MCP SERVERQueue image and speech generations as a batch, then collect every finished file with one call instead of waiting on each job in turn.
LABSCO SUMMARY
Both submit tools return a task ID and nothing else, and the files exist only once task_barrier returns, which is what makes batching worth doing: fire off several generations to saturate the rate limit, then block once. The price of that shape is that individual jobs are not addressable — there is no per-task status check and no cancel — and task_barrier clears completed tasks as it hands them back, so the results are collected once.
A three-tool asynchronous media server over MiniMax: one submit call for images, one for speech, and a barrier that waits for everything outstanding.
MINIMAX_API_KEY, and a writable outputFile path for each job you submit. MIT licensed.
One command — npx minimax-mcp-tools
USE CASES
Submit one speech job per slide with the voice, emotion and speed settled up front, then call the barrier once. Each job names its own outputFile, so the finished audio arrives already sorted.
Pass the same subjectReference to each image job so the subject holds across the set, vary the prompt and seed per image, then collect the whole batch at the barrier.
Queue the images and the narration together rather than in sequence, since neither blocks. One barrier call returns both sets, which is also the only point at which the files exist.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
submit_image_generationGenerate images asynchronously. RECOMMENDED: Submit multiple tasks in batch to saturate rate limits, then call task_barrier once to wait for all completions. Returns task ID only - actual files available after task_barrier.
submit_speech_generationConvert text to speech asynchronously. RECOMMENDED: Submit multiple tasks in batch to saturate rate limits, then call task_barrier once to wait for all completions. Returns task ID only - actual files available after task_barrier.
task_barrierWait for ALL submitted tasks to complete and retrieve results. Essential for batch processing - submit multiple tasks first, then call task_barrier once to collect all results efficiently. Clears completed tasks.

INSTALLATION
Add the block to your client, or run the command directly.
