Query and manage Mercoa AP/AR bill-pay: entities, invoices, transactions and payment methods.
The publisher's own server: Ably MCP by usefulapi
Query and manage Mercoa AP/AR bill-pay from an assistant: find entities, invoices, transactions and payment methods, and create or update invoices.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fmercoa/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Query and manage Mercoa AP/AR bill-pay — entities, invoices, transactions and payment methods — from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Mercoa API key.
Live endpoint: https://mercoa.usefulapi.io/mcp · Homepage: https://usefulapi.io/mercoa

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 Mercoa credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/mercoa/
On first connect you'll paste your Mercoa API key. It's validated, stored per-user, and scoped to you.
