Overview

AI-generated overview

Hosted Taggun server that lets an assistant OCR receipts from a URL or base64 file and read receipt-validation campaigns and account reference data.

What you can do
  • Scan receipts and invoices from a public URL or base64 data and get structured fields such as merchant, date, tax and totals
  • Validate a receipt against a stored campaign's rules
  • List validation campaigns and read one campaign's rules (dates, merchants, products, fraud checks)
  • Export account reference data as CSV: product categories, known merchants, product codes
  • Check monthly usage and manage the subscription (upgrade, cancel) or file a feature request
When to use it
Useful when you want an assistant to pull structured data out of receipt or invoice images, or to check receipts against Taggun validation campaigns, without writing your own Taggun integration.
Requirements
Remote MCP endpoint; no local install. Sign-in is via OAuth, and the login page asks for your own Taggun credentials. Do not add an Authorization header or API key to the client config. A Taggun account with the Campaign Validation feature is needed for campaign tools.
Before you install
Scan tools are billed per scan against your Taggun quota and plan, even when validation fails, and are never retried automatically. Meta tools can start a paid subscription through a Stripe Checkout link or cancel it, with no refund for the current period. The server's own free tier is 50 tool calls per month; paid plans are billed separately. Receipt content is sent to Taggun and this hosted server.

Installation

In SourceWeft

  1. Open Taggun MCP by usefulapi 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/io.usefulapi%2Ftaggun/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

README

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://taggun.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http taggun https://taggun.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json

POST /api/validation/v1/campaign/receipt-validation/url.

Parametersurlrequirednearlanguagecampaign_idrequiredkeep_stored
