About Arun-kc/schemabrain

Schemabrain acts as a read-only intermediary between AI agents and databases, using a semantic knowledge graph to provide context and an audit log for transparency. It is built as an MCP-native tool in Python, enabling agents to query structured data without write access.

Best for

Developers building AI agents that need safe, contextual database access

Use cases

  • Querying databases with natural language through AI agents
  • Enforcing read-only access for agent interactions
  • Auditing agent queries with a semantic context layer

Notes

8 stars on GitHub. Last updated 2026-06-18. Licensed Apache-2.0.

Pros

  • Read-only architecture prevents accidental data modification
  • Semantic knowledge graph improves query accuracy
  • MCP-native design integrates with existing agent frameworks

Cons

  • Limited to read-only operations, no write support
  • Requires setup of semantic knowledge graph
  • Relatively new project with small community (8 stars)
