Pippit Video
Use the bundled pippit_* tools as the only capability layer. The Codex plugin starts this same MCP server; it does not maintain a second account, generation, or editing implementation.
Configuration boundary
On a local Codex plugin, stdio MCP, or local ChatGPT App install, do not ask the user to configure internal facade credentials. Installation and MCP discovery are side-effect free. On the first actual pippit_* tool call, the shared MCP layer idempotently creates or reconnects to one user-level, loopback-only Pippit Facade runtime. Its internal runtime, management, encryption, job-signing, and ChatGPT media-signing keys stay in private user state outside the plugin cache and project directory. Codex/stdio previews use the host-proxied MCP resource bridge and do not expose a loopback or upstream media URL.
The Codex Dev App, stable gateway/worker generations, and detached local Facade have independent lifecycles. A Dev cold refresh authenticates the Facade under that Dev runtime root and compares its exact entry plus SHA-256 artifact identity with the gateway bundle. It reuses only an exact match and replaces any authenticated non-exact daemon only after the old process exits; a manually bumped version never overrides the artifact identity. It must never stop a daemon from another runtime root or erase BYOK credentials, runtime secrets, jobs, artifacts, outputs, or idempotency state. Do not diagnose Dev freshness from launched=true alone; require profile status to report a healthy Facade whose artifact matches the gateway.
An operator may instead configure an external facade by setting both PIPPIT_FACADE_BASE_URL and PIPPIT_FACADE_API_KEY. If either one is configured without the other, do not fall back to the local runtime; report the configuration error. PIPPIT_FACADE_MANAGEMENT_API_KEY remains optional in external mode and controls whether the account-management tools are available.
Never ask for, accept, display, or persist a raw Pippit Access Key in a prompt, ordinary environment variable, config manifest, log, or tool argument.
Account management is enabled only when PIPPIT_FACADE_MANAGEMENT_API_KEY is configured. This is a separate facade Management API Key, not a Pippit AK and not the runtime Facade API Key. pippit_add_access_key returns a short-lived loopback setup URL. Ask the user to open that URL and enter the Pippit AK in its password field; never ask them to paste the AK into chat. The enrollment page sends the secret directly to the facade management plane and the tool results contain only masked account metadata.
External mode also reads:
PIPPIT_FACADE_TIMEOUT_MS (default 43200000, 12 hours)PIPPIT_MCP_OUTPUT_ROOT (default ~/Movies/Pippit on macOS or ~/Videos/Pippit elsewhere)
In local mode, every completed image and video output is first saved as an ordinary local file under ~/Movies/Pippit on macOS or ~/Videos/Pippit on other platforms. PIPPIT_MCP_OUTPUT_ROOT overrides this location. PIPPIT_BRIDGE_HOME is only a test/advanced isolation override; when it is set, outputs stay beneath that isolated root. Never suggest placing outputs in a temporary directory, plugin cache, or project checkout.
For Codex/stdio, widgets read persistent local artifacts through standard MCP Apps resources/read and reconstruct sandbox-local blob: URLs. Images use stable pippit-image://artifact/... identities and fall back to the app-only pippit_read_image transport when a historical widget's original resource bridge has ended. Videos use bounded chunks and the app-only pippit_read_video_chunk fallback. These tools are not visible to the model and enforce permission, size, and symlink checks. Neither an upstream signed URL nor a local filesystem path is assigned directly to a preview. A failed bridge must leave loading within a bounded timeout and show a recoverable error.
Workflow
- If no account is configured, call
pippit_add_access_key with a non-secret account name, then have the user complete its loopback setup page. Use pippit_list_access_keys to confirm the masked account is active.
- Use
pippit_switch_access_key to select the account for new jobs. Switching never changes the credential embedded in an existing job id. Before pippit_delete_access_key, show the selected masked account and get explicit confirmation; local deletion does not revoke the AK on the Pippit website.
- For images, call
pippit_list_image_models when needed, then call pippit_generate_image. Omit model to use the default pippit/seedream-5.0 without resolution, or use pippit/seedream-5.0-pro with optional 1K, 2K, or 4K. Up to 9 reference images and n=1..10 are accepted. In Codex/stdio, generation returns an image_job_id immediately so the result card can show Infinity Run progress; poll pippit_get_image until the task completes. Completed bytes are atomically saved locally, and the card previews that stable artifact with an action to reveal it in Finder or the system file manager. If the user asks for the same image or file again, direct them to the existing card or configured output folder and never regenerate it.
- For video, call
pippit_list_video_models when the model or its supported settings are not already known. Omit model to use the officially released default pippit/seedance-2.5; actual submission remains subject to the active Pippit account's upstream entitlement. The production-aligned alternatives are pippit/seedance-2.0-vision, pippit/seedance-2.0-mini, and pippit/seedance-2.0-mini-lite.
- Call
pippit_generate_video once. Omit idempotency_key for an ordinary submission. Only when the user deliberately requests abnormal-recovery protection, choose and preserve a stable key before the first attempt; reuse that key only after an abnormal interruption and only with the exact same arguments. The tool submits a job and returns immediately; it does not wait for generation to finish.
- In the same execution unit as the submission, read the returned opaque job
id directly from structured tool output and persist that exact string before displaying or polling it. In Codex, use the equivalent of and later pass unchanged to . Never transcribe, reconstruct, shorten, decode/re-encode, or manually paste a value. Never pass the shorter such as as ; it is not a polling credential. If the exact job was not preserved, recover it from the original structured tool result or task trace when available. Do not submit a replacement generation merely to recover a lost polling id.
Video editing
Use pippit_edit_video_segment only with a completed source job and a time_range within the source video. The result widget and direct calls default to pippit/seedance-2.0-vision (seedance2.0_vision upstream); a supported Seedance 2.0-family source model is preserved. Seedance 2.0-family edits use the complete source as an ordinary video reference with a positive output duration, while an explicitly selected pippit/seedance-2.5 uses native partial_edit_videos. Seedance 2.0-family ranges must be 4–15 seconds and Seedance 2.5 ranges must be 4–30.2 seconds. Public MCP and ChatGPT arguments use microseconds. For Seedance 2.0-family reference-guided regeneration, time_range, optional guidance_annotations[].at_time_us, normalized intrinsic-frame region, and instruction are prompt guidance rather than a native provider range or hard mask.
The upstream contracts do not expose a pixel mask. Describe the result as regeneration, not as an in-place byte edit or proof that an exact rectangle mask was enforced.
The regeneration returns another asynchronous job. Apply the same opaque job-id rule: persist the exact structured id in the submission execution unit and poll it without transcription or substitution. Its completed result is likewise saved locally first and opens the same preview/regeneration widget. Create an extra copy only under the explicit-copy rule above.
All generation-related tool paths use a 12-hour internal timeout. After Regenerate video is clicked, the widget immediately shows loading and requests the standard MCP Apps inline display mode so a supporting Codex host returns to the conversation while polling continues. Do not send a follow-up chat message to force this transition, because that could trigger a duplicate model turn.
frame_images and input_references use HTTP(S) URLs that the facade resolves. A request containing frame images uses first/last-frame generation semantics. Never mix frame_images with input_references in one request.
Do not claim text, speech, transcription, or audio-generation support. Audio is accepted only as an input reference for a video request.
