email receipt classifier

The problem

Manual expense tracking is prone to error and consumes hours of administrative time. Developers and finance teams struggle with fragmented receipts, unverified tax IDs, and the risk of forwarding incorrect data to accounting systems.

What it does

• Classifies business expense receipts automatically from email streams.
• Validates tax details including VAT numbers and IBANs before processing.
• Vets client information to ensure accuracy before invoicing.
• Forwards verified documents directly to designated finance email addresses.
• Manages session state and caching to reduce redundant API calls and processing time.

Frameworks & tools

This skill interfaces with the email_receipt_classifier MCP server. It requires IMAP configuration and environment variable management for credentials.

Why this beats prompting it yourself

Generic prompts often hallucinate tax data or fail to handle technical errors like rate limits and missing credentials. This skill includes specific logic for handling MCP tool outputs, session memory, and strict validation rules that prevent data invention.

Use cases

• Automate the collection of employee receipts for monthly bookkeeping.
• Verify international VAT numbers to ensure tax compliance on invoices.
• Batch process and forward audited receipts to a central finance inbox.
• Check IBAN validity before initiating vendor payments.

Known limitations

Requires the IMAP_PASSWORD environment variable to be configured in a .env file. It cannot function without an active MCP server connection.
