albumentationsx-mcp 1.15.0

Model Context Protocol server for AlbumentationsX augmentation previews, validation, and segmentation review.

AlbumentationsX MCP

Model Context Protocol server for AlbumentationsX: transform discovery, pipeline validation, deterministic previews, feedback loops, and reproducible exports for computer vision.

Purpose

AlbumentationsX MCP is a thin, typed MCP layer around existing AlbumentationsX primitives. It helps MCP hosts:

• discover transforms and schemas from albu-spec;
• recommend and validate augmentation pipelines;
• render local batch previews and compare preview runs;
• record concrete feedback such as too_noisy:high;
• export accepted pipelines and review reports.

The server does not execute arbitrary Python, fetch remote images, overwrite datasets, or train models. Local preview access is bounded by --allowed-root, and generated artifacts are written under --artifact-root.

Quick Start

Run the published server:

uvx --from albumentationsx-mcp albumentationsx-mcp

For local development:

uv sync --all-extras --dev
uv run albumentationsx-mcp

For preview work, scope filesystem access explicitly:

uvx --from albumentationsx-mcp albumentationsx-mcp \
  --allowed-root /absolute/path/to/images \
  --artifact-root /absolute/path/to/albu-artifacts

Copyable host snippets are in examples. Full setup is in docs/INSTALL.md; the guided trial is docs/FIRST_10_MINUTES.md.

Host Workflow

After connecting an MCP host:

1. Read albumentationsx://examples/client-smoke.
2. Call run_host_smoke_check.
3. Continue only when preview_ready is true.
4. For a real folder, call plan_dataset_onboarding to sample local images and detect common dataset layouts safely.
5. Replace or reuse the paths in preview_request_template.request.
6. Call validate_preview_request before rendering user-provided paths.
7. Call render_preview_batch on a small local image set.
8. Inspect the contact sheet, then use adjust_pipeline, compare_preview_runs, and export_pipeline.

If preview setup fails, read albumentationsx://diagnostics/guide and call diagnose_environment. Troubleshooting details and remediation_actions are documented in docs/USAGE.md and docs/INSTALL.md.

Capabilities

• Transform search and schema inspection.
• Recipe and pipeline recommendation for classification, detection, segmentation, OCR, and balanced workflows.
• Pipeline validation and explanation before rendering.
• Preview request validation for missing files, outside-root paths, masks, and annotation counts.
• Read-only dataset onboarding that detects common layouts and builds bbox/mask-aware first-preview templates.
• Deterministic single-image and batch previews with contact sheets.
• Preview comparison with quality_summary and suggested feedback tags.
• Concrete preview feedback, interactive tuning sessions, ranking, dataset scoring, and visual reports.
• Agent workflow resources, prompts, smoke checks, diagnostics, and release-safe contract snapshots.

The public MCP surface is kept stable through reviewed contract snapshots. Compatibility rules are in docs/COMPATIBILITY.md.

The community guide was accepted upstream in AlbumentationsX#289; source: docs/integrations/mcp.md.
