Security firewall for AI agents — intercept MCP tool calls, enforce policies, block attacks

Intercept MCP tool calls, enforce policies, block attacks. Zero-config protection for any MCP server. Inspects tool calls going IN and responses coming OUT. Blocks secrets, private keys, and PII before they reach the agent. Sensible built-in defaults block credential access, exfiltration, and dangerous shell commands out of the box. Works with every MCP server — official, third-party, or custom. Protocol-level proxy means zero code changes. Structured JSON logging of every tool call and response scan with sensitive value redaction. Full audit trail. Detects leaked API keys, tokens, private keys, database URLs, and PII in server responses. Block or redact automatically. Global and per-rule…from agent-wall.github.io

  • Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
