Xplainable MCP Server

Xplainable MCP Server

A Model Context Protocol server for the Xplainable platform. It lets an LLM agent (Claude, or any MCP client) train, deploy, optimise, and explain transparent machine-learning models through a small set of goal-oriented workflow_* tools.

Training runs server-side on Xplainable's agentic pipeline — the MCP host never fits a model locally.

Two Ways to Use It

1. Hosted — connect your MCP client to https://mcp.xplainable.io (OAuth login, no installation).
2. Local — run the server yourself over stdio with an Xplainable API key. This is what the rest of this README covers.

Quick Start (Local)

1. Get an API key

Create one at platform.xplainable.io.

2a. Claude Code

claude mcp add xplainable \
  -e XPLAINABLE_API_KEY=your-api-key-here \
  -- uvx --from git+https://github.com/xplainable/xplainable-mcp-server.git xplainable-mcp

2b. Claude Desktop

Add to your MCP settings file:

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

{
  "mcpServers": {
    "xplainable": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/xplainable/xplainable-mcp-server.git", "xplainable-mcp"],
      "env": {
        "XPLAINABLE_API_KEY": "your-api-key-here"
      }
    }
  }
}

No uv? Clone and install instead:

git clone https://github.com/xplainable/xplainable-mcp-server.git
cd xplainable-mcp-server
python -m venv .venv && source .venv/bin/activate
pip install -e .

then use "command": "/path/to/xplainable-mcp-server/.venv/bin/xplainable-mcp" (no args) in the config above.

3. Try it

Ask your agent: "What models and datasets do I have?" — it should call workflow_list_assets.

The Workflow Loop

The curated workflow_* tools cover the whole journey:

1. workflow_list_assets — find a dataset (and see existing models / deployments)
2. workflow_train_model(dataset_id, goal, model_name) — returns a run_id
3. Loop: workflow_wait_for_update(run_id) — narrate progress as events arrive; if a decision is pending, relay it to the user and submit their answer via workflow_decide (the run's two gates: label selection and training approval)
4. workflow_deploy_model(model_id) — deploy after the run completes (there is no deployment gate inside the run)
5. Act on the model: workflow_optimise_model / workflow_predict (scores rows with the trained model via the platform inference route — no deployment needed) / workflow_explain_model / workflow_create_report

Tool Surface

By default the server registers the curated surface: 28 tools — the 9 workflow_* tools above, plus 16 curated read/health tools across datasets, models, deployments, optimisers, runs, agentic state, and gateway health, plus 3 team-selection tools (list_user_teams, set_active_team, select_team).

Set XPLAINABLE_ADVANCED_TOOLS=1 (accepted values: 1, true, yes) to register the full surface (~104 tools), adding write/admin tools for preprocessing, monitors, GPT reports, inference, and low-level agentic run control.

Tool files under xplainable_mcp/tools/ are auto-generated from @mcp_tool-decorated client methods (see "Synchronization with xplainable-client" below) — each tool carries tags (e.g. curated, workflow, read, write) that drive this gating. Do not hand-edit generated tool files.

Configuration

See .env.example. The API key is read from the environment only and is never exposed through a tool.

CLI

xplainable-mcp-cli list-tools            # list all available tools
xplainable-mcp-cli validate-config       # check env configuration
xplainable-mcp-cli test-connection       # test API connectivity
xplainable-mcp-cli generate-docs         # generate tool documentation

Docker (HTTP mode)

cp .env.example .env   # fill in your API key
docker compose up --build

The container serves streamable-HTTP on port 8000 with a /health endpoint. For anything beyond localhost, terminate TLS at a reverse proxy.

Development

git clone https://github.com/xplainable/xplainable-mcp-server.git
cd xplainable-mcp-server
pip install -e ".[dev]"

pytest            # run tests
ruff check .      # lint

Synchronization with xplainable-client

Tool files are generated from the xplainable-client package:

# Check if sync is needed / regenerate tool files
python scripts/sync_workflow.py --sync-files

# Generate a detailed report
python scripts/sync_workflow.py --markdown sync_report.md

See examples/SYNC_WORKFLOW.md and examples/sync_scenarios.md for the full process. Run the sync with the pinned xplainable-client version installed, and with Python 3.11+.
