# 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: Ruflo (`ruvnet/ruflo`) — https://policylayer.com/tools/ruflo.md
- Homepage: https://github.com/ruvnet/ruflo
- 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

This tool creates or modifies configuration data that affects the behavior of core Ruflo runtime components (daemon, MCP server, neural router). While reversible (configurations can be changed again), it has significant blast radius—misconfigured values could disrupt swarm coordination, agent behavior, RAG integration, or system stability.

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

## Use case

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

## Recommended policy (PolicyLayer)

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

```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`
