THE RISK

Medium Risk

Why set_autonumber_seed needs a policy

Setting an autonumber seed modifies configuration data (the starting value for auto-generated numbers). This is reversible in the sense that the seed can be changed again, making it a Write operation. However, misuse could cause duplicate number generation or gaps in sequences, which could have downstream business impact, warranting medium severity.

From the tool's definition 'Sets the seed value for an AutoNumber column' — modifies the seed/starting value of an AutoNumber sequence

POLICY

How to control set_autonumber_seed

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_autonumber_seed": {
      "limits": [
        {
          "counter": "set_autonumber_seed_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set_autonumber_seed 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on set_autonumber_seed? +

Register the Dataverse MCP Server MCP server in PolicyLayer and add a rule for set_autonumber_seed: 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 Dataverse MCP Server. Nothing to install.

What risk level is set_autonumber_seed? +

set_autonumber_seed is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_autonumber_seed? +

How do I block set_autonumber_seed completely? +

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

set_autonumber_seed is provided by the Dataverse MCP Server MCP server (mwhesse/dataverse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Dataverse MCP Server tool call.

Start from Dataverse MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
