create_invoice — Create invoice
Advertised by the server during the last successful anonymous check.
Advertised read-only

Build a complete invoice as structured data: invoice number, issue and due dates, line items, discount, tax, total and payment terms. Nothing is stored. Use when the user wants an invoice for a client. Do NOT use for totals only (use calculate_totals) or for a printable text version (use render_invoice_text).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http invoicegen-mcp https://invoice-gen.magicteams.ai/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add invoicegen-mcp --url https://invoice-gen.magicteams.ai/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable invoicegen-mcp in your MCP settings.

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http invoicegen-mcp https://invoice-gen.magicteams.ai/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
