Inbin: Email For AI Agents

@inbin/mcp

A minimal stdio-to-HTTP proxy for Inbin's Model Context Protocol surface. Lets stdio-only MCP clients (Claude Desktop, some Cursor builds, Zed, Cline) talk to Inbin's remote endpoint at https://api.inbin.dev/mcp.

Install & run

Nothing to install globally. Your MCP client invokes it via npx:

{
  "mcpServers": {
    "inbin": {
      "command": "npx",
      "args": ["-y", "@inbin/mcp"],
      "env": {
        "INBIN_API_KEY": "ink_live_..."
      }
    }
  }
}

Get an API key from https://inbin.dev/dashboard.

What it does

• Forwards each stdin JSON-RPC message to https://api.inbin.dev/mcp as an HTTPS POST with your Bearer key.
• Streams the response back to stdout.
• Notifications (messages with no id) get no reply, per JSON-RPC.
• Concurrent in-flight requests are supported.

Tools exposed

Every Inbin application is an MCP server. Available tools:

• list_inboxes — enumerate inboxes in your app
• list_events — filter by inbox / status / since; paginated
• search_events — substring search over id / subject / from / to
• get_event — a single event's parsed JSON + delivery history
• query_events — filter, sort, group and aggregate over extracted records (your inbox as a table)
• describe_schema — the current extraction schema

Environment

Remote (recommended)

If your MCP client supports Streamable HTTP transport, skip this wrapper entirely and connect directly:

{
  "mcpServers": {
    "inbin": {
      "url": "https://api.inbin.dev/mcp",
      "headers": {
        "Authorization": "Bearer ink_live_..."
      }
    }
  }
}
