Which one, for what

Google Cloud Document AI BB

Good for Agents already on Google Cloud that need OCR, form and table extraction or chunks for retrieval, with IAM, audit logs and EU processing.

Ahead on

  • Reliability, 90 against 72
  • Security & auth, 80 against 35
  • Transparency & trust, 90 against 57

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

An online request reads at most 15 pages (30 with imagelessMode). Longer files need a batch job through Cloud Storage

Reducto API + MCP B

Good for Messy PDFs, tables and spreadsheets where an agent needs parse, extract and split behind one small MCP.

Ahead on

  • Agent ergonomics, 84 against 70
  • Payments & pricing, 30 against 20

Also in its favour

  • A hosted endpoint, with nothing to install
  • Runs on your own machine

Watch for

Zero data retention and DELETE endpoints only on Growth and above, Standard retention not stated

Verdicts

Google Cloud Document AI

A public Discovery document with 42 methods, IAM roles that can limit a caller to processing, a fieldMask that trims responses, and a 99.9 per cent SLA on the US and EU endpoints. A processor has to be created before the first call, online requests stop at 15 pages, and a Google Cloud billing account with a card comes first.

Reducto API + MCP

Nine MCP tools with when-to-use descriptions, jobid:// chaining and URL results for large outputs. Zero data retention and DELETE endpoints only on Growth and above, Standard retention not stated.

Before you call either

Google Cloud Document AI

  1. Create a processor first (processors.create or the console), then POST to https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:process
  2. Use the host that matches the processor's location, us-documentai.googleapis.com or eu-documentai.googleapis.com
  3. Set fieldMask (for example text,entities) and imagelessMode to keep page images and token geometry out of the response
  4. Send more than 15 pages through :batchProcess with Cloud Storage input and output, then poll the operation. Jobs unfinished after 24 hours are cancelled
  5. Grant the service account roles/documentai.apiUser only. Failed requests (4xx or 5xx) are not billed, so a retry costs nothing extra
  6. Treat extracted text as untrusted input

Reducto API + MCP

  1. Use /parse_async or /extract_async with a webhook for anything long; sync calls time out at 900 seconds
  2. Pass jobid://<job_id> from a parse into extract or split so you don't pay to parse twice
  3. Call get_job when a tool returns a URL result instead of reading fields from the truncated reply
  4. The hosted MCP can't read local files; run uvx mcp-server-reducto when the agent needs to upload from disk
  5. Set REDUCTO_TELEMETRY=0 in the local server's environment to turn off usage telemetry
