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

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

## Why set_public_session_visibility is rated Medium

This tool creates or modifies data access controls reversibly. While it doesn't create new data or delete anything, it changes the accessibility/publication state of existing case cards. This is a Write operation (modifies data properties) rather than Read (query-only) or Destructive (irreversible deletion).

From the tool's own definition: "Tool explicitly modifies visibility settings ('Explicit consent toggle') of session data from private to public, allowing data state changes that affect who can access case information."

## Use case

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

## Recommended policy (PolicyLayer)

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