Perplexity

Instantly ingest statements using this MCP Server

`upload_statement` lets you drop raw merchant statements straight into your local Claude Desktop environment. Your agent grabs the document, processes the text, and preps the numbers for immediate audit without manual copy-pasting. Following ingestion, `analyze_statement` triggers the processing pipeline to extract hidden fees. You get the extracted fee tables right inside your chat window without leaving your workspace.

Audit processor fees side-by-side

This MCP Server pulls real-world merchant service benchmarks directly into your conversation. This lets your agent compare what your merchant actually pays against actual average industry rates. Run `get_audit` to isolate specific overcharges and junk fees. You will see exactly where the processor padded their margins on interchange fees.

Build client savings proposals on the fly

`list_proposals` lists your active savings projections directly within Claude Desktop. Your agent can retrieve previous drafts or prepare a new client pitch in seconds. Use `get_proposal` to extract the exact pricing breakdowns your client needs to see. This lets you draft a highly accurate, personalized proposal without opening a separate calculator.
