Cline is an open-source coding agent that runs as IDE extensions and a CLI, and its MCP client is tool-focused: external MCP servers add custom tools beyond Cline's built-ins. Servers connect over stdio for local processes, streamable HTTP (which the docs recommend) for remote ones, and legacy SSE for backward compatibility.

Configuration has three doors: hand-editing ~/.cline/mcp.json, the IDE's MCP Servers panel, or the cline mcp wizard in the CLI. The documentation names no MCP spec revision, so revision support is recorded as unknown.

How was this verified, and what are the sources?
