rollback_sp · MSSQL MCP Server MCP: Risk & Policy

WHAT IT DOES

What rollback_sp does on MSSQL MCP Server

AI agents use rollback_sp to create or update resources in MSSQL MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MSSQL MCP Server environment.

WHY IT NEEDS A POLICY

Why rollback_sp needs a policy

Rolling back a stored procedure overwrites the current version with a previous one, which is a reversible write operation (the current version is replaced but prior versions presumably exist). However, the blast radius is high because overwriting a stored procedure in production could affect all callers and disrupt database operations.

From the tool's definition Rollback a stored procedure to a previous version. Can specify version number or use latest backup.

Verdict

rollback_sp Rate-limited

rollback_sp 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.

Rollback a stored procedure to a previous version. Can specify version number or use latest backup. It is categorised as a Write tool in the MSSQL MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on rollback_sp? +

What risk level is rollback_sp? +

rollback_sp is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit rollback_sp? +

Yes. Add a rate_limit block to the rollback_sp 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 rollback_sp completely? +

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

rollback_sp is provided by the MSSQL MCP Server MCP server (jpcanter/sql-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
