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

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

## Why memory_link is rated Medium

Without explicit documentation, we infer 'memory_link' likely creates or modifies relationships in the memory store (a Write operation). The blast radius is medium because unauthorized linking could corrupt memory associations used for agent decision-making, but effects are reversible via other memory management tools.

From the tool's own definition: "Tool is named 'memory_link' with empty description, suggesting it creates associations or links in memory state. Sibling tools like 'memory_add' (Write), 'memory_consolidate' (Write), and 'memory_share' (Write) indicate this server modifies stored memory."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "memory_link": {
      "limits": [
        {
          "counter": "memory_link_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`
