See what an agent can do with Extend before you ever sign up. Pick a story: recorded sessions replay real probe-harness transcripts; commands tagged live-capable can re-run against the real endpoint from our edge, right now (▶ run live — the exact same request, live and recorded lines always labeled); the live MCP handshake runs real requests from our edge, right now — including, where the server allows it, one real read-only tool call (bring your own key for auth-gated servers); sandboxed self-drive sessions are designed and gated (docs/TRY-IT.md).

Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 38 stories with headroom

What would move Extend’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Agenticness — how well agents can access and operate the productPlug MCP servers into this product so it can use their tools

    nonemoves agent-readyimpact 45

    Extend documents 'Using Extend via MCP' (docs.extend.ai/mcp), which describes exposing Extend's own tools via MCP to other agents — this is the opposite direction of the story (product consuming external MCP servers as a client).

  2. Openness — open source, data portability, and self-hosting storiesExport all of my data in open formats and leave

    nonemoves PA Scoreimpact 30

    Extend is a SaaS document-processing platform holding workflows, processors, evaluation sets and extracted data, so data-portability/export is a fair question, but the evidence pack contains no mention of a bulk data-export feature, open-format export of processed data/configs, or account-closure data dump — only retention/ZDR policies which describe deletion, not export.

  3. Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent

    nonemoves agent-readyimpact 30

    Evidence only shows basic API-key authentication (extend-docs-4) and a separate test-vs-production API key for sandboxing (extend-docs-38), but nothing about issuing scoped, role/permission-limited, or least-privilege credentials for individual agents (e.g., granular scopes, RBAC, per-agent key restrictions).

  4. Agenticness — how well agents can access and operate the productDownload a machine-readable API spec (OpenAPI or equivalent)

    nonemoves API qualityimpact 30

    Missing: openAPI/Swagger spec file, documented spec download link, machine-readable API schema.

  5. Agenticness — how well agents can access and operate the productRely on versioned APIs with a documented deprecation policy

    nonemoves API qualityimpact 30

    Evidence shows versioning for internal artifacts (processors, workflows, base models) but no documentation of API endpoint versioning (e.g., v1/v2 paths) or any deprecation/sunset policy for the REST API/SDK itself.

  6. Agenticness — how well agents can access and operate the productDelegate tasks to a built-in AI assistant inside the product

    partialq5/10moves Built-in AIimpact 22.5

    Missing: a documented chat/assistant interface, examples of delegating broader tasks beyond document processing, and independent hands-on confirmation of these agent features in use.

  7. Openness — open source, data portability, and self-hosting storiesSelf-host the core product

    partialq3/10moves PA Scoreimpact 21

    Missing: open-source or downloadable core product, self-hosting setup docs, infrastructure requirements, and independent confirmation that customers can run it fully outside Extend's cloud.

  8. Table extraction — stories about table extraction in this arenaComplex tables — merged cells, nested headers, multi-page spans — come out as faithful HTML/markdown structure

    partialq3/10moves PA Scoreimpact 21

    Missing: explicit handling of merged cells, nested headers, multi-page table continuity, and documented HTML/markdown fidelity examples.
