Zapier AI Actions exposes Zapier's 7,000+ integrations as tools AI agents can call. Zapier offers a hosted MCP server front-end so any MCP-speaking agent can reach Gmail, Slack, HubSpot, and more.

Zapier AI Actions + Foldr FAQ
How do I install the Foldr MCP server in Zapier AI Actions?
Open Zapier AI Actions's MCP configuration (Settings → Connectors / Integrations) and paste the config block shown above. Set FOLDR_API_KEY to a key you create at foldr.space/developers/signup. Restart Zapier AI Actions if it doesn't hot-reload.
How much does it cost to use Foldr from Zapier AI Actions?
Each upload costs 5¢. You can pay by topping up account credits via the `top_up_credits` MCP tool (min $5) - every upload then debits from balance. Or subscribe to Pro tier ($25/mo) and per-call charges are bypassed entirely. Tools that don't write data (list_files, mint_capability, get_usage, etc.) are free.
I set the key but Zapier AI Actions says the Foldr tool isn't available - what's wrong?
Three common causes: (1) Zapier AI Actions wasn't restarted after editing the config - most MCP hosts need a restart to pick up new servers. (2) The API key is wrong or missing - verify the env var name your client reads (e.g. FOLDR_API_KEY) matches the config snippet above. (3) Your client doesn't support the streamable-http transport - most modern clients do, but check Zapier AI Actions's docs for the version that added MCP support.
Can Zapier AI Actions upload files directly to Foldr, or just generate URLs?
Zapier AI Actions can do both. The MCP server exposes tools for `upload_file` (base64-encoded file content), `bulk_upload` (up to 20 files in one call), `mint_capability` (short-lived shareable links), and `create_short_url`. Any file Zapier AI Actions can read from disk can be uploaded.
Is the Foldr MCP integration with Zapier AI Actions production-ready?
Foldr's MCP server is stable and used in production - streamable-http transport at https://foldr.space/api/mcp with 23 tools. Zapier AI Actions's MCP support is currently in public beta - suitable for day-to-day use. Every write endpoint accepts an Idempotency-Key so retries are safe.
