Mycel MCP server

The Mycel MCP server gives an AI assistant the same reach a firm owner has in Mycel: what needs the owner today, the firm’s clients, starting client work, approving and sending it, and invoicing. It speaks the Model Context Protocol over Streamable HTTP, is listed in the official MCP Registry as com.mycelhq/mycel, and uses the owner’s API key. The tools are the operations of the Mycel API.

Connect from Claude Code

claude mcp add --transport http mycel https://app.mycelhq.com/api/mcp \
  --header "Authorization: Bearer $MYCEL_API_KEY"

Connect from any MCP client

{
  "mcpServers": {
    "mycel": {
      "url": "https://app.mycelhq.com/api/mcp",
      "headers": { "Authorization": "Bearer <owner API key>" }
    }
  }
}

Create the key in Mycel under Settings, MCP. Tools that reach a client, such as approve_and_send and send_invoice, should be confirmed with the owner before the assistant calls them. Questions: contact us.
