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

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

## Why update is rated Medium

This tool modifies project dependencies by updating lock files, which is a Write operation. It changes dependency versions/configurations but is reversible (the previous lock file state could be restored). The impact is medium severity as incorrect updates could break builds or introduce incompatible versions, affecting the project but with limited blast radius outside the development environment.

From the tool's own definition: "Tool description states 'Updates dependencies in the lock file' and 'Optionally updates a single package', indicating modification of existing data (the lock file) in a reversible manner."

## Use case

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

## Recommended policy (PolicyLayer)

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

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