Kanto Labs MCP Server

Kanto Labs MCP server

An MCP server that gives AI assistants (Claude, Cursor, VS Code Copilot and any other MCP client) 14 web, data and media tools, backed by Kanto Labs' actors on the Apify Store:

Failed or unreachable inputs are not charged.

Coming soon: enrich_company, upscale_image, get_topic_trends, get_trending_topics, check_website_traffic_rank, search_free_images are listed already, but their actors are not yet public on the Apify Store; until they are, calls to them return an "actor not yet public" error (nothing is charged).

How billing works

The server is free and open source (MIT). Each tool call runs the matching actor on Apify with your own Apify API token, so the actor's pay-per-event price is billed to your Apify account (Apify's free plan includes monthly credit). There is no Kanto Labs account, key or subscription.

Every call carries a spending cap: maxTotalChargeUsd (default $1.00, change it with the KANTO_MAX_CHARGE_USD env var or per call). Apify stops the run once it has charged that much, so an assistant cannot run up a large bill by accident. Each result states what the call cost.

Setup

1. Get an Apify API token: sign up at apify.com, then Settings -> API & Integrations (console.apify.com/settings/integrations).
2. Add the server to your client (Node.js 18.17+ required; npx downloads and builds it from GitHub on first run).

Claude Desktop

Edit claude_desktop_config.json (Settings -> Developer -> Edit Config):

{
  "mcpServers": {
    "kanto-labs": {
      "command": "npx",
      "args": ["-y", "github:kanto-labs/kanto-labs-mcp"],
      "env": { "APIFY_TOKEN": "apify_api_your_token_here" }
    }
  }
}

Or install the one-click bundle kanto-labs-mcp.mcpb from the Releases page: double-click it and paste your token when asked.

Claude Code

claude mcp add kanto-labs -e APIFY_TOKEN=apify_api_your_token_here -- npx -y github:kanto-labs/kanto-labs-mcp

Cursor

~/.cursor/mcp.json (global) or .cursor/mcp.json (project):

{
  "mcpServers": {
    "kanto-labs": {
      "command": "npx",
      "args": ["-y", "github:kanto-labs/kanto-labs-mcp"],
      "env": { "APIFY_TOKEN": "apify_api_your_token_here" }
    }
  }
}

VS Code (GitHub Copilot agent mode)

.vscode/mcp.json - the token is asked for once and stored securely:

{
  "inputs": [
    { "type": "promptString", "id": "apify_token", "description": "Apify API token", "password": true }
  ],
  "servers": {
    "kanto-labs": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "github:kanto-labs/kanto-labs-mcp"],
      "env": { "APIFY_TOKEN": "${input:apify_token}" }
    }
  }
}

Windsurf, Cline, Zed and others

Any client that launches stdio servers works: command npx, args -y github:kanto-labs/kanto-labs-mcp, env APIFY_TOKEN.

Windows: if your client reports spawn npx ENOENT, use "command": "cmd" with "args": ["/c", "npx", "-y", "github:kanto-labs/kanto-labs-mcp"].

Environment variables

Adding actors

Tools are generated from actors.config.json: the Apify actor ID, the tool description, typed parameters, price (with optional per-result price rules and a per-result charge count for actors that bill several events per row), input defaults, and a one-line summary template. Adding an actor is a config entry, no code. comingSoon: true marks an actor that is not public on the Apify Store yet (the tool is listed with a notice and a 404 is explained); fixedInput pins actor input for a tool (one actor can back several tools). npm run build regenerates the tool table above and manifest.json from the config.

Development

npm install
npm run build
npm test                                   # offline: lists tools, checks the missing-token error
APIFY_TOKEN=... npm run test:live          # one tiny real call per tool (about $0.04)
npx @modelcontextprotocol/inspector node dist/index.js   # interactive inspector
npm run bundle                             # builds build/kanto-labs-mcp.mcpb
