MCP Quotes in Claude Desktop

A priced, VAT-correct quote from chat, turned into an invoice with one call. It quotes a client with line items, VAT and a validity window, sends the quote as pasteable text, tracks it as open, accepted, declined or expired, and turns an accepted quote into a real invoice in the shared invoice store using the quote's own stored lines rather than recomputed prices.

A quote is written in the evening or between calls, in the client people already have open for exactly that kind of task, and quote_send_text hands back plain text ready to paste into whatever mail app is next to it.

What you get in Claude Desktop

You sayTool
Quote Acme for 12 hours at 90 EUR plus a 300 EUR setup, 23% VAT, good for 14 days.quote_create
Acme said yes. Invoice it.quote_accept
What is still open, and what is my win rate?quote_report

A quote of EUR 1,000.00 net is issued at the profile's 23% default rate, so the client sees EUR 1,230.00. The default rate is then changed to 8% before the client answers. quote_accept still invoices EUR 1,230.00, tax_lines[0].rate === 23, because it copies the quote's stored lines instead of recomputing them against today's profile.

Install it in Claude Desktop

The file is claude_desktop_config.json, and the key inside it is mcpServers.

ScopePath
macOS~/Library/Application Support/Claude/claude_desktop_config.json
Windows%APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "quotes": {
      "command": "npx",
      "args": ["-y", "@theluckystrike/mcp-quotes"]
    }
  }
}

If node came from nvm, asdf or homebrew, replace "npx" with the absolute path that which npx prints:

"command": "/Users/you/.nvm/versions/node/v22.14.0/bin/npx"

Save, then completely quit Claude Desktop and start it again. A window reload is not enough.

The npm publish of @theluckystrike/mcp-quotes is pending; until then use the .mcpb bundle or a clone and build from the latest release.

No install: the hosted endpoint

There is no hosted endpoint for this one yet. MCP Quotes runs locally over stdio with the config above, which is also the only form in which it reads and writes files on your own disk. Three of the servers in this collection are served at https://mcp.zovo.one/mcp/<name> over MCP streamable HTTP: time-tracker, price-tracker and invoice.

Claude Desktop notes worth knowing first

Two documented facts decide whether the entry works: every path in claude_desktop_config.json must be absolute, and a stdio server started here inherits only a limited, platform-dependent subset of environment variables. If node came from nvm or homebrew, paste what `which npx` prints instead of the bare word. The .mcpb route avoids both: Claude Desktop ships a built-in Node.js environment.

Free: 5 open quotes at a time, unlimited quote_send_text, create/revise/accept/decline, VAT, discounts and multi-currency. Pro is $19 once, verified offline.

Questions

Where is claude_desktop_config.json?

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json. Windows: %APPDATA%\Claude\claude_desktop_config.json. There is no published Linux path. Settings, Developer, Edit Config opens the right copy and creates it if it does not exist.

I added it and MCP Quotes does not appear.

In order: did you fully quit and restart, not just close the window? Is every path absolute? And is the command resolvable, given the limited environment a stdio server inherits here? If node came from nvm, paste what which npx prints.

Can I install it without editing JSON?

Yes. An .mcpb bundle, the format renamed from .dxt, opens with Claude and shows an installation dialog. One you built yourself goes in through Settings, Extensions, Advanced settings, Install Extension.
