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

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

## Why mcp_edit is rated Medium

This tool creates or modifies MCP server configuration, which is reversible data modification. It does not delete (would be Destructive), execute arbitrary code (would be Execute), or move financial assets (would be Financial). However, severity is high because misconfigured MCP servers could compromise the integrity of connected AI assistants and expose sensitive credentials or capabilities to unauthorized access.

From the tool's own definition: "Tool name 'mcp_edit' and description 'Edit MCP server configuration' directly indicate modification of configuration data."

## Use case

AI agents use mcp_edit to create or update resources in 1MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 1MCP Server environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches 1MCP Server:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
