## 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.

**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

### 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

### 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
