## 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
