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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why register_interest is rated Medium

This tool creates a new interest record in the system—a reversible write operation. It does not retrieve data (Read), execute arbitrary code (Execute), permanently delete anything (Destructive), or move money (Financial). The blast radius is minimal: worst case, a user is added to a notification list, which is easily reversible and poses no security or operational risk.

From the tool's own definition: "Tool description states it registers demand and includes a contact channel, indicating it creates or modifies a record in the system (an interest registration entry)."

## Use case

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

## Recommended policy (PolicyLayer)

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

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