Execute a raw SurrealQL query against the connected database.
AI agents invoke query to trigger actions in SurrealDB MCP Server. 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.
Executing raw SurrealQL queries means an AI agent can run any arbitrary statement including destructive operations (DELETE, REMOVE TABLE), schema changes (DEFINE/REMOVE), and data exfiltration.
From the tool's definition "Execute a raw SurrealQL query against the connected database" — allows arbitrary raw query execution including DDL (DROP, DELETE, DEFINE, REMOVE) and DML operations
Documented attack patterns abuse exactly the kind of access query gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SurrealDB MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for query:
{
"version": "1",
"default": "deny",
"tools": {
"query": {
"limits": [
{
"counter": "query_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}query 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.

Execute a raw SurrealQL query against the connected database. It is categorised as a Execute tool in the SurrealDB MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the SurrealDB MCP Server MCP server in PolicyLayer and add a rule for query: 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 SurrealDB MCP Server. Nothing to install.
query 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 query 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 query. 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.
query is provided by the SurrealDB MCP Server MCP server (nsxdavid/surrealdb-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
