 [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) is an open protocol standard that provides a standardized way for AI models to connect to external data sources and tools. OpenSearch integrates with MCP, enabling agents to use external tools and data sources through MCP servers.
 
 Connecting to external MCP servers expands agent capabilities to include the following functionality:

 OpenSearch supports agentic workflows using [agents]({{site.url}}{{site.baseurl}}/ml-commons-plugin/agents-tools/agents/). While OpenSearch provides built-in tools for running complex queries, [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) enables integration with external tools and data sources. MCP is an open protocol standard that provides a standardized way for AI models to connect to external data sources and tools, acting as a "universal adapter" for remote MCP server tools.
 
 Currently, OpenSearch only supports MCP servers that use the Server-Sent Events (SSE) protocol. Standard Input/Output (`stdio`) protocol is not supported.
