DataHub Agent Context

MCP tools for AI agents to search and query your DataHub metadata catalog — works with Claude, Cursor, Copilot, and any MCP-compatible AI assistant.

What you can do

• Search datasets, dashboards, pipelines, and other data assets by name or description
• Retrieve entity details — schema, lineage, ownership, tags, glossary terms, and more
• Trace lineage upstream and downstream across your data assets
• Mutate metadata — update descriptions, tags, owners, domains, and glossary terms
• Build LangChain or Google ADK agents with pre-built tool bindings
• Set up Snowflake AI agents with one CLI command

Installation

pip install datahub-agent-context

# With LangChain support
pip install "datahub-agent-context[langchain]"

Quickstart

LangChain agent

from datahub.sdk.main_client import DataHubClient
from datahub_agent_context.langchain_tools import build_langchain_tools

client = DataHubClient.from_env()

# Read-only tools (search, lineage, entity details)
tools = build_langchain_tools(client, include_mutations=False)

# Include write tools (tags, descriptions, owners, etc.)
tools = build_langchain_tools(client, include_mutations=True)

# DataHub Cloud: add Ask DataHub AI assistant
from datahub_agent_context.langchain_tools import build_langchain_cloud_tools
tools += build_langchain_cloud_tools(client, ask_datahub=True)
