Resource Guru API and MCP server

Resource Guru's own AI connector is read-only, and its API needs an OAuth app you build and keep. Sign in to Resource Guru 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.

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

How do I connect Resource Guru 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. Resource Guru and every other app you connect show up as its tools.

  • ChatGPT
  • OpenClaw
  • Hermes
  • GrokBot
  • Cursor
  • n8n

    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/resource-guru with its own method and path, such as POST /api/v1/resource-guru/bookings, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the Resource Guru API and MCP server do?

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

Security overview

How much do the Resource Guru 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 Resource Guru is enabled for agents, so 20 calls a day come to 250 credits.

Questions

Does Resource Guru have an API?

Resource Guru has a public REST API with OAuth 2 that reads and writes bookings, projects, clients, resources and time off, and an official MCP server that only reads (checked 23 Oct 2026). The MCP server shows schedules, availability, utilization, project budgets and time off, and cannot change any of it. To act on the account, you register an app in the Developer Center and build the agent tools yourself.

How do I get access?

Sign up free, open Resource Guru 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 Resource Guru yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so Resource Guru 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_booking, create_total_hours_booking, update_booking, delete_booking, resolve_booking, add_time_off wait for your OK by default. You can switch that off per tool for scheduled runs.

Do I need a certain Resource Guru plan?

Bookings, Total Hours bookings and the official read-only MCP server are on all plans. The Approval Workflow, which resolve_booking needs, is part of the Master plan. Your own permissions count too: creating projects and clients needs Manager or higher.

Should I use a Resource Guru 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 Resource Guru 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 Resource Guru?

No. Cotlet is independent and not affiliated with Resource Guru.
