Reduces output tokens for all 13 metadata tools by (~49%) based on
production sampling data.
GET tools (field + object metadata)
System fields are now returned as compact {id, name, type} instead of
the full ~20-key payload (opt-in includeFullSystemFields to get full
payload). System objects are similarly compacted to {id, nameSingular,
namePlural}.
Internal fields the agent never uses (searchVector, deletedAt, position,
updatedBy) are excluded entirely.
workspaceId and applicationId are hoisted into a response envelope
instead of being repeated on every record.
Null/default-false properties are stripped from custom field and object
payloads (e.g. options: null, settings: null, isUIReadOnly: false).
CUD tools (create/update/delete)
Create and update field tools now return {id, name, type, label} instead
of the full DTO.
Create and update object tools now return {id, nameSingular,
labelSingular} instead of the full DTO.
Delete tools return {id, success: true} instead of the full DTO of the
deleted entity.
Validation errors are grouped by message — e.g. 10 fields failing the
same check produce one line with all names instead of 10 identical
lines.
Learn schemas (all tools)
UUID pattern regex stripped from JSON schemas (keeps format: "uuid").
$schema and additionalProperties: false stripped from all generated
schemas.
All Zod .describe() annotations and tool descriptions shortened.
Skill & tool description updates:
All references to the removed list_object_metadata_items tool replaced
with get_object_metadata / get_field_metadata across skill instructions,
dashboard tools, view filter/sort tools, and MCP server instructions.

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
