Overview

AI-generated overview

Remote MCP server that lets an assistant answer questions about a Lightspeed Retail (R-Series) shop's sales, stock, customers and work orders.

What you can do
  • Query a shop's sales data
  • Check stock and inventory levels
  • Look up customer records
  • Review work orders
  • No individual tools are documented in the listing, so the exact operations are not specified; the server is described only as answering questions about these four areas.
When to use it
Useful when you want an assistant to answer everyday questions about a Lightspeed Retail R-Series store — how sales are going, what is in stock, who a customer is, or the status of work orders — without exporting reports by hand.
Requirements
A remote endpoint at tally.backspinlabs.com over streamable HTTP; OAuth authentication is required, so a Lightspeed Retail (R-Series) account connected through that sign-in is needed. No environment variables or headers are declared.
Before you install
The server reaches a shop's business data (sales, inventory, customers, work orders) through OAuth, so review the scopes granted at sign-in and who can access the connected account. The listing does not document which tools exist or whether any of them write, change or delete data.

Installation

In SourceWeft

  1. Open Tally by Backspin Labs 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/com.backspinlabs%2Ftally/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.

Tools

0
This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

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.
