Before you call either

LlamaParse API + MCP

  1. Connect to a product endpoint such as https://mcp.llamaindex.ai/parse/mcp instead of the unified one to load 3 tools plus helpers
  2. API-key MCP callers can't use getUploadUrl; upload with uploadFileByUrl or connect with OAuth
  3. Pin version on every parse so tier behaviour stays reproducible
  4. Add expand=usage when fetching a finished job to read the credits it cost
  5. Treat a 402 as out of credits, not a transient error

Unstructured API + MCP

  1. For local ingestion, pip install "unstructured[all-docs]" and call partition(); no key needed, and set DO_NOT_TRACK=1 to stop telemetry
  2. Transform returns 202 with a Location header for long parses; poll it, then pass the parse id as parse_id to Extract
  3. Uploaded files expire after 24 hours; keep the original and re-upload on a 404
  4. Treat 409 parse_expired and 410 result_expired as a signal to rerun the parse, not to retry
  5. Check for an existing job ID before resubmitting, since there's no idempotency key
