Use Foldr with Poe (MCP)

Poe is Quora's multi-model chat app (Claude, GPT-4, Gemini, DALL·E, and dozens of third-party bots) with strong iOS and Android clients. Poe bots built with the Server Bot API can proxy to MCP servers. Foldr can back a Poe "upload" bot, making shared file URLs available inside Poe conversations.

QuoraiOS, Android, WebMCP: community

Installation

Add the Foldr MCP server to Poe with the snippet below. Replace fs_… with an API key from foldr.space/developers/signup. Each upload costs 5¢ - top up account credits or subscribe to Pro tier to bypass per-call charges.

// Poe Server Bot (Python) - proxies to Foldr MCP
from fastapi_poe import PoeBot, Tool
from mcp_client import connect

foldr = connect("https://foldr.space/api/mcp", token="fs_live_...")

class FoldrBot(PoeBot):
    async def get_response(self, req):
        return await foldr.forward(req)

Setup tip: Register the bot at poe.com/create-bot → Server bot. Mobile users then add it from the Poe app.

Poe + Foldr FAQ

How do I install the Foldr MCP server in Poe?

Open Poe's MCP configuration (the Integrations panel) and paste the config block shown above. Set FOLDR_API_KEY to a key you create at foldr.space/developers/signup. Restart Poe if it doesn't hot-reload.

How much does it cost to use Foldr from Poe?

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 Poe says the Foldr tool isn't available - what's wrong?

Three common causes: (1) Poe 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 Poe's docs for the version that added MCP support.

Can Poe upload files directly to Foldr, or just generate URLs?

Poe 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`. On mobile, uploads use the device camera roll / share sheet via the remote MCP endpoint.

Is the Foldr MCP integration with Poe production-ready?

Foldr's MCP server is stable and used in production - streamable-http transport at https://foldr.space/api/mcp with 23 tools. Poe's MCP support is currently community-maintained - check the upstream repo for current status. Every write endpoint accepts an Idempotency-Key so retries are safe.
