Add a new table to an existing code search group, expanding what gets searched.
AI agents use add_code_search_table to create or update resources in Now Sdk Ext — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Now Sdk Ext environment.
This tool creates or modifies configuration data (adding a table to a search group) without destroying data or executing arbitrary code. While it could have broader system impacts if misused (expanding search scope unexpectedly), it remains a Write operation as it is reversible—the table can be removed from the group.
From the tool's definition The tool "Add a new table to an existing code search group" performs a create/add operation that modifies the configuration of a code search group by expanding its scope. This is a reversible modification of system data.
Documented attack patterns abuse exactly the kind of access add_code_search_table gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Now Sdk Ext, and nothing reaches the server without passing your rules. This is the rule we recommend for add_code_search_table:
{
"version": "1",
"default": "deny",
"tools": {
"add_code_search_table": {
"limits": [
{
"counter": "add_code_search_table_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_code_search_table 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 new table to an existing code search group, expanding what gets searched. It is categorised as a Write tool in the Now Sdk Ext MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Now Sdk Ext MCP server in PolicyLayer and add a rule for add_code_search_table: 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 Now Sdk Ext. Nothing to install.
add_code_search_table 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 add_code_search_table 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 add_code_search_table. 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.
add_code_search_table is provided by the Now Sdk Ext MCP server (sonisoft-cnanda/now-sdk-ext-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Now Sdk Ext, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
