Increment a session-scoped counter to verify state continuity

Agent View of the PolicyLayer registry record for `increment-counter`. HTML page: https://policylayer.com/tools/frontmcp/increment-counter

## Facts

- Tool: `increment-counter`
- Server: Frontmcp (`agentfront/frontmcp`) — https://policylayer.com/tools/frontmcp.md
- Homepage: https://github.com/agentfront/frontmcp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "increment-counter",
    "arguments": {}
  }
}
```

## Why increment-counter is rated Medium

The tool modifies a counter value (incrementing it), which is a write operation. It is session-scoped, meaning its blast radius is limited to a single session. The purpose is state verification, not destructive or financial in nature. Confidence is slightly reduced because the description is minimal and the actual implementation could vary.

From the tool's own definition: "Increment a session-scoped counter to verify state continuity"

## Use case

AI agents use increment-counter to create or update resources in Frontmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frontmcp environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Frontmcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "increment-counter": {
      "limits": [
        {
          "counter": "increment-counter_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
