io.github.Ansarii/zero-trust-gateway MCP Server

This MCP server implements a zero-trust gateway for connecting Claude Desktop or custom AI agents to internal Enterprise databases (Postgres) and Knowledge Bases (Notion). It secures access by using an API key firewall and supports safer database interaction via enforced read-only query execution.

🛠️ Key Features

Zero-trust Postgres with remote SQL queries forced into READ-ONLY transaction blocks
Restricts agent actions to prevent dropping tables or deleting data
Notion Enterprise Search for secure internal wiki and document searching
Audit Logging & routing for MCP traffic

🚀 Use Cases

Securely query internal Postgres databases from Claude and AI agents without exposing root credentials
Enable Claude to search internal Notion Enterprise knowledge bases and documents

⚡ Developer Benefits

Reduced risk of data destruction by constraining SQL to READ-ONLY transaction blocks
Audit logging and routing of MCP traffic for observability

⚠️ Limitations

Focused on securing internal Enterprise database (Postgres) access and Notion Enterprise search; no other tool categories are described in the provided data

Features

Zero-Trust Postgres: Execute remote SQL queries forced into READ-ONLY transaction blocks. Agents cannot drop tables or delete data.

Notion Enterprise Search: Let Claude search your internal wikis and documents securely.

Audit Logging & Routing: All MCP traffic is routed through a secure Python Gateway.
