"Invoice Ninja" matching MCP servers:

Provides offline validation and analysis of Turkish e-invoice documents (e-Fatura, e-Arşiv, e-İrsaliye) using the official GİB XSD, schematron, arithmetic, and signature rules, returning detailed Turkish explanations and correction suggestions.

Enables LLM agents to query and reconcile an accounts-payable ledger through safe read-only SQL, deterministic invoice-to-payment matching, and exception explanations for underpayments, duplicates, currency mismatches, and overdue invoices. Ships with a synthetic ledger, golden-set evals, and a month-end review workflow so quality can be measured in CI.

Runs a local stdio MCP server that lets you evaluate an AI agent's business outcome against four synthetic scenarios, including a duplicate-free quote follow-up, an unsent invoice reminder, client-file separation, and a stockout. It scores the run from the final state and recorded attempts rather than the agent's text, returning a pass or fail exit code.
