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
