• 🔧 Complete API coverage - Projects, runs, and more
• 🤖 MCP Support - Use Hex directly in Claude Desktop and Claude Code
• 📦 Minimal dependencies - Built on httpx for reliability
• 🔐 Secure - API key authentication with environment variable support

Installation

# Basic installation
pip install hex-toolkit

# With CLI support
pip install "hex-toolkit[cli]"

# With MCP (Model Context Protocol) support
pip install "hex-toolkit[mcp]"

# Install everything
pip install "hex-toolkit[all]"

Quick Start

from hex_toolkit import HexClient

# Initialize the client
client = HexClient(api_key="your-api-key")

# List all projects
projects = client.projects.list()
for project in projects.values:
    print(f"{project.title} - {project.id}")

# Get a specific project
project = client.projects.get("project-id")
print(project.title)

# Run a project
run = client.projects.run(
    project_id="project-id",
    input_params={"param1": "value1"}
)
print(f"Run started: {run.run_id}")

# Check run status
status = client.runs.get_status(project_id="project-id", run_id=run.run_id)
print(f"Status: {status.status}")

Configuration

The client can be configured via environment variables:

export HEX_API_KEY="your-api-key"
export HEX_API_BASE_URL="https://app.hex.tech/api"  # Optional

Or directly in code:

client = HexClient(
    api_key="your-api-key",
    base_url="https://custom.hex.tech/api",
    timeout=60.0
)

Usage Examples

Working with Projects

# List projects with filters
projects = client.projects.list(
    limit=50,
    include_archived=False,
    creator_email="[e-mail]"
)

# Access project data - fields are converted to snake_case
for project in projects.values:
    print(f"ID: {project.id}")
    print(f"Title: {project.title}")
    print(f"Type: {project.type}")  # ProjectType.PROJECT or ProjectType.COMPONENT
    print(f"Created: {project.created_at}")
    print(f"Last edited: {project.last_edited_at}")

Pagination

# List projects with pagination
after_cursor = None
all_projects = []

while True:
    response = client.projects.list(limit=100, after=after_cursor)
    all_projects.extend(response.values)

    # Check if there are more pages
    after_cursor = response.pagination.after if response.pagination else None
    if not after_cursor:
        break

print(f"Found {len(all_projects)} projects total")

Running Projects

# Simple run
run = client.projects.run("project-id")

# Run with parameters
run = client.projects.run(
    project_id="project-id",
    input_params={
        "date_start": "2024-01-01",
        "date_end": "2024-01-31",
        "metric": "revenue"
    },
    update_published_results=True
)

# Run with notifications
run = client.projects.run(
    project_id="project-id",
    notifications=[{
        "type": "ALL",
        "includeSuccessScreenshot": True,
        "slackChannelIds": ["C0123456789"],
    }]
)

Monitoring Runs

import time

# Wait for completion
run_id = run.run_id
project_id = run.project_id

while True:
    status = client.runs.get_status(project_id, run_id)
    print(f"Status: {status.status}")

    if status.status in ["COMPLETED", "ERRORED", "KILLED"]:
        print(f"Run finished with status: {status.status}")
        if status.elapsed_time:
            print(f"Elapsed time: {status.elapsed_time}ms")
        break

    time.sleep(5)

Error Handling

from hex_toolkit.exceptions import (
    HexAPIError,
    HexAuthenticationError,
    HexNotFoundError,
    HexRateLimitError
)

try:
    project = client.projects.get("invalid-id")
except HexNotFoundError as e:
    print(f"Project not found: {e.message}")
except HexAuthenticationError:
    print("Invalid API key")
except HexRateLimitError as e:
    print(f"Rate limited. Retry after: {e.retry_after} seconds")
except HexAPIError as e:
    print(f"API error: {e.message}")
    print(f"Status code: {e.status_code}")
    print(f"Trace ID: {e.trace_id}")

Creating Embedded URLs

# Create a basic embedded URL
embed = client.embedding.create_presigned_url("project-id")
print(f"Embed URL: {embed.url}")

# Create with options
embed = client.embedding.create_presigned_url(
    project_id="project-id",
    expires_in=300000,  # 5 minutes
    input_parameters={"filter": "Q1"},
    display_options={
        "theme": "dark",
        "noEmbedFooter": True
    }
)

MCP (Model Context Protocol) Support

The SDK includes built-in MCP support for using Hex directly within Claude Desktop and Claude Code. Learn more about MCP.

Quick Setup

# Install the MCP server
hex mcp install

# Check installation status
hex mcp status

# Use in Claude - look for the 🔧 icon!

See the MCP documentation for detailed setup and usage instructions.

API Resources

Projects

• client.projects.list(**filters) - List all projects
• client.projects.get(project_id) - Get a specific project
• client.projects.run(project_id, **options) - Run a project

Runs

• client.runs.get_status(project_id, run_id) - Get run status
• client.runs.list(project_id, **filters) - List runs for a project
• client.runs.cancel(project_id, run_id) - Cancel a run

Embedding

• client.embedding.create_presigned_url(project_id, **options) - Create embedded URL

Semantic Models

• client.semantic_models.ingest(semantic_model_id, **options) - Ingest semantic model (Note: File upload support is not yet implemented)

Response Format

All methods return strongly-typed Pydantic models with convenient dot notation access. The SDK automatically converts the API's camelCase fields to Pythonic snake_case:

# Project object - access with dot notation
project = client.projects.get("project-id")
print(project.id)                # "12345678-1234-1234-1234-123456789012"
print(project.title)             # "Sales Dashboard"
print(project.type)              # ProjectType.PROJECT (enum)
print(project.created_at)        # datetime object (converted from "createdAt")
print(project.last_edited_at)    # datetime object (converted from "lastEditedAt")
print(project.creator.email)     # "[e-mail]"
print(project.owner.email)       # "[e-mail]"

# Run response - also uses dot notation
run = client.projects.run("project-id")
print(run.project_id)            # "12345678-1234-1234-1234-123456789012"
print(run.run_id)                # "87654321-4321-4321-4321-210987654321"
print(run.run_url)               # "https://app.hex.tech/app/runs/..."
print(run.run_status_url)        # "https://app.hex.tech/api/v1/projects/.../runs/..."

# Paginated responses have a 'values' attribute
projects = client.projects.list()
for project in projects.values:
    print(f"{project.title}: {project.status}")

Field Name Conversion

The API returns camelCase field names, but the SDK automatically converts them to snake_case for a more Pythonic experience:

• createdAt → created_at
• lastEditedAt → last_edited_at
• runId → run_id
• projectId → project_id
• inputParams → input_params

Type Safety

All responses are validated Pydantic models, providing:

• Auto-completion in IDEs
• Type checking with mypy/pyright
• Automatic validation of API responses
• Clear error messages for invalid data
