Druid Mcp Server

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

Required prerequisites (do these first if not already done):
- **Apache Druid cluster** — You need a running Apache Druid cluster (router + coordinator). (https://druid.apache.org/)

Canonical MCP server config (stdio transport):
- command: `docker`
- args: ["run","--rm","-i","-e","DRUID_ROUTER_URL","-e","DRUID_COORDINATOR_URL","-e","DRUID_AUTH_USERNAME","-e","DRUID_AUTH_PASSWORD","-e","DRUID_SSL_ENABLED","-e","DRUID_SSL_SKIP_VERIFICATION","-e","DRUID_MCP_READONLY_ENABLED","iunera/druid-mcp-server:latest"]
- required environment variables:
  - `DRUID_ROUTER_URL`: URL of the Druid router (e.g. http://localhost:8888). (example: `<your-druid-router-url>`)
- optional environment variables:
  - `DRUID_COORDINATOR_URL`: URL of the Druid coordinator (e.g. http://localhost:8081). (example: `<your-druid-coordinator-url>`)
  - `DRUID_AUTH_USERNAME`: Username for Druid basic auth, if enabled. (example: `<your-druid-username>`)
  - `DRUID_AUTH_PASSWORD`: Password for Druid basic auth, if enabled. (example: `<your-druid-password>`)
  - `DRUID_SSL_ENABLED`: Enable SSL for Druid connections (true/false). (example: `false`)
  - `DRUID_SSL_SKIP_VERIFICATION`: Skip SSL certificate verification (true/false). Only for testing. (example: `false`)
  - `DRUID_MCP_READONLY_ENABLED`: Enable read-only mode (true/false). (example: `false`)

Note: Spring Boot MCP server for Apache Druid. Docker is the simplest path; also runnable as `java -jar druid-mcp-server-*.jar` and supports STDIO, SSE, and Streamable HTTP transports.

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.
