# config_set

Set configuration value Use when native settings.json edits are wrong because the values need to be read by the Ruflo runtime (daemon, MCP server, neural router) — those load via the config_* path, not by re-reading settings.json. For .gitignore / .editorconfig style files, native Edit is fine.

## Facts

- Tool: `config_set`
- Server: Claude Flow (`claude-flow`) — https://policylayer.com/tools/io-github-ruvnet-claude-flow.md
- Install: `npx -y claude-flow`
- Homepage: https://github.com/ruvnet/claude-flow
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why config_set is rated Medium

The tool creates or modifies configuration data that affects runtime behavior of critical infrastructure components (daemon, MCP server, neural router). While reversible (configurations can be changed), this is a Write operation rather than Read.

From the tool's own definition: "Tool description states 'Set configuration value' and explicitly indicates it modifies runtime configuration that is 'read by the Ruflo runtime (daemon, MCP server, neural router)'. This is a write operation that modifies system configuration."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "config_set": {
      "limits": [
        {
          "counter": "config_set_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`
