The Governed Context Layer
Reach
Everything your agent is allowed to touch
Your databases, your catalog, your object storage, and the software your team already pays for, all behind one endpoint your agent connects to once.
Integrations
Query across PostgreSQL, MySQL, BigQuery, MongoDB, and the rest through one SQL interface, with catalog coverage and object storage on the same endpoint.

API Gateway
Salesforce, Stripe, and your own internal services become tools the agent can call, through the same logged connection as your data and with nothing custom to build per service.

The difference between an answer and the right answer
A query result on its own is just rows. These four surfaces are what turn it into something a person can act on, and what makes the next answer better than the last.
Semantic Enrichment
Every tool response arrives carrying ownership, quality scores, PII warnings, and glossary definitions from the complementary services. One enriched call does the work of five.

Memory
Persistent knowledge across sessions, recalled automatically by entity, by meaning, or by lineage. The platform remembers what you taught it.

Knowledge Capture
A correction someone makes in passing becomes documentation the whole organization holds: captured in the conversation, reviewed by a person, and reversible if it turns out to be wrong.

Catalog Governance
Your tag vocabulary, business areas, and glossary are curated in the same portal the agent works through, under the same access rules and the same audit log.

Who can ask what, and what happened after
Access is decided when a tool runs, not described in a policy document. The portal is where your team sees the work, and email is how it reaches whoever is not looking at the portal.
Governance
Access control, audit trails, and quality signals enforced by the same platform that executes the query, at the moment it executes.

Portal Tour
The workspace your practitioners open every day, walked section by section: where answers land, where assets live, and how work gets shared.

Portal Administration
The half of the sidebar your admins hold: personas, connections, tool inspection, index health, and the audit trail behind every call.

Email Notifications
Work happens in the portal, attention happens in an inbox. Shares, replies, mentions, and review-queue alerts reach people where they already are.

One Endpoint
Greater Than the Sum of Its Parts
Plexara does not just connect Trino, DataHub, and S3. It interweaves them. A query result carries catalog context. A catalog search reveals what is queryable. A storage object surfaces its lineage. Each service enriches the others at the protocol level, producing responses that no single system could generate alone.
This interweaving replaces the need to stitch together five separate tools: catalog, semantic layer, query engine, observability, and governance. The result is not just fewer moving parts. It is a single MCP endpoint where query execution, business context, and governance enforcement are inseparable.
Under the hood
For the people who will ask how it works
Architecture
The middleware pipeline, the provider abstractions, and where enforcement happens.
Developer Hub
The MCP and REST surfaces, the test utilities, and the API reference.
Research
Open, reproducible benchmarks of what the platform changes about an agent.
Changelog
A weekly, plain-language record of what has landed in your deployment.
Common questions
Plexara Product FAQ
Any client that speaks the Model Context Protocol. That includes Claude Desktop, ChatGPT, the Anthropic and OpenAI SDKs, Cursor, Continue, and custom agents you build in-house. Plexara is the server; the client is your choice.
Plexara is a managed deployment operated by Deasil Works on infrastructure we run across six US data center facilities. AI agents reach Plexara over the standard MCP transport. There is no SaaS marketplace tier and nothing to install on your laptop.
Learn more: Our data center locationsYes. The Trino federation layer routes a single SQL query across 40+ connectors, including PostgreSQL, Iceberg, Snowflake, S3, Kafka, and Elastic. Agents write standard SQL without knowing where the data physically lives.
Learn more: Trino Query: analytics and insightsPersona-based access control restricts which tools and which data an agent can see, mapped to your existing identity provider. Default-deny applies to anything not explicitly allowed. Every tool call is logged with user identity, persona, and result so sensitive-data access is auditable end to end.
Learn more: Closed by default: least privilege as the starting pointYes. Plexara exposes a REST API covering assets, collections, knowledge, memory, prompts, personas, audit, governance, and tool execution, so non-MCP systems can integrate the same governed surface. The MCP server and the REST API share one identity, audit, and persona model.
