Dext API and MCP server

Dext has no API to list, edit, publish or export items. Sign in to Dext once in your own Cloud Browser, and your AI agent does the work there for you. The same tools work over MCP for agents and as a REST API for scripts.

How do I connect Dext to Claude, ChatGPT or my code?

AI agents connect over MCP, scripts call the REST API. Both reach the same 10 tools with one API key.

For AI agents: MCP

Add Cotlet to your agent once. Dext and every other app you connect show up as its tools.

    Add Cotlet to your agent

    Claude Code
    claude mcp add --transport http cotlet \

  --header "Authorization: Bearer $COTLET_API_KEY"
    Cursor

    Codex
    # ~/.codex/config.toml
[mcp_servers.cotlet]
url = "https://cotlet.dev/mcp/v1"
bearer_token_env_var = "COTLET_API_KEY"

    Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.

For scripts: REST API

Every tool is an endpoint under /api/v1/dext with its own method and path, such as POST /api/v1/dext/items/publish, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the Dext API and MCP server do?

10 tools on your own Dext account. Agents call them as operations of the MCP tools dext_read and dext_write; scripts call each one at its own REST endpoint, with the same inputs and answers.

Most calls use 25 credits, and your Cloud Browser uses 50 credits a day while Dext is enabled for agents, so 20 calls a day come to 550 credits.

Questions

Does Dext have an API?

Dext has no public developer API and no API docs on dext.com, and no official MCP server (checked 14 Oct 2026). The only official connection is the Zapier app, with 3 triggers and 4 actions: it submits receipts and sales invoices, reads processed receipts and creates client accounts.

How do I get access?

Sign up free, open Dext under Integrations in the console and press Request access. Your free trial starts with your account, no card needed.

Is the MCP server different from the API?

No, only the way in. Cotlet builds each integration as a REST API and puts an MCP server on top, so both have the same 10 tools, the same inputs and answers, one API key and one price. AI agents such as Claude, ChatGPT or Cursor use MCP; scripts, cron jobs and HTTP steps in n8n, Make or Zapier use the REST API.

What is the Cloud Browser?

Your own Chrome that Cotlet runs for you in the EU, around the clock. You open it from the console, sign in to Dext yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so Dext sees the browser you signed in with. Password saving is off and the profile is stored encrypted with AES-256-GCM.

Can my agent act without asking me?

Not on anything that reaches other people: publish_items, unarchive_items wait for your OK by default. You can switch that off per tool for scheduled runs.

Do I need a special Dext plan or role to publish?

Publishing needs the Admin role, or a publishing permission from an administrator. Cotlet works in your own Dext account, so it can do what that user can.

Can my agent publish items twice by mistake?

No by default. publish_items skips items that are not Ready and does not retry failures. Dext itself warns that unarchiving with cleared publishing data may create a duplicate in the accounting software, so unarchive_items asks for your OK.

Should I use a Dext MCP server from GitHub instead?

Pick one if you want the code on your own computer and do not mind the upkeep: you install it, sign it in and fix it when Dext changes. Pick Cotlet if you want it hosted and kept working for you.

Can I use it in n8n, Make or Zapier?

Yes. Add https://cotlet.dev/mcp/v1 in n8n's MCP Client node, or call the REST endpoints from an HTTP step in Make or Zapier.

Who runs Cotlet?

Cotlet is run by Take Group, a Polish software company working since 2019. Take Group runs about 3,200 websites on its own systems and has its own DevOps team for infrastructure security. We built and used integrations like this inside the company for years before opening them as Cotlet.

Is Cotlet affiliated with Dext?

No. Cotlet is independent and not affiliated with Dext.
