mcp_execute_procedure · Mcpql MCP: Risk & Policy

WHAT IT DOES

What mcp_execute_procedure does on Mcpql

AI agents invoke mcp_execute_procedure to trigger actions in Mcpql. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why mcp_execute_procedure needs a policy

Stored procedures are executable code units that can contain any SQL logic, including modifications to data, execution of extended stored procedures, or triggering of external operations. While the tool itself doesn't inherently delete data (which would be Destructive), it enables execution of arbitrary stored procedure logic whose effects depend on what the procedure contains.

From the tool's definition Tool name contains 'execute' and description states 'Execute a SQL Server stored procedure with parameters and return results'.

Verdict

mcp_execute_procedure Rate-limited

mcp_execute_procedure stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about mcp_execute_procedure

What does the mcp_execute_procedure tool do? +

Execute a SQL Server stored procedure with parameters and return results. It is categorised as a Execute tool in the Mcpql MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on mcp_execute_procedure? +

Register the Mcpql MCP server in PolicyLayer and add a rule for mcp_execute_procedure: 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 Mcpql. Nothing to install.

What risk level is mcp_execute_procedure? +

mcp_execute_procedure is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit mcp_execute_procedure? +

Yes. Add a rate_limit block to the mcp_execute_procedure 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.

How do I block mcp_execute_procedure completely? +

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

mcp_execute_procedure is provided by the Mcpql MCP server (mcpql). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
