WHAT IT DOES

What db_select does on EasyBits

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

RISK

Why db_select is rated Medium

An AI agent can call db_select faster than any human can review: one bad instruction and it creates or modifies resources in EasyBits by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs db_select safely

PolicyLayer is an MCP gateway: it sits between your AI agents and EasyBits, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For db_select, this is the rule to start with:

db_select Rate-limited

db_select 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 EasyBits, apply this rule, and every db_select call is checked against it from then on.

FAQ

Questions about db_select

What does the db_select tool do? +

Read-only counterpart of db_query — accepts only a single SELECT statement. Rejects anything that mutates, escalates, or stacks queries.

It is categorised as a Write tool in the EasyBits MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on db_select? +

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

What risk level is db_select? +

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

Can I rate-limit db_select? +

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

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

db_select is provided by the EasyBits MCP server (@easybits.cloud/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
