Add a business insight or analysis note to the memo
AI agents use append_insight to create or update resources in DBeaver MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DBeaver MCP Server environment.
The action is reversible (insights/notes can be edited or removed) and has no side effects on core data integrity. It does not execute queries, delete data, or trigger external operations. This is a straightforward metadata write operation on a memo or annotation field, making it Write category with low severity due to limited blast radius.
From the tool's definition Tool name is 'append_insight' and description states 'Add a business insight or analysis note to the memo' — this creates or appends data to a memo/notes field without destructively modifying underlying database structures.
Documented attack patterns abuse exactly the kind of access append_insight gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DBeaver MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for append_insight:
{
"version": "1",
"default": "deny",
"tools": {
"append_insight": {
"limits": [
{
"counter": "append_insight_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}append_insight 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.

Add a business insight or analysis note to the memo. It is categorised as a Write tool in the DBeaver MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the DBeaver MCP Server MCP server in PolicyLayer and add a rule for append_insight: 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 DBeaver MCP Server. Nothing to install.
append_insight 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 append_insight 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 append_insight. 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.
append_insight is provided by the DBeaver MCP Server MCP server (srthkdev/omnisql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
