# MCP Configuration

MCP config objects tell Data Designer which Model Context Protocol providers exist and which tools an LLM column may use.

[MCPProvider](#data_designer.config.mcp.MCPProvider) configures remote MCP servers via SSE or Streamable HTTP transport. [LocalStdioMCPProvider](#data_designer.config.mcp.LocalStdioMCPProvider) configures local MCP servers as subprocesses via stdio transport. [ToolConfig](#data_designer.config.mcp.ToolConfig) sets which tools are available for LLM columns and how they are constrained.

For MCP execution internals, see [Engine MCP](../engine/mcp.md). Related guides:
