Nusii MCP ServerVerifiedFeatured

What is Nusii?

Nusii is proposal software for agencies and freelancers. Its MCP server lets AI assistants such as Claude, ChatGPT, Gemini and Microsoft Copilot work with your Nusii account.

What an assistant can do

With read access, an assistant can:

• Summarize your proposals and conversion rate over any period
• Find a proposal by its title, document number, client or status
• List your templates and read their content
• Look up clients
• Read a proposal's content and pricing

With write access, it can also:

• Create a draft proposal from one of your templates, or from scratch
• Add, update or remove pricing line items
• Apply taxes to a draft's pricing
• Rewrite sections, add new ones, or remove ones you don't need
• Attach a client to a draft
• Change a draft's settings, such as the theme, the expiration date, or the deposit percentage

What it can never do

• It never sends anything. Assistants only create and edit drafts, and you review and send proposals from Nusii.
• It can't touch accepted proposals. Once a client signs, the proposal is locked.
• It only sees what you see. Access mirrors your Nusii role.

How to connect

Whichever assistant you use, the server address is the same: https://app.nusii.com/mcp

In Claude, Nusii is listed in the connector directory, so connecting is a couple of clicks. In other apps, add the server address and approve access with your normal Nusii login.
