Text-to-SQL for Agents

Give agents full access to your SQL database without the worry

Catch-Phrase gives agents controlled, hallucination-free natural language access to databases. So either you or your agent can ask questions or issue updates over the database and have confidence that the answers and operations are correct.

Accurate


100% Accuracy Guarantee

For questions and commands within the semantically tractable class

Verified Results

Always signals when a question or command is interpreted flawlessly (i.e. it is semantically tractable)

Read this paper for a description of the semantically tractable class and how accuracy is guaranteed.

Integrity Checking and Task Surfacing

Question sets that run in batch to reliably identify data integrity problems or queue work tasks

Zero SQL errors over agent or human executed question sets.

Intelligent Fallback

Candidate LLM prompts generated when a question or command is not semantically tractable.

No silent failures, no undetected hallucinations.
Controllable

Transparent, precise,
fully under your control

Every result is explainable. Every behaviour is configurable.

Agent-based

MCP Servers accept natural language questions or commands and return lists, tables, values, confirmation messages, suggested follow-up prompts, confirmations for modifications, etc.

Fully Configurable

can be configured for practically any specific semantic layer, data idiosyncrasy or permissions setup.

Comprehensive documentation covers all configuration options and deployment patterns.

Guarded Access

No uncontrolled evaluation of arbitrary SQL over databases. No need to open database ports for remote access.

Open

Designed to fit anywhere

Integrates with your existing stack in minutes, not months.

Deployable as an MCP Server based 100% on SQL and open XML and JSON formats.
