AI agents use batch_update_bitable_records to create or update resources in Personal Knowledge MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Personal Knowledge MCP Server environment.
This tool modifies existing records in a Feishu bitable (multi-dimensional table) without deleting them. Updates are reversible, placing it in the Write category. Severity is medium because batch operations on enterprise knowledge base records could affect multiple documents or records, but the changes are not permanent or destructive.

PolicyLayer is an MCP gateway — it sits between your AI agents and Personal Knowledge MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for batch_update_bitable_records:
{
"version": "1",
"default": "deny",
"tools": {
"batch_update_bitable_records": {
"limits": [
{
"counter": "batch_update_bitable_records_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}batch_update_bitable_records 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.
