AI agents call analyze_data_distribution to retrieve information from Mssql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
schema | string | — | Schema name (default: dbo) |
tableName | string | Yes | Name of the table to analyze |
columnName | string | — | Specific column to analyze (analyzes all if not provided) |
sampleSize | number | — | Sample size for analysis (default: 1000) |
connectionName | string | — | Named connection to use (e.g., 'production', 'staging') |
connectionString | string | — | SQL Server connection string (uses default if not provided) |
Parameters from the server's own tool schema.
This tool queries database statistics and column distributions to provide insights into data patterns. It is a read-only operation that retrieves analytical information without creating, modifying, deleting, or executing arbitrary code. The sibling tools like 'describe_*' and 'analyze_*' confirm this server exposes primarily informational and schema exploration capabilities.
From the tool's definition Tool name 'analyze_data_distribution' and description 'Get data distribution patterns for columns to understand data quality and patterns' indicate a retrieval and analysis operation with no modification or deletion of data.
Attacks that exploit this kind of access
Get data distribution patterns for columns to understand data quality and patterns. It is categorised as a Read tool in the Mssql MCP Server, which means it retrieves data without modifying state.
analyze_data_distribution accepts 6 parameters: schema, tableName, columnName, sampleSize, connectionName, connectionString. Required: tableName. The full parameter table on this page comes from the server's own tool schema.
Register the Mssql MCP server in PolicyLayer and add a rule for analyze_data_distribution: 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 Mssql. Nothing to install.
analyze_data_distribution is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the analyze_data_distribution 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 analyze_data_distribution. 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.
analyze_data_distribution is provided by the Mssql MCP server (mssql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
