Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package zapier-discovery-mcp
Claude Code 
claude mcp add zapier-discovery-mcp -e 'ZAPIER_CLIENT_ID=<ZAPIER_CLIENT_ID>' -- npx -y zapier-discovery-mcp@0.1.0

            "command": "npx",
            "args": [
                "-y",

zapier-discovery-mcp

An MCP server for automation discovery. Zapier MCP executes automations — this server answers the question that comes first: what could I automate?

  • "What do people automate between Slack and Notion?" — real, popular Zap templates, each with a one-click create link
  • "Is there a Zapier integration for this tool?" — search the 9,000+ app directory
  • "Give me automation ideas for my CRM" — templates ranked by actual usage, not hallucinated

Sibling project: zapier-dev-mcp for building Zapier integrations.

Setup

You need a Zapier Partner API client_id — free with any Zapier integration, and not a secret (it ships in client-side embed code). See the Partner API docs for where to find yours.

Claude Code

claude mcp add zapier-discovery --env ZAPIER_CLIENT_ID=your_client_id -- npx -y zapier-discovery-mcp

Claude Desktop — add to claude_desktop_config.json:

{
  "mcpServers": {
    "zapier-discovery": {
      "command": "npx",
      "args": ["-y", "zapier-discovery-mcp"],
      "env": { "ZAPIER_CLIENT_ID": "your_client_id" }
    }
  }
}

Optional: ZAPIER_API_BASE overrides the API host (testing, proxies).

Tools

ToolWhat it does
search_appsSearch the app directory by name; popularity-ordered without a query. Returns slugs for the next step.
find_zap_templatesPopular ready-made Zap templates for one app or a pair — title, step chain (Slack → Notion), description, one-click create URL

Design notes

  • Defensive parsing. Partner API responses are only partially documented; the client whitelists fields and handles both bare-array and enveloped responses rather than assuming shapes.
  • Testable without credentials. The smoke test runs a local HTTP mock of the Partner API and points the server at it via ZAPIER_API_BASE — full end-to-end over stdio with zero secrets. Missing ZAPIER_CLIENT_ID produces setup instructions as a tool error, not a crash.
  • HTML in titles/descriptions is stripped and truncated before it reaches the model.

Development

npm install
npm test                 # offline unit tests (mocked fetch)
npm run build            # tsc → dist/
node scripts/smoke.mjs   # end-to-end against a local Partner API mock
