Why obsidian_runtime_maintenance needs a policy

The tool 'runs' operations (integrity checks, maintenance, cache refresh) against a local shared runtime. These are execution-type actions that trigger operational effects on the server's runtime state. While not purely destructive or financial, they go beyond read-only and involve active execution of maintenance routines that could affect system state.

POLICY

How to control obsidian_runtime_maintenance

PolicyLayer is an MCP gateway — it sits between your AI agents and Optimike Obsidian MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for obsidian_runtime_maintenance:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "obsidian_runtime_maintenance": {
      "limits": [
        {
          "counter": "obsidian_runtime_maintenance_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

obsidian_runtime_maintenance stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about obsidian_runtime_maintenance

What does the obsidian_runtime_maintenance tool do? +

Runs integrity checks, maintenance, or cache refresh actions for the local shared runtime. It is categorised as a Execute tool in the Optimike Obsidian MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on obsidian_runtime_maintenance? +

Register the Optimike Obsidian MCP server in PolicyLayer and add a rule for obsidian_runtime_maintenance: 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 Optimike Obsidian MCP. Nothing to install.

What risk level is obsidian_runtime_maintenance? +

obsidian_runtime_maintenance is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit obsidian_runtime_maintenance? +

Yes. Add a rate_limit block to the obsidian_runtime_maintenance 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 obsidian_runtime_maintenance completely? +

Set action: deny in the PolicyLayer policy for obsidian_runtime_maintenance. 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 obsidian_runtime_maintenance? +

obsidian_runtime_maintenance is provided by the Optimike Obsidian MCP server (optimikelabs/optimike-obsidian-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
