Twenty: Open-Source CRM with TypeScript SDK and MCP Support

LinkTool

Twenty positions itself as an open-source alternative to proprietary CRMs like Salesforce and HubSpot. Aimed at technical teams, it pairs a Notion-like user interface with TypeScript developer tooling, no-code configuration, and native AI integration via the Model Context Protocol (MCP).

Key points

  1. Open-source foundation offering self-hosting for full infrastructure control or a managed cloud service.
  2. Customisations handled via no-code workspace settings or code using the TypeScript SDK (`npx create-twenty-app`).
  3. Extensibility covers custom objects, server-side logic functions, and React components rendered inside the CRM interface.
  4. Native Model Context Protocol (MCP) server built into Cloud workspaces, enabling direct natural-language read/write via Claude, ChatGPT, or Cursor over OAuth.
  5. Migration support from Salesforce and HubSpot via CSV import or an API designed for datasets exceeding 50,000 records.
  6. Cloud pricing structured at $9/user/month for Pro and $19/user/month for Organization, which adds SSO and row-level permissions.

Why it matters

Organisations often struggle between inflexible, expensive proprietary platforms and the maintenance burden of building custom in-house software. Twenty provides a production-grade middle ground, combining prebuilt CRM workflows with open software engineering practices and AI connectivity.

Analysis

Twenty's main differentiator is treating CRM configuration as software development. Features such as schema definitions in TypeScript, version-controllable apps, and local testing reduce reliance on proprietary ecosystems. The out-of-the-box MCP integration also aligns the platform with current agentic workflows, allowing external LLMs to interact with business records seamlessly.
