Modern Treasury MCP by usefulapi

Query your Modern Treasury payment-ops and ledger data from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Modern Treasury API key.

Live endpoint: https://modern-treasury.usefulapi.io/mcp · Homepage: https://usefulapi.io/modern-treasury

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://modern-treasury.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http modern-treasury https://modern-treasury.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "modern-treasury": {
      "url": "https://modern-treasury.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Modern Treasury credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/modern-treasury/

On first connect you'll paste your Modern Treasury org ID + API key. It's validated, stored per-user, and scoped to you.
