## Summary Adds explicit MCP tool annotations for the Twenty MCP server so ChatGPT app submission review can inspect the exposed tools without relying on protocol defaults. ## Changes - Adds one-export annotation constants for closed-world read-only tools, open-world read-only tools, and `execute_tool`. - Attaches annotations to the five exposed MCP tools: `search_help_center`, `get_tool_catalog`, `learn_tools`, `execute_tool`, and `load_skills`. - Marks `search_help_center` as read-only and open-world because it performs outbound help-center HTTP requests. - Keeps `get_tool_catalog`, `learn_tools`, and `load_skills` read-only and closed-world. - Keeps `execute_tool` non-read-only, open-world, and destructive because it can route to tools that create/update/delete records or send email. - Returns annotations through `tools/list` and updates MCP tests to cover them. No output schemas are included in this PR. ## Validation - `git diff --check origin/main...HEAD` - `jest --config packages/twenty-server/jest.config.mjs packages/twenty-server/src/engine/api/mcp/services/__tests__/mcp-tool-executor.service.spec.ts packages/twenty-server/src/engine/api/mcp/services/__tests__/mcp-protocol.service.spec.ts --runInBand` Note: the Jest command was run with arm64 Node because the available shared `node_modules` install contains the arm64 SWC native binding.

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 deploy
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.
