wmcp.sh vs Arcade.dev.

Arcade.dev is a managed tool-calling platform with polished OAuth UX for owner-side SaaS connectors. wmcp.sh covers the same ground PLUS shopper-side adapters, automatic OpenAPI ingest, and oracle/price-data. Closest direct comparison we have. Here's the honest version.

Arcade's OAuth flows for Gmail / Slack / GitHub are well-engineered. We aren't claiming to beat them at the curated-OAuth game — we're playing a broader game.

wmcp.sh is not affiliated with, endorsed by, or sponsored by Arcade AI, Inc. All claims about Arcade are based on their public documentation; pricing and feature details are subject to change — see arcade.dev for canonical info.

The shape difference

One sentence each.

Arcade.dev

A managed platform for AI agent tool calling — strong on per-customer OAuth UX for owner-side SaaS connectors (Gmail, Slack, GitHub, Linear, etc.) with curated, hand-tuned integrations and a hosted runtime.

wmcp.sh

A runtime MCP gateway: point it at any public URL, OpenAPI spec, or upstream MCP server. Shopper-side adapters (Shopify), automatic OpenAPI ingest (Stripe, GitHub), and an OAuth-proxy MCP server for OAuth-gated MCP upstreams.

When they win — honestly

Arcade is a real product. Here's where it's the right pick.

Arcade wins when:

  • Your end users need to authorize their own Gmail / Slack / GitHub / Linear and you want that flow to "just work" with zero plumbing
  • You want a curated catalog where each provider is hand-tuned and tested
  • You're shipping an owner-side AI product and OAuth polish is a top customer-perceived feature
  • You prefer a managed runtime over running your own gateway
  • You don't need shopper-side scraping, oracle data, or OpenAPI ingest of arbitrary specs

wmcp.sh wins when:

  • Your agent acts on systems your user doesn't own (Shopify shopper-side, DeFi data, public APIs without consumer accounts)
  • You want every endpoint in Stripe's or GitHub's OpenAPI spec exposed as MCP tools without per-endpoint curation
  • You need oracle / DeFi / price-data MCP adapters (CoinGecko, DefiLlama, Pyth, Chainlink, DexScreener)
  • You want a free 100/day anonymous tier with no signup
  • You want an MCP-native OAuth-proxy server so Claude.ai / Cursor users access OAuth-gated MCP upstreams without driving PKCE themselves
  • You want managed agent-readiness for YOUR own site (we ship JSON-LD + MCP server + verified badge)

FAQ

Common questions.
