What mysql_spatial_create_index does on Mysql Mcp
AI agents use mysql_spatial_create_index to create or update resources in Mysql Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mysql Mcp environment.
Why mysql_spatial_create_index is rated Medium
Creating an index is a reversible write operation that modifies database structure but does not delete data or execute arbitrary code. It can be undone via DROP INDEX. Severity is medium because schema modifications can impact performance and require rollback capability, but the operation itself is not destructive or irreversible in practice.
From the tool's definition Tool name includes 'create' (index creation is a write operation). Description states 'Create a SPATIAL index' which modifies database schema/structure.
Attacks that exploit this kind of access
The rule that runs mysql_spatial_create_index safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_spatial_create_index, this is the rule to start with:
mysql_spatial_create_index 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Mysql Mcp, apply this rule, and every mysql_spatial_create_index call is checked against it from then on.
Questions about mysql_spatial_create_index
Create a SPATIAL index on a geometry column for faster queries. It is categorised as a Write tool in the Mysql Mcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mysql MCP server in PolicyLayer and add a rule for mysql_spatial_create_index: 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 Mysql Mcp. Nothing to install.
mysql_spatial_create_index 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 mysql_spatial_create_index 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 mysql_spatial_create_index. 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.
mysql_spatial_create_index is provided by the Mysql MCP server (oci:docker.io/writenotenow/mysql-mcp:v1.0.0). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
