Simpro API and MCP server

Simpro's API covers quotes, jobs, schedules and customers, but it takes API credentials from an administrator, partner approval for apps, and code you write and host. Sign in to Simpro 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.

Simpro has no API for this. So we run one for you.

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

AI agents connect over MCP, scripts call the REST API. Both reach the same 12 tools with one API key.

For AI agents: MCP

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

  • ChatGPT
  • OpenClaw
  • Hermes
  • GrokBot
  • Cursor
  • n8n
  • Any MCP client

    Add Cotlet to your agent

    Claude Code
    claude mcp add --transport http cotlet \
  https://cotlet.dev/mcp/v1 \
  --header "Authorization: Bearer $COTLET_API_KEY"
    Cursor
    {
  "mcpServers": {
    "cotlet": {
      "url": "https://cotlet.dev/mcp/v1",
      "headers": {
        "Authorization": "Bearer ${COTLET_API_KEY}"
      }
    }
  }
}
    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/simpro with its own method and path, such as POST /api/v1/simpro/quotes/{quote_id}/to-job/convert, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the Simpro API and MCP server do?

12 tools on your own Simpro account. Agents call them as operations of the MCP tools simpro_read and simpro_write; scripts call each one at its own REST endpoint, with the same inputs and answers.

Security overview

How much do the Simpro API and MCP server cost?

One price for both: a tool call costs the same over MCP or REST. Free 7-day trial with 2,000 credits, no card needed. Then one-time credit packs, no subscription, valid 12 months. Most calls use 25 credits, and your Cloud Browser uses 50 credits a day while Simpro is enabled for agents, so 20 calls a day come to 550 credits.

60,000 $249 2,400 $4.15

Only successful calls use credits; failed calls and timeouts cost nothing. At a balance of 0 calls pause, never a surprise charge. Authenticate with the Authorization: Bearer header.

Questions

Does Simpro have an API?

Simpro has a full REST API with OAuth 2.0 for quotes, jobs, schedules, customers and catalogue items, but no official MCP server (checked 17 Oct 2026). Your administrator creates the API credentials in your build, partner apps need approval from Simpro, and all calls share a limit of 10 per second per build.

How do I get access?

Sign up free, open Simpro 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 12 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 Simpro yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so Simpro 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: create_quote, convert_quote_to_job, update_job_status, add_schedule_entry wait for your OK by default. You can switch that off per tool for scheduled runs.

Does the Simpro rate limit apply to my agent?

Simpro limits its API to 10 calls per second per build and answers HTTP 429 above it (Simpro API forum, 2025). Cotlet works through your signed-in session, not through the API application.

Should I use a Simpro 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 Simpro 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 Simpro?

No. Cotlet is independent and not affiliated with Simpro.
