Lack of query limit and pagination is problematic in large environments

I'd like to use this more, but our Prometheus is very involved, and several base queries within this tool exceed context limits for Claude Code:

● prometheus-stag101-us-east-1-eks - execute_query (MCP)(query: "kube_pod_info{namespace=\"twodotoh\"}")
  ⎿  Error: MCP tool "execute_query" response (57464 tokens) exceeds maximum allowed tokens (25000). Please use pagination, filtering, or limit parameters to reduce the response size.

### Docker container doesn't handle `TERM` and `INT` signals and continues to run after mcp server gets stopped in an IDE

## Short description

Each prometheus mcp server restart leaves it's docker container running and orphaned.

## Long description

Use following as an mcp server command configured in the `mcp.json` file:

docker run -i --rm -e PROMETHEUS_URL=http://172.17.0.1:9090 ghcr.io/pab1it0/prometheus-mcp-server:1.0.3


Stop mcp server in the IDE you use and look at the `docker ps`.
The mcp-prometheus docker container continues to run.
Each restart of the mcp server produces one more orphaned runnin

### MCP spec conformance: 9 requirement(s) violated (via @hasmcp/mcp-spec-test)

Running an automated MCP protocol conformance sweep (@hasmcp/mcp-spec-test) against this server found that it does not respond to the protocol handshake (`server/discover` / `initialize`) within the suite's 10-second timeout, even though `PROMETHEUS_URL` was set to a value the server should be able to accept without needing a live, reachable Prometheus instance for the handshake itself. Both spec revisions this server negotiates (2026-07-28 and 2025-11-25) show the same underlying symptom — no r

### No auth gate on inbound MCP connections (http/sse transport)

Looks like `PROMETHEUS_USERNAME/PASSWORD/TOKEN` authenticate the server's own connection *to* Prometheus, but there's no auth on the inbound side — anyone who can reach the http/sse endpoint can use it.

Flagging in case it's useful: [getmcpauth](https://getmcpauth.dev) does OAuth 2.1 + DCR specifically for MCP servers, could close that gap without a big refactor. Not trying to sell hard, just noticed it while looking at MCP servers with exposed HTTP transports.
