Sets the current directory that the record output writes files to

How to control obs-set-record-directory ↓

AI agents use obs-set-record-directory to create or update resources in OBS MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OBS MCP Server environment.

Medium Risk

This tool modifies OBS state by changing the recording output directory path. It is reversible (the directory can be changed again), so it fits Write rather than Destructive. However, it has medium severity because misconfiguration could cause recordings to write to unintended locations, potentially filling disks, overwriting existing files, or storing sensitive footage in accessible directories.

From the tool's definition Tool explicitly 'Sets the current directory that the record output writes files to' - a configuration modification that changes where OBS records files.

Documented attack patterns abuse exactly the kind of access obs-set-record-directory gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and OBS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for obs-set-record-directory:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "obs-set-record-directory": {
      "limits": [
        {
          "counter": "obs-set-record-directory_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

obs-set-record-directory stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register OBS MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on obs-set-record-directory? +

Register the OBS MCP Server MCP server in PolicyLayer and add a rule for obs-set-record-directory: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches OBS MCP Server. Nothing to install.

What risk level is obs-set-record-directory? +

obs-set-record-directory is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit obs-set-record-directory? +

Yes. Add a rate_limit block to the obs-set-record-directory rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block obs-set-record-directory completely? +

Set action: deny in the PolicyLayer policy for obs-set-record-directory. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides obs-set-record-directory? +

obs-set-record-directory is provided by the OBS MCP Server MCP server (royshil/obs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every OBS MCP Server tool call.
