre-fill.
autorunSet to "1" to auto-execute the tool immediately after connecting. Requires both tool and args.
Example — pre-filled auto-run link
This link opens the DeepWiki server, selects the ask_question tool, and auto-runs immediately:
https://mcpplayground.tech/playground?url=https://mcp.deepwiki.com/mcp&tool=ask_question&autorun=1
Generate a share link in the UI
In the Playground, click the Share button in the toolbar. If a result is visible, it generates a link with autorun=1 that reproduces your exact execution. Without a result, it generates a link that pre-fills the tool and arguments only.
Embedding in documentation
Use the /embed route to embed an interactive Playground in your docs site, README, or any page that allows iframes.
