th0th_reindex

THE RISK

High Risk

This tool triggers a reindexing operation on a project workspace, which is an external operation that rebuilds index data. While it doesn't delete user data, it forces a potentially expensive rebuild operation that overwrites existing index state. It fits Execute since it triggers an external process whose effects depend on the project state, rather than simply reading or writing discrete data records.

From the tool's definition Force full reindex of a project workspace. Use when autoReindex (max 50 files) is insufficient after a large refactor.

HOW TO CONTROL TH0TH_REINDEX

PolicyLayer is an MCP gateway — it sits between your AI agents and Th0th, and nothing reaches the server without passing your rules. This is the rule we recommend for th0th_reindex:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "th0th_reindex": {
      "limits": [
        {
          "counter": "th0th_reindex_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

th0th_reindex 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 Th0th — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the th0th_reindex tool do? +

Force full reindex of a project workspace. Use when autoReindex (max 50 files) is insufficient after a large refactor. It is categorised as a Execute tool in the Th0th MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on th0th_reindex? +

Register the Th0th MCP server in PolicyLayer and add a rule for th0th_reindex: 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 Th0th. Nothing to install.

What risk level is th0th_reindex? +

th0th_reindex is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit th0th_reindex? +

Yes. Add a rate_limit block to the th0th_reindex 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 th0th_reindex completely? +

Set action: deny in the PolicyLayer policy for th0th_reindex. 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 th0th_reindex? +

th0th_reindex is provided by the Th0th MCP server (s1lv4/th0th). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Th0th tool call.
