Creates a new column (field) in a Dataverse table with the specified data type and configuration. Supports various column types including text, numbers, dates, lookups, and choice lists. Use this to add new fields to store specific data in your tables. Requires a solution context to be set first.
AI agents use create_dataverse_column 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.
Creating a column is a Write operation: it modifies the database schema by adding new fields. While schema changes are somewhat impactful, column creation is reversible (columns can be deleted) and does not destroy data or execute arbitrary code.
From the tool's definition Tool description explicitly states 'Creates a new column (field) in Dataverse table' — a CREATE operation that adds new fields to tables. This is a reversible structural modification to the database schema.
Documented attack patterns abuse exactly the kind of access create_dataverse_column gives an agent:
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 create_dataverse_column:
{
"version": "1",
"default": "deny",
"tools": {
"create_dataverse_column": {
"limits": [
{
"counter": "create_dataverse_column_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_dataverse_column 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.

Creates a new column (field) in a Dataverse table with the specified data type and configuration. Supports various column types including text, numbers, dates, lookups, and choice lists. Use this to add new fields to store specific data in your tables. Requires a solution context to be set first. 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 create_dataverse_column: 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.
create_dataverse_column 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 create_dataverse_column 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 create_dataverse_column. 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.
create_dataverse_column 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.
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.
