Support a tool that can call all Elasticsearch APIs

[weizijun]

In the AI Assistent，the elasticsearch tool can call all Elasticsearch APIs, the prompt is:

{
    "name": "elasticsearch",
    "description": "Call Elasticsearch APIs on behalf of the user. Make sure the request body is valid for the API that you are using. Only call this tool when the user has explicitly requested it.",
    "parameters": {
      "type": "object",
      "properties": {
        "method": {
          "type": "string",
          "description": "The HTTP method of the Elasticsearch endpoint",
          "enum": [
            "GET",
            "PUT",
            "POST",
            "DELETE",
            "PATCH"
          ]
        },
        "path": {
          "type": "string",
          "description": "The path of the Elasticsearch endpoint, including query parameters"
        },
        "body": {
          "type": "object",
          "description": "The body of the request"
        }
      },
      "required": [
        "method",
        "path"
      ]
    }
  }

Will MCP Server add this tool?

Hey @weizijun Thank you for your interest in the es mcp server.

A do-it-all Elasticsearch API tool brings risks (accidental data deletion, cluster misconfiguration). More thought needs to be put into this. Atm we're leaning toward specific, purpose-built tools that create clearer contracts with the LLM. You can expect more tools to be added to this server in the future.

Could you share specific scenarios where a general API tool would be preferred vs. specialised tools?

A common scenario is to analyze problems that occur in the cluster and fix them.
When we use LLM to analyze problems occurring in the cluster, it need to call many Elasticsearch API, the LLM has learning these API and knows which API to call.
Like:

• GET _cluster/health
• GET _cluster/allocation/explain
• GET _nodes/stats
  etc.

If all these APIs were defined in different tools, there would be too many tools.
