Project Heimdall MCP Server

Example Use Cases

• 1

  Safely query PostgreSQL databases without risking data modification.

• 2

  Explore database schemas and retrieve data securely via MCP.

• 3

  That require a high-performance, secure middleware enforcing read-only SQL access.

Description

Project Heimdall is a Golang-based Model Context Protocol (MCP) server acting as a gatekeeper between AI clients and PostgreSQL databases. It uses an Abstract Syntax Tree (AST) parser to strictly enforce read-only SELECT queries, blocking any data modification attempts. This ensures high security by preventing destructive SQL commands while enabling LLMs to explore and query database schemas safely. The server integrates natively with the Anthropic ecosystem and is optimized for high concurrency and performance.
