MOST DANGEROUS TOOLS

High Risk

The most dangerous Temporal tools

Execute · Medium temporal.workflow.query While 'query' sounds like a read operation, in Temporal a workflow query invokes a named query handler on a running workflow execution. Write · Medium docs.refresh This tool modifies the local documentation corpus by syncing/updating it with new content.

2 of Temporal's 28 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Temporal

PolicyLayer is an MCP gateway — it sits between your AI agents and Temporal, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "docs.refresh": {
    "limits": [
      {
        "counter": "docs.refresh_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "docs.get": {
    "limits": [
      {
        "counter": "docs.get_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Temporal — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Temporal

How do I prevent bulk modifications through Temporal? +

The Temporal server has 1 write tools including docs.refresh. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Temporal.

How many tools does the Temporal MCP server expose? +

28 tools across 1 categories: Read. 26 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on Temporal? +

Register the Temporal MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Temporal tool call.

Deterministic rules across all 28 Temporal tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
