Executes multiple SQL queries in parallel for improved performance.
AI agents invoke execute-batch-queries to trigger actions in MCP Firebird. 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.
This tool falls under Execute because it runs SQL queries whose effects depend entirely on the query arguments provided by the user/agent. While the tool itself is not inherently destructive, it has critical severity because: (1) parallel execution of multiple queries amplifies blast radius if an agent submits destructive queries (DELETE, DROP, ALTER); (2) there is no indication of input validation or query…
From the tool's definition Tool executes multiple SQL queries in parallel. The description explicitly states it 'Executes...SQL queries' and the tool name contains 'execute'.

Documented attack patterns abuse exactly the kind of access execute-batch-queries gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Firebird, and nothing reaches the server without passing your rules. This is the rule we recommend for execute-batch-queries:
{
"version": "1",
"default": "deny",
"tools": {
"execute-batch-queries": {
"limits": [
{
"counter": "execute-batch-queries_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}execute-batch-queries 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.
Free to start. No card required.
Executes multiple SQL queries in parallel for improved performance. It is categorised as a Execute tool in the MCP Firebird MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MCP Firebird MCP server in PolicyLayer and add a rule for execute-batch-queries: 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 MCP Firebird. Nothing to install.
execute-batch-queries is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the execute-batch-queries 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 execute-batch-queries. 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.
execute-batch-queries is provided by the MCP Firebird MCP server (purodelphi/mcpfirebird). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
