- Asset Search — Query your entire connected data ecosystem (tables, dashboards, columns) via natural text to discover lineage and trusted data instantly
- Business Glossaries — Retrieve organizational glossaries containing verified business terms, acronyms, and trusted definitions used by your enterprise
- Classifications & Policies — List active data classifications (like PII or Confidential tags) and configured sharing purposes (data policies) across the estate
- Users & Personas — Inspect registered users and configured access control profiles (Personas) aligned to specific business roles
How it works

Frequently asked questions
Can my AI search for a specific dashboard or data table by keyword?
Yes. Ask the agent to perform an asset search using a natural phrase like 'Q3 revenue report' or 'customer addresses table'. The agent triggers Atlan's semantic asset search, returning linked objects across all connected BI and database sources.
Are custom Atlan Classifications and Tags exposed to the AI?
Yes. The agent can list all organizational classifications configured in Atlan (e.g., Sensitive, Restricted, CCPA). This lets the AI contextualize whether the assets it discovers are safe to be shared globally or subject to governance restrictions.
Can the agent modify or write back metadata to Atlan?
No. This MCP integration focuses strictly on safe discovery and organizational governance retrieval (queries). It guarantees your metadata catalogues remain pristine, acting purely as an active lookup augmentation tool for your agent.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Atlan MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
