Verdicts

Extend API + MCP

Hosted MCP with OAuth scoped to workspaces and to test or production, and a tools filter with nine groups. Parse is billed on top of Extract, Split and Classify, so Performance Extract costs 5 credits a page.

Veryfi API + MCP

Typed fields and line items for receipts, invoices, cheques, bank statements and tax forms. API outage on 29 September and degraded, incomplete extraction on 1 October.

Before you call either

Extend API + MCP

  1. Connect with https://mcp.extend.ai/mcp?tools=parse,extract,files to keep the schema small
  2. Every MCP call names a workspace and TEST or PRODUCTION; start in TEST
  3. Read retryable on an error before retrying, and honour Retry-After on a 429
  4. Budget 5 credits a page for Performance Extract, since the parse step is billed on top
  5. Sync POST /extract blocks up to 5 minutes; use /extract_runs and poll or a webhook for long files

Veryfi API + MCP

  1. Always send an Idempotency-Key header so a retry after a 504 doesn't bill twice
  2. Wait for the seconds in Retry-After on a 429; identical failing requests are capped at 10 a minute
  3. Set the CLIENT-ID header on every call
  4. Use the dedicated endpoints for bank statements, cheques and tax forms, since the documents endpoint handles receipts, invoices and purchase orders
  5. Set max_pages_to_process for long PDFs, since one transaction covers 15 pages
