Hyros MCP

Hyros MCP Server

 

Connect Hyros advertising attribution to AI assistants (Claude, Cursor, etc.) through the Model Context Protocol. Ask questions about your leads, sales, calls, subscriptions, and ad performance — and let the AI pull the data and run the reports for you.

53 tools covering leads, sales, calls, subscriptions, products, custom costs, carts, webhooks, attribution reports, ad management, and smart analytics. Targets Hyros REST API v1.39 and Webhooks v1.1.

Built by Carlos Aragon.

🚀 Install in 60 seconds (recommended — no downloads, no setup)

You only need the Claude app (desktop or web). Nothing to install. No terminal. No Node.js. No config files.

1. Open Claude → Settings → Connectors.
2. Click Add custom connector.
3. Paste this address and click Add:

   https://hyrosmcp.callwithcarlos.com/mcp

1. A small page opens in your browser asking for your Hyros API key.

Get it from Hyros → Settings → Integrations → API, paste it, and click Connect.

1. Done ✅ — Hyros now shows up in Claude's tools. Try asking "What was my revenue today?"

That's the whole thing. Your key is checked the moment you paste it (so you know right away if it's wrong) and is stored encrypted on the server — it never lives on your computer, and you never edit any files.

Controlling what the AI can do (permissions)

Inside Claude, every tool can be set to:

• Always allow — runs without asking (great for read-only reports and lookups)
• Ask every time — Claude asks for your approval before each use
• Blocked — never runs

You'll find these in the connector's settings in Claude. The tools that change data (create a lead, refund an order, etc.) are flagged so Claude asks first by default.

If a tool answers "Unauthorized"

Hyros API keys carry roles, and several endpoints need a role that is not on a key by default. When a key lacks the role the API replies 401 Unauthorized with no explanation of which role is missing, so the tool looks broken when the key is simply too narrow.

Verified against Hyros API v1.39 on 2026-08-04, these tools need extra roles:

| Tools | Needs a role for | |---|---| | hyros_get_products, hyros_update_product, hyros_delete_product | Products | | hyros_get_custom_costs, hyros_update_custom_cost, hyros_delete_custom_cost | Custom costs | | hyros_get_carts | Carts | | hyros_get_webhook_subscriptions, hyros_create_webhook_subscription, hyros_delete_webhook_subscription | Webhooks | | hyros_update_source, hyros_delete_source | Sources (write) | | hyros_delete_lead | Leads (delete) |

Fix it in the Hyros app under Settings → API Keys by enabling the roles on your key, or issue a key with full roles. A wrong key reads differently: it returns a JSON body containing Api key not valid, while a missing role returns the bare text Unauthorized.

Agency-level keys are a separate limit. They authenticate on hyros_get_user_info but return 401 on every data endpoint, and the API has no way to scope a request to a client account. Use a key from the client account itself.

How it works (the short version)

You (Claude app)  ──▶  hyrosmcp.callwithcarlos.com  ──▶  Hyros API
                       (a secure hosted server)

There's a small server running in the cloud (on Cloudflare) that speaks to Hyros on your behalf. When you connect, it asks for your API key once, verifies it, and keeps it encrypted. From then on, when you ask Claude a question, Claude talks to that server, which fetches your real Hyros data and hands it back. You don't host or maintain anything.

For developers / self-hosters: the server lives in worker/ and runs on Cloudflare Workers. See DEPLOY.md to deploy your own copy.

Alternative — Run it locally (advanced / developers)

Prefer to run the server on your own machine instead of using the hosted one? This uses the npm package and Claude Desktop's local config. You'll need Node.js 18+.

Step 1 — Install the package

Open a terminal and run:

npm install -g hyros-mcp

This works on Windows, macOS, and Linux.

Step 2 — Add to Claude Desktop

Open your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this (replace your_api_key_here with your key from Hyros → Settings → Integrations → API):

{
  "mcpServers": {
    "hyros": {
      "command": "hyros-mcp",
      "args": [],
      "env": {
        "HYROS_API_KEY": "your_api_key_here"
      }
    }
  }
}

Step 3 — Restart Claude Desktop

Close and reopen Claude Desktop. That's it — you're ready to use it.

---

Claude Code (CLI)

npm install -g hyros-mcp
claude mcp add hyros -e HYROS_API_KEY=your_api_key_here -- hyros-mcp

Cursor / Windsurf

Same config as Claude Desktop above — add it to your MCP settings file.

Troubleshooting

Remote connector (the 60-second install)

"That key didn't work" when you paste it — The key is wrong, expired, or lacks permissions. Copy it again, exactly, from Hyros → Settings → Integrations → API. The page tells you immediately if it's valid.

Hyros tools don't appear in Claude — Make sure you finished the browser step (pasting the key and clicking Connect). Re-open Settings → Connectors and confirm Hyros is listed and connected.

Need to change your API key later — Just disconnect and re-add the connector (or reconnect) and paste the new key. Nothing else to update.

Local install

"401 Unauthorized" — Your API key is wrong, missing, or lacks the role the endpoint needs. Make sure:

1. HYROS_API_KEY is inside the env block
2. The key is copied exactly from Hyros → Settings → Integrations → API
3. You restarted Claude Desktop after saving the config
4. The key has the role that tool needs, if only some tools fail — see

If a tool answers "Unauthorized"

MCP tools not showing up — Restart Claude Desktop. The config is only read at startup.

"command not found: hyros-mcp" — The global install didn't complete. Run npm install -g hyros-mcp again and make sure npm's global bin folder is in your PATH.

• "Create a lead with email test@example.com and tag them as VIP"
• "Which leads were updated since yesterday?"
• "Show me carts abandoned in the last week"
• "Remove the trial tag from john@example.com"
• "Which custom costs are still running with no end date?"

Security

• HTTPS-only connections (API key never sent over plaintext)
• Domain-restricted to *.hyros.com (prevents SSRF)
• Runtime input validation on all tool parameters
• Request timeouts (30s) with retry logic
• Client-side rate limiting (25 req/sec)
• Path traversal prevention on URL parameters

Development

git clone https://github.com/CachoMX/Hyros-MCP.git
cd Hyros-MCP
npm install
cp .env.example .env    # Add your API key
npm run build           # Compile TypeScript (local/stdio version)
npm run dev             # Run in development mode
npm test                # Run tests

Remote server (Cloudflare Worker)

The hosted connector lives in worker/ and reuses all the tool logic in src/. It adds a Streamable HTTP transport plus an OAuth layer that collects each user's Hyros API key on a single-field page.

npm run worker:check    # Validate the bundle (wrangler dry-run, no deploy)
npm run worker:dev      # Local dev server (wrangler dev)
npm run worker:deploy   # Deploy to Cloudflare

Full operator instructions — Cloudflare token scopes, KV setup, custom domain — are in DEPLOY.md.
