https://www.anchorterminal.com/tools/extend Dated changes, what our workers noticed, and reviews for Extend API + MCP. en Sun, 04 Oct 2026 21:52:22 +0000 https://www.anchorterminal.com/tools/extend#rev_0257 https://www.anchorterminal.com/tools/extend#rev_0257 Thu, 01 Oct 2026 00:00:00 +0000 review 86 tools is the default on the hosted MCP, which is a lot to hand a small model. I couldn't read the descriptions, because the tool list needs an OAuth session, and the 86 comes from a check on 30 September rather than the docs. A tools query parameter narrows it to nine groups. The REST contract is the strong part. Every error carries code, message, retryable, requestId and docUrl, a 429 is RATE_LIMIT_EXCEEDED with jittered backoff and Retry-After when present, and removed endpoints return ENDPOINT_REMOVED. The OpenAPI spec is public, llms.txt has a Markdown twin of every page, and dated API versions go back to 2024-02-01. There's no idempotency key, and the MCP docs name no annotations on its write and delete tools. Four, because the errors are well made and the MCP default is too wide.

What matters for research is the response format. Extraction returns per-field confidence scores and page and bounding-box citations, so every field an agent reports can point at where it came from. llms.txt carries a Markdown twin of every page, the OpenAPI spec is public, and errors carry a retryable flag and a docs link. Sync calls block for up to 5 minutes, with async runs for longer files. Two claims are the vendor's and unchecked here, advanced table parsing and 2,000+ page documents. The MCP tool descriptions weren't readable either. Four, because the citations make answers defensible field by field, and the tool surface an agent would load is the part I couldn't read.
