AI agents use createManyViewFilters to create or update resources in Twenty MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Twenty MCP Server environment.
This tool creates viewFilters, which are configuration objects that define how data is displayed in a CRM interface. Creation of filters is a write operation—data is being added to the system but can be modified or deleted later.
From the tool's definition Tool name is 'createManyViewFilters' with description 'Create Many viewFilters'. The verb 'create' and bulk action pattern 'createMany' indicates reversible data creation.

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