Elasticsearch

Please install the `elasticsearch` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Node.js and npx** — Requires Node.js runtime with npx to run the package. (https://nodejs.org/)
- **Elasticsearch instance with valid license** — An accessible Elasticsearch cluster (5.x-9.x) with a valid trial/platinum/enterprise license.

Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["@tocharianou/elasticsearch-mcp"]
- required environment variables:
  - `ES_URL`: Your Elasticsearch instance URL. (example: `<your-elasticsearch-url>`)
- optional environment variables:
  - `ES_API_KEY`: Elasticsearch API key for authentication (preferred alternative to username/password). (example: `<your-elasticsearch-api-key>`)
  - `ES_USERNAME`: Elasticsearch username for basic auth. (example: `<your-elasticsearch-username>`)
  - `ES_PASSWORD`: Elasticsearch password for basic auth. (example: `<your-elasticsearch-password>`)
  - `ES_CA_CERT`: Path to custom CA certificate for Elasticsearch SSL/TLS. (example: `<path-to-ca-cert>`)
  - `NODE_TLS_REJECT_UNAUTHORIZED`: Set to 0 to disable SSL certificate validation (dev/test only). (example: `0`)
  - `MCP_TRANSPORT`: Transport mode: stdio (default) or http. (example: `stdio`)
  - `MCP_HTTP_PORT`: HTTP server port when using HTTP transport. (example: `3000`)
  - `MCP_HTTP_HOST`: HTTP server host when using HTTP transport. (example: `localhost`)

Note: Supports ES 5.x-9.x with automatic version detection. Also supports HTTP streamable mode via MCP_TRANSPORT=http. Requires valid Elasticsearch license.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
