Converts an existing text column to an AutoNumber column by adding an AutoNumberFormat. The column must be a String type with Text format and should be empty or contain compatible data.
AI agents use convert_to_autonumber to create or update resources in Dataverse MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Dataverse MCP Server environment.
This tool modifies column definitions in a Dataverse table schema. While the operation is technically reversible (the column could be converted back), it materially alters the data structure and constraints of a table, affecting how data is stored and validated. This goes beyond simple data value updates and constitutes schema modification.
From the tool's definition Converts an existing text column to an AutoNumber column by adding an AutoNumberFormat. This modifies the schema of a table by changing a column's type and format, which is a reversible but significant structural change to the data model.
Attacks that exploit this kind of access
Converts an existing text column to an AutoNumber column by adding an AutoNumberFormat. The column must be a String type with Text format and should be empty or contain compatible data. It is categorised as a Write tool in the Dataverse MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Dataverse MCP Server MCP server in PolicyLayer and add a rule for convert_to_autonumber: 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.
convert_to_autonumber is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the convert_to_autonumber 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.
Set action: deny in the PolicyLayer policy for convert_to_autonumber. 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.
convert_to_autonumber is provided by the Dataverse MCP Server MCP server (wizspdemo/dataverse-mcp2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
