Clearml

MCP server for ClearML: browse projects, search and compare tasks, list datasets and models — all via Model Context Protocol.

• PyPI: https://pypi.org/project/mcp_clearml/
• License: MIT

What you get

This server exposes a curated set of ClearML operations as MCP tools:

• Projects
  • list_of_all_projects: list all projects (id, name)
  • find_project_by_pattern: find by name substring (case-insensitive)
  • get_project_stats: aggregated counters for a project (statuses, users, tags, days)
• Tasks (bulk/filters)
  • get_tasks_core_info: core fields by task ids
  • get_tasks_full_info: core + parameters/metrics/artifacts/models by task ids
  • find_tasks_core_info_by_pattern: IDs by name/status/tags
  • find_tasks_full_info_by_pattern: full profiles by name/status/tags
  • get_tasks_core_info_by_project: stats + core list for a project
  • get_tasks_full_info_by_project: stats + full profiles for a project
• Models
  • find_models_by_pattern: search models by name fragment (includes url/uri when present)
  • find_models_info: info for specific model ids
• Datasets
  • find_datasets_by_project: list datasets in a project (optional recursive)
  • find_datasets_by_pattern: list datasets by partial name
  • get_datasets_full_info: per-dataset sizes, uploader and parsed metadata (csv/csv.gz/json)
• Compare
  • compare_tasks: cross-task summary + aligned metrics + parameters diff

Requirements

• Python >= 3.12
• ClearML account with valid credentials in ~/.clearml/clearml.conf
• Recommended uv to run via uvx without installing globally

---

Quick Start

Prerequisites

Ensure your ~/.clearml/clearml.conf contains your credentials:

[api]
api_server = https://api.clear.ml
web_server = https://app.clear.ml
files_server = https://files.clear.ml

credentials {
    "access_key": "your-access-key",
    "secret_key": "your-secret-key"
}

You can obtain keys in ClearML Settings.

Install / Run

• Install from PyPI:

pip install mcp_clearml

• Run without installation (via uvx):

uvx mcp-clearml

• Local dev:

uv sync
uv run mcp-clearml

---

Run MCP server (stdio)

The mcp-clearml command validates ClearML connectivity and starts an MCP stdio server.

---

Integrations (MCP clients)

Claude Desktop

Config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "clearml": {
      "command": "uvx",
      "args": ["mcp-clearml"]
    }
  }
}

Alternative (if installed via pip):

{
  "mcpServers": {
    "clearml": {
      "command": "python",
      "args": ["-m", "mcp_clearml.mcp"]
    }
  }
}

Cursor

Settings → MCP → Add Server:

{
  "mcp.servers": {
    "clearml": {
      "command": "uvx",
      "args": ["mcp-clearml"]
    }
  }
}

You can also add a rule in .cursorrules to remind using the clearml MCP server for experiment analysis.

Use in Claude Code (or any MCP client)

Add the stdio server with the same command. Then call tools by name (e.g., "find tasks by pattern", "compare_tasks"). Generic MCP UIs will connect over stdio automatically.

---

Examples

• "List projects" → list_of_all_projects
• "Stats for project X" → get_project_stats { project_name: "X" }
• "Find tasks by name fragment and get full details" →
  1. find_tasks_core_info_by_pattern { task_name_pattern: "resnet" }
  2. get_tasks_full_info { task_ids: ["..."] }
• "Compare two tasks" → compare_tasks { task_ids: ["task_id_1", "task_id_2"] }
• "Find datasets by project" → find_datasets_by_project { project_name: "X", recursive_project_search: true }

---

Development

Setup & test locally:

uv sync --extra test
uv run pytest -q

Coverage gate is configured at 65% (see [tool.coverage.*] in pyproject.toml).

Lint/type check:

uv run ruff check --output-format=github src/ tests/
uv run ty check || true

---

Release (GitHub Actions)

• Tests run on all branches/PRs (.github/workflows/tests.yml).
• Tag‑based release (.github/workflows/release.yml):
  1. push tag vX.Y.Z → runs tests (verify)
  2. build wheels/sdist, create GitHub Release with artifacts
  3. optional PyPI publish if PYPI_API_TOKEN is set

See docs/releasing.md for the exact steps.
