Pylar
Pylar
Governed data access layer that lets AI agents query controlled SQL views and MCP tools without exposing raw databases.
Key features
- Governed SQL Views: Create and manage curated SQL views that expose only authorized subsets or transformations of underlying tables, preventing agents from accessing raw database rows or schemas directly.
- MCP Tool Publishing: Package governed views and query endpoints as MCP tools that can be published and deployed to any agent builder, simplifying distribution of controlled data capabilities to agents.
- Fine-Grained Access Control: Enforce policies and permissions at the view or tool level so different agents or agent roles can only run allowed queries and receive permitted fields.
- Secure Query Execution: Route agent queries through a managed execution layer that sanitizes inputs, applies limits and quotas, and prevents unauthorized SQL execution patterns.
- Auditing and Logging: Capture detailed logs of agent queries and access events for compliance, forensics, and monitoring of data usage by agents and tools.
- Database Integrations and Connectors: Connect to existing relational data stores and map schemas into governed views, enabling rapid adoption without migrating source data.
- Create governed SQL views for safe data access
- AI-powered MCP tool creation
- Connect 100+ business tools and databases
- Managed ingestion, ETL, and hosted warehouse
- Cross-database joins and multi-database integration
- Publish and deploy tools to any agent builder
- Built-in observability and control pane
- Create governed SQL views to expose controlled subsets of structured data to agents
- Build MCP-compatible tools that can be deployed into agent builders
- Deployable to any agent builder / agent framework (platform-agnostic integration)
- Secure, scalable access controls for agent-driven queries against databases
- Governance and policy enforcement for data access in agent workflows
- GitHub presence for project assets and workstation tooling (PylarAI organization)
Best for
- Safe Agent Access to CRM Data: Expose a limited, governed view of a customer database so conversational agents can answer customer-specific questions without full DB access or PII exposure.
- Publishable MCP Tools for Agent Platforms: Package analytics or lookup queries as MCP tools and deploy them to multiple agent builders so agents can access standardized data functions.
- Compliance-Focused Data Access: Maintain audit trails and enforce view-level permissions for regulated environments (finance, healthcare) where agent queries must be restricted and logged.
- Operational Dashboards for Agents: Provide agents with curated operational metrics and KPIs from production databases without risking query patterns that could impact performance or reveal sensitive schema.
- Multi-tenant SaaS Data Isolation: Create per-tenant governed views so agents serving different customers can query only their tenant data while using the same underlying infrastructure.
- Prototype and Test Agent Workflows: Rapidly define safe SQL views to let agents prototype data-driven workflows without waiting for heavy engineering changes or database refactors.
- Let AI agents query CRM, billing, and product data without direct DB access
- Build and deploy MCP tools for customer support or sales assistants
- Provide governed data access for agent-driven analytics and reporting
- Host synced business data in a managed warehouse for secure agent usage
- Provide AI/agent workflows safe, governed query access to enterprise SQL databases

Voicebox is a free, open-source, local-first AI voice studio for cloning voices, generating speech in 23 languages, and dictating anywhere.
Key features
- Voice Cloning: Clone a voice from a few seconds of audio and reuse it across generation and dictation.
- Multi-Engine TTS: Generate speech in 23 languages across 7 engines including Qwen3-TTS, Chatterbox, HumeAI TADA, and Kokoro.
- Global Dictation: Hold a customizable key chord anywhere to record, transcribe, and refine straight into any text field via an on-screen pill.
- Captures Tab: Every dictation, recording, and upload is preserved with its original audio paired to a transcript.
- MCP Agent Voice: Give any MCP-aware agent such as Claude Code or Cursor a voice of your choosing that speaks back through a pill.
- Local Processing: Runs Whisper transcription and a bundled local LLM on your machine via MLX or PyTorch, with a REST API for integration.
Best for
- Hands-Free Writing: Dictating into any app with a global hotkey instead of typing.
- Voiceover Production: Cloning and generating narration in multiple languages locally.
- Agent Voice Output: Giving coding agents a spoken voice for feedback.
