Configure persistent plugins from a prompt

English | 中文

Creator mode provides Plugin Manager and read-only runtime inspection. Plugin configuration belongs to the current profile, affects its sessions, and survives process restarts.

Connect an MCP server

Start the Web profile and select Creator mode. With a reachable Streamable HTTP MCP server that exposes ping, send this prompt using its actual endpoint:

Configure the MCP server at <endpoint> in this profile as demo. Make its tools available now, then call its ping tool and tell me the result.

The agent writes a configuration-only bundle whose patch inserts @deepseek-ai/dsh-mcp-client, then installs it with plugin_manager install_bundle. With HMR enabled, the tools appear in the same running session. Verify both the management result (application: applied) and a successful mcp__demo__ping call. A saved entry with restart-required has not activated yet; a failed entry needs configuration repair.

Read the bundle patch before editing its configuration. Use Plugin Manager to disable entries or remove the bundle. See the MCP client reference for accepted configuration and connection failure behavior.
