Playground

The Playground is an interactive chat interface where you can test your MCP server tools without setting up a full client. It is available on Starter and Pro plans.

Prerequisites​

You need an API key from the model provider you want to use (Anthropic, OpenAI, or Google). Enter it in the Playground settings before starting a session.

Starting a session​

  1. Navigate to Playground in the sidebar.
  2. Open settings and enter your provider API key.
  3. Select a model from the model picker. Bloque supports models from Anthropic, OpenAI, and Google.
  4. The Playground connects to the MCP Proxy for your active Hub. The header shows how many MCP servers are connected.
  5. Type a message. When the model decides to call an MCP tool, the Playground executes it and shows the result inline.

Switching models​

Use the Switch Model button in the header to change models mid-session. You can also open Settings to configure temperature and max tokens.

Ending a session​

Click Stop Session to disconnect from the MCP Proxy and clear the conversation.

Notes​

  • The Playground connects to the MCP Proxy only — it does not run stdio MCP servers locally in your browser.
  • Tool calls are logged and visible on the Logs page.
  • The Playground is not available on the Free plan. Upgrade to Starter or Pro to access it.
