Overview

AI-generated overview

Remote MCP server with free quote and late-fee calculators plus paid USDC tools for reminder emails, quote packs and a small-business tool stack report.

What you can do
  • Calculate quote totals: line amounts, subtotal, discount, tax, total, deposit and valid-until date
  • Compute late fees on overdue invoices by simple interest or flat fee, with days late, total due and a state-cap caution
  • List free and freemium small-business tools from freesmallbiztools.com, optionally filtered by category
  • Look up prices of the paid tools and the receiving address
  • Generate a late-fee reminder email in a polite, firm or final tone
  • Build a good/better/best quote pack with terms and a cover note, and a one-pick-per-need software stack report
When to use it
Useful for freelancers and small businesses that want an assistant to price quotes, work out late fees on overdue invoices, draft payment reminders, or assemble a low-cost software stack from checked listings.
Requirements
Remote streamable HTTP endpoint at api.freesmallbiztools.com; no authentication, environment variables or headers declared. The three paid tools require payment of USDC via x402 (0.01, 0.05 and 1 USDC), so a wallet able to pay on that protocol is needed.
Before you install
Three tools spend real money in USDC via x402; invalid input is stated not to be charged, but confirm prices with the pricing tool first. The late-fee output carries a state-cap caution and is not legal or tax advice. Reminder emails and quote packs are generated text, not sent by the server, so review before use.

Installation

In SourceWeft

  1. Open Free Small Biz Tools in the dashboard and add it to a workspace.
  2. 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/com.freesmallbiztools.api%2Ftools/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

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
