Low Risk

select

Select all records from a table or a specific record by ID.

How to control select ↓

AI agents call select to retrieve information from SurrealDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

The select tool only reads/queries data from SurrealDB tables or specific records. It performs no modifications, deletions, or executions. Misuse risk is low, limited to potential data exposure.

From the tool's definition "Select all records from a table or a specific record by ID" — pure retrieval, no side effects

Documented attack patterns abuse exactly the kind of access select 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 select:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "select": {}
  }
}

select is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register SurrealDB MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the select tool do? +

Select all records from a table or a specific record by ID. It is categorised as a Read tool in the SurrealDB MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on select? +

Register the SurrealDB MCP Server MCP server in PolicyLayer and add a rule for 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 SurrealDB MCP Server. Nothing to install.

What risk level is select? +

select is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit select? +

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

Set action: deny in the PolicyLayer policy for 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 select? +

select 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.

Enforce policy on every SurrealDB MCP Server tool call.
