Summarize with AI:

Agents that sail through demos on synthetic data tend to collapse on first contact with real business data. A single customer record often spans Salesforce, Zendesk, and Stripe, with the deal, open tickets, and overdue invoice split across systems. At runtime, the agent has to stitch them together, calling each system's application programming interface (API) in sequence, which burns tokens, trips rate limits, and returns partial pages it mistakes for complete answers. Giving the agent a unified layer it can query directly removes that assembly from the request path. This article compares five platforms built for that job, starting with Airbyte Agents.

TL;DR

Runtime API assembly makes agents brittle: latency stacks per source, raw payloads flood the context window, and errors cascade into retry loops.
Airbyte Agents pre-index business entities from 50+ SaaS sources into a managed layer, cutting tool calls and token use against direct API calls.
Microsoft Fabric, Snowflake Cortex, and Databricks Mosaic AI all require your data inside their platform before agents can reason over it.
Glean covers unstructured enterprise knowledge well but routes structured queries through partner integrations.

Try Airbyte Agents to give your agents unified access to business data across every connected SaaS tool in minutes.

Why Is Querying and Unifying Business Data So Hard for AI Agents?

The same Acme account often appears as three separate records across the customer relationship management (CRM) system, the support desk, and billing. An agent connected to each system separately can fetch any of those rows, but it cannot see that they describe the same customer. It finds the deal and misses the three open tickets and the overdue invoice behind it. That entity fragmentation, more than model quality, is what breaks cross-system questions in production.

Runtime assembly makes it worse on every axis. Four sequential API calls at roughly 500 milliseconds each cost over two seconds of input and output before the agent generates a single token of reasoning. Raw payloads flood the context window with pagination metadata and unused fields. An agent can also mistake an authentication-error response for data, or reason over a truncated first page as if it were the complete dataset.

A unified context layer moves that work out of the agent's live reasoning loop. A managed replica pre-indexes a curated subset of business entities from connected systems and keeps them current on a schedule. The agent then searches one consistent, typed layer, and that requirement shapes the comparisons below.

Which Tools Query and Unify Business Data?

We evaluated each platform on connector breadth, token efficiency, cross-system reasoning, latency, and the maintenance burden it leaves with your team. Release status matters too, since several entries ship core features in preview or beta. The five below take noticeably different approaches to the same problem.

Airbyte Agents

Airbyte Agents replicates selected SaaS entities into a managed store before an agent request, so context assembly happens outside live reasoning. When processing a prompt, it chooses between a store search that handles filters, sorts, and aggregations without a third-party call and a direct request that hits the live API for the freshest data and every write. Its public benchmark harness recorded 40% fewer tool calls than vendor-native connectors and 80% fewer tokens than direct API calls.

Over 50 agent connectors, including Salesforce, Stripe, Zendesk, Gong, Linear, and Slack
Four shared interfaces: web app, Agent MCP, Agent SDK, and API
A uniform execute(entity, action, params) call for list, get, search, create, update, and delete

Airbyte Agents fit small teams that need cross-SaaS access without ingesting everything into a warehouse. Your service reaches the same connectors and credentials as typed Python tools, and a free tier starts at zero dollars.

Microsoft Fabric + Copilot Studio

Microsoft's Fabric Data Agent answers plain-English questions over enterprise data using read-only SQL, Data Analysis Expressions (DAX), and Kusto Query Language (KQL) that users never write themselves. Those queries run against data that already lives in OneLake, Microsoft's unified data lake. The Copilot Studio integration, in preview as of July 2025, uses MCP to route data-heavy questions from a custom Copilot agent to the Fabric data agent.

The core Fabric Data Agent has reached general availability
Purview governance and interaction audit logs are built in
Reaching external stores like Snowflake or Cosmos DB requires mirroring them into Fabric first

Fabric fits organizations already standardized on Microsoft data tooling. Governance and audit logging are strong, but each agent caps at five data sources, the path is read-only with no write-back, and the Copilot Studio route needs a Microsoft 365 Copilot license per builder.

Snowflake Cortex Agents

Snowflake Cortex Agents, in public preview since February 2025, run a three-phase loop inside Snowflake's governed perimeter: plan the subtasks, call tools, then reflect on results. Cortex Analyst translates natural language into SQL and self-reports 90% accuracy on their internal text-to-SQL benchmark. At the same time, Cortex Search runs hybrid vector-and-keyword retrieval over text stored in Snowflake. Snowflake hosts the default models, so no data, metadata, or prompts leave its governance boundary.

Cortex Analyst and Cortex Search have both reached general availability
Data, metadata, and prompts stay inside Snowflake's governance boundary
Analyst queries Snowflake tables only, and Search indexes Snowflake-stored text only

Cortex fits teams whose operational data already lands in Snowflake. The governed perimeter is its strength and its main constraint, since there is no documented live-query path to external SaaS APIs, so every piece of multi-SaaS operational data needs an upstream ingestion pipeline first.

Databricks Mosaic AI

The Mosaic AI Agent Framework, branded Agent Bricks, builds tool-calling agents, retrieval-augmented generation applications, and multi-agent systems, with Unity Catalog enforcing access control on each interaction. Managed MCP servers, in public preview, connect agents to Unity Catalog tables, vector search indexes, Genie agents, and custom functions, each behind its own URL and OAuth scope. MLflow 3 adds tracing across more than 20 frameworks, built-in judges, and online monitors that score incoming traces.

Unity Catalog governance pairs with MLflow tracing, judges, and online monitors
Fine-grained controls include row filters, column masks, and attribute-based access control (ABAC)
Setup on Amazon Web Services requires S3 buckets, identity and access management (IAM) roles, policies, and cross-account trust

Databricks fits teams already invested in the lakehouse and willing to run its governance stack. The controls and observability are extensive, but you must govern data through Unity Catalog before agents can reach it, and the account-level metastore plus Premium plan make setup heavy.

Glean

Glean focuses on unstructured enterprise knowledge. More than 250 connectors feed its Enterprise Graph, and in 2026 it launched independent agents with their own scoped credentials, persistent presence, and audit trails. Its architecture documentation states plainly that it does not ingest or index structured data from systems like Snowflake or Databricks.

Over 250 connectors cover unstructured and conversational content
Agents carry identity, memory, and audit trails
Structured queries route through partner integrations such as Snowflake Cortex Analyst and BigQuery

Glean fits knowledge-heavy search across documents and conversations. Structured coverage is the limitation, since there is no native index of warehouse data, and high-latency requests through the Snowflake integration can time out.

How Do These Tools Compare on Data Unification?

The five platforms differ most in how much data you must move before an agent can query it, and in whether they cover structured and unstructured sources together. The table below lines them up on the criteria that matter for querying and unifying business data.

Tool	Connector Breadth	Data Relocation Required	Structured + Unstructured	Write-Back
Airbyte Agents	50+ SaaS connectors	No, queries in place	Yes	Yes
Microsoft Fabric + Copilot Studio	Sources mirrored into OneLake	Yes	Yes	No, read-only
Snowflake Cortex Agents	Snowflake-resident data only	Yes	Yes, SQL and text	Limited
Databricks Mosaic AI	Unity Catalog governed data	Yes	Yes	Yes
Glean	250+ connectors	Ingested into Enterprise Graph	Unstructured only	Through scoped agents

The pattern holds across the set. The warehouse and lakehouse platforms ask you to centralize data first, Glean covers documents, but not structured records, and only Airbyte Agents query live SaaS entities in place across both data types.

Which Is the Best Option for Unifying Multi-SaaS Business Data?

The best option depends on where your data already lives. When operational data has consolidated inside Microsoft Fabric, Snowflake, or Databricks, the native agent on that platform reasons over it without another integration, and each one enforces mature governance. Glean is the stronger pick when the questions center on documents and conversations rather than structured records.

For agents that must reach business data still scattered across many SaaS tools, Airbyte Agents fits best in this set. It is the only option here that queries live entities in place across both structured and unstructured sources, without first relocating data into a warehouse or lakehouse. Airbyte maintains the connectors, authentication, and pagination below the agent, so a small team spends its time on agent behavior rather than data plumbing.

Ready to Give Your Agents Unified Business Data?

Entity fragmentation, more than model quality, is what breaks agents in production, and the fix is architectural. You move cross-system assembly out of the live reasoning loop and into a layer the agent can query in one call. Every tool here makes a different trade between governance, coverage, and how much data you have to relocate first.

Airbyte Agents applies that pattern to multi-SaaS operational data, with a searchable store of pre-indexed entities, a direct API fallback for the freshest reads and every write, more than 50 connectors that Airbyte maintains, and typed results your agents can filter without cleanup.

Frequently Asked Questions

What Is an AI Data Agent?

An AI data agent perceives information from its environment, reasons over it, and takes actions toward a goal. A chatbot follows execution paths fixed at design time, while an agent directs its own execution, choosing the next step, selecting tools, and judging whether results are sufficient.

How Does a Context Store Differ From a Vector Database or Data Warehouse?

A context store holds typed, unified business entities such as accounts, deals, and tickets, replicated from source systems and searchable inside an agent's reasoning loop. A vector database stores embeddings for similarity search, while a context store adds entity unification and typed field filters. A data warehouse serves analytical SQL over historical data and can take minutes per query, which is too slow for a live agent lookup.

How Does Unified Data Reduce Agent Errors?

Many production agent failures trace back to the data access layer, where agents mistake empty results, timeouts, and partial pages for valid responses and then reason confidently over bad inputs. Unified data hands the agent complete, typed entities before tool discovery, and a direct-request fallback lets it verify live state before a consequential decision.

What Security Controls Should I Evaluate?

Look for audit logs that capture agent identity, delegated user, resource, action, and authorization decision. When an agent acts for a user, permissions should intersect rather than combine, credentials should stay isolated per workspace or tenant, and managed OAuth should refresh tokens automatically. Certifications such as SOC 2 Type II and ISO 27001 also matter.

Do These Tools Replace My Existing ETL?

No. Extract, transform, load (ETL) pipelines still have their place. Agent connectors provide per-entity access for live reads and writes, and they complement the replication connectors that load your warehouse. Warehouses still serve business intelligence, analytics, and machine-learning training, and teams can run governed replication and agent connectors side by side.
