Overview

AI-generated overview

Remote MCP server for SolidInvoice, an invoicing platform, letting an assistant create and send invoices and quotes, manage clients and track payments.

What you can do
  • Create and send invoices and quotes, including converting quotes into invoices
  • Manage clients and contacts, with per-client currency, addresses and custom fields
  • Track payments and payment status against issued invoices
  • Work within a multi-company account, since the platform supports multi-tenancy
When to use it
Useful when you bill clients through SolidInvoice and want an assistant to draft or send invoices and quotes, look up client records, or check payment status without opening the web app.
Requirements
A remote MCP endpoint at solidinvoice.app reached over streamable HTTP, with OAuth sign-in required. No environment variables or headers are declared. A SolidInvoice account (hosted or self-hosted) with the relevant company data is needed.
Before you install
The server can create and send invoices and quotes and change client records, so actions affect real billing and customers. Access is granted through OAuth to your SolidInvoice account, which holds client and payment data. Hosted plans are paid from $9/month after the free tier; self-hosting is free but you maintain it.

Installation

In SourceWeft

  1. Open SolidInvoice in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

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/co.solidinvoice%2Fmcp/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.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Why SolidInvoice?

Built on Symfony 8.1 and PHP 8.4, it's designed to be extended, integrated, and trusted.
