Additional notes for reviewers

Disclosure: we are Eightcell Labs, the company behind Tesseract, which is a paid service.

What the plugin contains:

mcp.json / .mcp.json: one remote server, https://app.tesseract.dev/api/core/tesseract/mcp (Streamable HTTP, OAuth 2.1 with PKCE, no API key). It is also in the official MCP Registry as dev.tesseract/media 1.0.0.
8 tools: list_models, list_effects and check_job are read-only; generate_image, edit_image, apply_effect, generate_video and make_long_video start jobs.
Two skills: make-a-video-ad (turns a request into a shot plan, confirms the price, starts the job, returns the file) and photo-effects (picks an effect from the catalogue and applies it to the user's own photo or clip).

Requirements and limits (also in the README's Cost section): a Tesseract account is needed and jobs are charged to it. The plan's free media each month is used first; after that it is paid. The skills tell the agent to state the price and agree a ceiling with the user before starting a job and to pass it as max_usd, so a job that would cost more is not started. Each connected app also has its own monthly spending limit ($20 by default). The plugin itself is only configuration and Markdown; it runs no code.

Checked locally against this repository's eng/external-plugin-quality-gates.mjs at the pinned sha: Agent Plugins v1.0.0 manifest check passes, and vally lint passes for both skills. We have not run the Copilot CLI install smoke test.

/request-fixes Could you share one successful free-tier Copilot run for a video or catalogue-effect workflow, including how the returned media is delivered and how max_usd and the connected-app spending limit are enforced? Copilot now handles ordinary image generation and editing natively, so the remaining case is Tesseract's distinct video and specialized-effect workflows.

Could you share one successful free-tier Copilot run for a video or catalogue-effect workflow, including how the returned media is delivered and how max_usd and the connected-app spending limit are enforced? Copilot now handles ordinary image generation and editing natively, so the remaining case is Tesseract's distinct video and specialized-effect workflows.

Once you've addressed these, edit the issue or comment /rerun-intake to send it back through intake for review.

Thanks for the review. Here is a free-tier Copilot run of the catalogue-effect workflow, done on 2026-11-13.

Setup

GitHub Copilot CLI 1.0.109, signed in to an account on Copilot Free.
Plugin installed with copilot plugin install opentech-dev/tesseract-claude-plugin → tesseract (v1.0.0), 2 skills.
The Tesseract side is a test account, connected through Tesseract's OAuth flow (dynamic registration, PKCE, consent page). In Tesseract → Settings → Account → Connected apps, that connection's monthly spending limit was set to $1.
The test machine has no browser, so the run passed the OAuth access token to the server as a header with --additional-mcp-config. In an interactive Copilot session the same sign-in opens as a web page.

1. max_usd below the quote: refused before anything starts

Copilot read the effect's guide price from list_effects ($0.20) and passed max_usd: 0.2. The server's quote for the job was $0.25:

✗ Apply an effect — This costs $0.25, above the $0.2 you set as the most (max_usd). Nothing was sent.

2. A job within max_usd: the media comes back as a file link

Copilot ran apply_effect (Product Showcase, a 5 s 720p clip) on an image, with max_usd: 0.25:

It is being made. Price: at most $0.25 …

It polled check_job until it answered Done, then printed the result: a short-lived signed download link, https://app.tesseract.dev/api/core/tesseract/mcp/files?t=…, pointing to the MP4. The charge was $0.20, the provider price, with the plan's free media used first. The connection's spend this month went from $0.00 to $0.20.

A job that fails costs nothing. An earlier attempt used an image URL the provider could not download; check_job answered failed / provider_refused with "A job that fails is not charged", and the spend did not change.

3. The connected app's monthly spending limit: refused when the job would pass it

The connection's limit was lowered to $0.21 (with $0.20 already spent), and the same job was asked for again:

✗ Apply an effect — This costs $0.25, more than is left of this app's monthly spending limit. Nothing was sent. Raise the app's limit in Tesseract → Settings → Account → Connected apps.

Total charged across the run: $0.20. The plugin itself runs no code locally. Every price is checked on the server, against both the per-call max_usd and the app's monthly limit, before a job is sent to a provider.
