AgentKey

One MCP gateway and master key for live search, scrape, social, finance, and crypto data.

Open source

AgentKey is Chainbase's hosted MCP server and installer/plugin that routes agent requests across ~1,800 live-data tools (search, scrape, social, crypto, finance, business, e-commerce) behind one subscription and auto-failover. The open-source CLI/plugin configures supported coding agents; the MCP endpoint itself is managed at api.agentkey.app.

Selection advice

Choose AgentKey when the bottleneck is live external data access across many providers, not SaaS write-tool catalogs. Choose Composio when agents must authenticate into and mutate SaaS apps; choose Arcade.dev when you need a production MCP authorization runtime rather than a data marketplace.

Quick comparison

AgentKey concentrates on live external data through one MCP connection and credit plan. Composio focuses on SaaS action catalogs with managed OAuth; Arcade.dev focuses on authorized MCP tool runtimes.

Best for

  • live web/social/market data over MCP
  • one master key instead of many provider APIs
  • coding agents that need discover → describe → execute tool calls
  • auto-failover across upstream data providers

Not ideal for

  • teams that only need internal SaaS write actions (CRM/tickets)
  • fully air-gapped deployments that cannot call a hosted MCP endpoint
  • projects that already own and prefer to operate every data API directly

Minimal implementation shape

Run `curl -fsSL https://agentkey.app/install.sh | bash` (or the Windows install script), create an `ak_...` master key in the console, restart your agent, then ask it to `find_tools` for a live query and `execute_tool` on the returned Provider/Operation.
