AI agents call list_stored_procedures 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) |
connectionName | string | — | Named connection to use (e.g., 'production', 'staging') |
connectionString | string | — | SQL Server connection string (uses default if not provided) |
includeSystemObjects | boolean | — | Include system stored procedures (default: false) |
Parameters from the server's own tool schema.
This tool retrieves metadata about stored procedures and functions without executing them, modifying data, or causing side effects. It is a pure read operation that returns schema information. The sibling tools (describe_*, analyze_*) reinforce that this server provides introspection capabilities.
From the tool's definition Tool name 'list_stored_procedures' and description 'List all stored procedures, functions, and their basic information' indicate a querying operation with no modification or execution of procedures.
Attacks that exploit this kind of access
List all stored procedures, functions, and their basic information. It is categorised as a Read tool in the Mssql MCP Server, which means it retrieves data without modifying state.
list_stored_procedures accepts 4 parameters: schema, connectionName, connectionString, includeSystemObjects. 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 list_stored_procedures: 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.
list_stored_procedures 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 list_stored_procedures 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 list_stored_procedures. 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.
list_stored_procedures 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.
