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

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "mmp_read",

## Why mmp_read is rated Low

This tool retrieves or queries data from the knowledge storage without any side effects, modification, or execution. The 'read only' language confirms it performs data retrieval operations. Despite being part of a system with write/update capabilities (mmp_create, mmp_update), this specific tool is restricted to read-only access, placing it in the Read category with low severity.

From the tool's own definition: "Tool name 'mmp_read' and description 'Read only the requested MMP body blocks' explicitly indicate retrieval of data with no modification capability."

## Use case

AI agents call mmp_read to retrieve information from Pypi:dense Knowledge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Pypi:dense Knowledge:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "mmp_read": {}
  }
}
```
