Add OpenSearch MCP Server

[ylwu-amzn]

Is your feature request related to a problem? Please describe.
We propose adding a new OpenSearch MCP server to this repository. This server would act as a bridge between MCP clients and OpenSearch clusters, allowing standardized interaction with OpenSearch's REST APIs through the Model Context Protocol.

Describe the solution you'd like

• Build a new MCP server for OpenSearch, a popular search and analytics engine
• Provide a standardized way for MCP clients to interact with OpenSearch
• Enable powerful search and analytics capabilities through the MCP interface

Describe alternatives you've considered
N/A

Additional context

• Authentication and security between MCP server and OpenSearch clusters
• Mapping MCP operations to appropriate OpenSearch API calls
• Error handling and translation between OpenSearch and MCP
• Version compatibility with different OpenSearch releases

Thanks for creating this issue, MCP being adopted by OpenAI and Anthropic will result in wider usage going forward. This will allow seamless integration of OpenSearch data into agentic workflows.

Few follow up questions:

• What feature sets will be supported using OpenSearch MCP servers?
• What is the plan with existing tools/skills repositories, will they be refactored to adopt MCP?
• Will the MCP server be accessible through opensearch service?

What feature sets will be supported using OpenSearch MCP servers?

We plan support OpenSearch REST APIs, like search

What is the plan with existing tools/skills repositories, will they be refactored to adopt MCP?

The existing skills repo will still be there. The default tool integration through skill repo provide easier experience.

Will the MCP server be accessible through opensearch service?

Yes

Hi, thanks for the feature request. This repo is limited to a smaller set of servers at the moment for maintenance overhead reasons. Looking at the Readme, it looks like there is now an official one added to the list:

OpenSearch Logo OpenSearch - MCP server that enables AI agents to perform search and analytics use cases on data stored in OpenSearch.

Or, if you have a community server implementation you'd like to add to the list in the Readme, please feel free to open a PR to add a link. Thanks!
