Perplexity

Manage your client database directly

Stop switching windows to check client details. You can use `list_clients` to pull your full directory into the chat and `get_client` to verify specific contact information without leaving the desktop app. Adding new accounts is just as fast. Simply tell your agent to run `create_client` with the required parameters to push your new lead directly into your billing system.

Generate invoices from your chat

You no longer need to copy-paste line items manually. Use `create_invoice` to generate a new billing record based on your project requirements and let the agent handle the data entry. If you need to review existing records, `list_invoices` gives you the status of pending payments. It's the fastest way to keep your books updated while you focus on writing code.

Sync your product catalog

Keep your service pricing consistent by pulling data directly from your account. The `list_products` tool displays your current offerings, while `get_product` provides the specific pricing details you need for a quote. Use `create_product` whenever you add a new service to your lineup. This keeps your billing information accurate and accessible without opening a web dashboard.

Common questions about Invoice Ninja MCP in Claude Desktop

Open your configuration file at the path provided in the Claude settings. Add the server under the mcpServers key, define your command, and restart the application to enable the tools.

The server only accesses the specific client and payment records you request via tool calls. Your data remains encrypted in transit and is never shared with other users or training models.

Yes, as long as you have the latest version of the app installed. Ensure your config file includes the correct path to your node environment so the MCP server can execute properly.

This means you hit an API rate limit. Wait a few moments before asking your agent to retry the command, or check your account usage for any ongoing background syncs.

You provide an endpoint token during the initial setup. The server uses this token to authenticate your requests securely against the API for every transaction.
