ResMan API and MCP server

ResMan's API is only for approved Integration Partners, so a property manager cannot read work orders, leases or ledgers from code. Sign in to ResMan 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.

ResMan's own API leaves this out. So we run one for you.

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

AI agents connect over MCP, scripts call the REST API. Both reach the same 13 tools with one API key.

For AI agents: MCP

Add Cotlet to your agent once. ResMan 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": {

      "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/resman with its own method and path, such as POST /api/v1/resman/properties/{property_id}/work-orders, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the ResMan API and MCP server do?

13 tools on your own ResMan account. Agents call them as operations of the MCP tools resman_read and resman_write; scripts call each one at its own REST endpoint, with the same inputs and answers.

Security overview

How much do the ResMan 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. Each call uses 10 credits, and your Cloud Browser uses 50 credits a day while ResMan is enabled for agents, so 20 calls a day come to 250 credits.

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 ResMan have an API?

ResMan has an API, but only for approved Integration Partners (checked 23 Oct 2026). A property manager cannot get a key for their own account, and ResMan has no official MCP server. Partners get JSON endpoints for work orders, units, leases, prospects and ledgers.

How do I get access?

Sign up free, open ResMan 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 13 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 ResMan yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so ResMan 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_work_order, update_work_order wait for your OK by default. You can switch that off per tool for scheduled runs.

Can my agent post charges, take payments or pay invoices in ResMan?

No. The ResMan tools read ledgers, receivables, leases and prospects, and write only work orders. Posting charges, taking payments and paying invoices stay in ResMan, even though the Partner API documents an invoice payment method.

Which work order statuses can my agent set?

update_work_order sets Submitted, Not Started, In Progress, Completed, Scheduled, Cancelled, Closed or On Hold, the statuses ResMan documents for work orders. A resident who reported the work order can see the new status in the Resident Portal, so each update asks for your OK by default.

Should I use a ResMan 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 ResMan 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 ResMan?

No. Cotlet is independent and not affiliated with ResMan.
