Open-source AI context firewall for governed model, retrieval, memory, and tool access. It enables OpenAI SDK applications to adopt governed access via a single base_url change and includes MCP support.
Policy-enforcing MCP proxy that blocks dangerous tool calls before they execute. Protects credentials, filesystem, shell, and databases across Claude Desktop, Cursor, Windsurf, and OpenClaw.
mcpwall is a deterministic security proxy for MCP tool calls — iptables for MCP.
It sits between the MCP client and server, intercepting every JSON-RPC request and enforcing YAML-defined policies.
