# filter

Filter notifications to, use default unless specified. Read notifications are ones that have already been acknowledged by the user. Participating notifications are those that the user is directly involved in, such as issues or pull requests they have commented on or created. (string, optional)

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

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

## Why filter is rated Low

This is a filtering/querying tool that helps users retrieve and categorize existing notifications. It does not create, modify, delete, or execute any operations - it only retrieves notification metadata already present in GitHub. The blast radius of misuse is minimal as it only affects what notifications are displayed to the user, with no persistent changes to data or systems.

From the tool's own definition: "Tool filters notifications with read status and participating status - it retrieves and queries notification data."

## Use case

AI agents call filter to retrieve information from GitHub 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 GitHub:

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

## 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`
