MCP config objects tell Data Designer which Model Context Protocol providers exist and which tools an LLM column may use.
MCPProvider configures remote MCP servers via SSE or Streamable HTTP transport. LocalStdioMCPProvider configures local MCP servers as subprocesses via stdio transport. ToolConfig sets which tools are available for LLM columns and how they are constrained.
For MCP execution internals, see Engine MCP. Related guides:
