Why: Agent access to context
Alation: Ontologies can be published as an MCP server, but that feature was in early access as of 17 September 2026.
Source: Alation AIOS: Ontologies
Euno: Serves context to agents through an MCP server and a Context API (up to 500K or 1M calls by plan), scoped by persona; Claude and Cursor are named.
Source: Euno: Context for AI Agents
Why: Cross-stack lineage
Alation: Builds lineage from SQL queries, scripts and query logs; AI Governance adds agent lineage tracing.
Source: Alation connectors
Euno: Column-level lineage from sources through BI dashboards to AI agents, including business logic inside BI workbooks.
Source: Euno: Context for AI Agents
Why: Automated context build
Alation: Agents auto-draft ontologies, but that feature is in early access; generally available pieces focus on semantic models and AI governance.
Source: Alation press release: AIOS expansion with six products
Euno: Maps assets automatically from day one and precomputes the context graph from APIs and query logs; Euno states zero onboarding lift.
Source: Euno homepage
Why: Governance agents can use
Alation: AI Governance (generally available) traces agent lineage and connects to agent registries; Governed Collections bring documents under governance.
Source: Alation press release: AIOS expansion with six products
Euno: Governance rules become live labels (for example certified or PII-free) that propagate through the graph, with persona-based access to context.
Why: Business definitions and metrics
Alation: Semantic Model Mastering (generally available) ingests, governs and syncs Databricks and Snowflake semantic models; Ontologies use OWL, RDF and SHACL.
Source: Alation press release: AIOS expansion with six products
Euno: Extracts definitions from BI workbooks and SQL and syncs dbt with Looker; it does not offer a semantic layer of its own.
Why: Answer quality checks
Alation: Agent lineage tracing shows what an agent touched; testing agent answers is not described.
Source: Alation press release: AIOS expansion with six products
Euno: Context Calibration generates benchmark questions, checks agent answers and suggests missing rules and glossary terms.
Why: Integration breadth
Alation: Lists 120+ pre-built connectors.
Source: Alation connectors
Euno: Plans cap integrations at 3, 5 or 10; the full source list could not be read.
Source: Euno pricing
Why: Pricing transparency
Alation: Contact form only; Alation says new products are included in its all-inclusive pricing.
Source: Alation pricing
Euno: Tiers, resource limits and a feature table are published, priced by data assets with unlimited users and agents, but no dollar prices.
Source: Euno pricing
Why: Deployment options
Alation: Cloud or self-hosted deployment is not stated on the pages read.
Source: Alation homepage
Euno: Cloud-native SaaS only, reading metadata only; no self-hosted or open-source option is described.

Which hops from warehouse to agent does each document?
Alation: documents 4 of 5 stages
Euno: documents 5 of 5 stages

Which should you choose?
Choose Alation if
- you connect many sources and tools

Choose Euno if
- you need many ways for agents to reach context
- you need lineage from the warehouse through BI to the agent
- Data teams that want agents grounded in lineage and governance across warehouse, dbt and BI without finishing a semantic layer first
