What bitmap_pos does on Prometheus MCP Server

AI agents call bitmap_pos as a supporting operation in Prometheus MCP Server workflows.

Why bitmap_pos needs a policy

With no description available and an ambiguous name ('bitmap_pos' could refer to bitmap position lookup, which might be a read operation), there is insufficient information to confidently classify this tool. The name does not suggest destructive, financial, or execute-level risk. Defaulting to Other with low confidence due to the empty description.

From the tool's definition Tool name is 'bitmap_pos' with an empty description. The name alone does not clearly indicate read, write, execute, destructive, or financial operations.

Documented attack patterns abuse exactly the kind of access bitmap_pos gives an agent:

How to control bitmap_pos

PolicyLayer is an MCP gateway — it sits between your AI agents and Prometheus MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for bitmap_pos:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "bitmap_pos": {
      "limits": [
        {
          "counter": "bitmap_pos_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

bitmap_pos gets a rate cap, and everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Prometheus MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on bitmap_pos? +

Register the Prometheus MCP Server MCP server in PolicyLayer and add a rule for bitmap_pos: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Prometheus MCP Server. Nothing to install.

What risk level is bitmap_pos? +

bitmap_pos is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit bitmap_pos? +

How do I block bitmap_pos completely? +

Set action: deny in the PolicyLayer policy for bitmap_pos. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides bitmap_pos? +

bitmap_pos is provided by the Prometheus MCP Server MCP server (awslabs.prometheus-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Prometheus MCP Server tool call.

Start from Prometheus MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
