The short version
Pipelock is a Go proxy that scans both HTTP and MCP traffic. It covers DLP, prompt injection, SSRF, tool poisoning, rug-pull detection, and data budgets across all agent network activity.
Agent Wall is a TypeScript MCP gateway focused on tool call control. It includes chain-of-command visualization (which agent called which tool through which chain), a kill switch for stopping compromised agents, and a dashboard for monitoring MCP activity.
Pipelock is broader (HTTP + MCP). Agent Wall is more focused (MCP only) but has features Pipelock doesn’t, like the dashboard and chain-of-command visualization.

Where Agent Wall is better
Dashboard. Agent Wall ships with a web UI that shows which tools are being called, by which agents, in what order. Pipelock exposes Prometheus metrics and a JSON stats endpoint, but doesn’t have a visual dashboard. If you need visibility into MCP activity without setting up Grafana, Agent Wall gives you that out of the box.
Chain-of-command visualization. In multi-agent setups, Agent Wall tracks which agent initiated a tool call chain. If Agent A calls Agent B which calls Tool C, you can see the full chain. Pipelock doesn’t track call chains across agents.
Kill switch. Both have kill switches. Agent Wall can shut down a compromised agent’s MCP access immediately. Pipelock has an OR-composed kill switch with four independent sources (config, API, SIGUSR1, sentinel file) — any one active blocks all traffic.
Where Pipelock is better
HTTP traffic coverage. Most agents don’t just call MCP tools. They fetch URLs, make API calls, and download content. Pipelock scans all of that. Agent Wall only covers MCP, so any HTTP-based credential leak or injection bypasses it entirely.
DLP depth. Both tools scan for secrets, but at different depths. Pipelock scans outbound URLs, headers, and request bodies for 46 credential patterns with base64, hex, and URL-encoding awareness. Agent Wall scans MCP responses for 14 secret patterns and 5 PII patterns. Pipelock also catches secrets in outbound requests (the exfiltration path), not just responses.
Prompt injection detection. Both tools detect injection patterns now. Pipelock scans HTTP responses and MCP tool outputs. Agent Wall scans MCP tool calls with 30+ injection patterns. Pipelock additionally scans fetched web content (HTTP responses), which Agent Wall can’t see since it doesn’t proxy HTTP.
SSRF protection. Pipelock blocks requests to private IPs, cloud metadata endpoints, and link-local addresses with DNS rebinding protection. Not in Agent Wall’s scope since it doesn’t proxy HTTP.
Process containment. Pipelock wraps any process with Landlock, seccomp, and network namespace isolation on Linux, and sandbox-exec profiles on macOS (alpha). Agent Wall doesn’t do OS-level containment.
Maturity. Pipelock has 8,800+ tests with race detection and 88% coverage. It’s been through multiple security hardening rounds including external pen testing. Agent Wall is newer (created February 2026). That doesn’t mean it’s bad. It means it hasn’t been battle-tested yet.
Architecture difference
The core difference is scope.
Agent Wall is an MCP gateway. It sits between agents and MCP servers, controlling which tools can be called and tracking the call chain.
Agent → Agent Wall → MCP Server
Pipelock is an agent firewall. It sits between the agent and all external communication, scanning HTTP, MCP, and WebSocket traffic.
Agent → Pipelock → Internet (HTTP)
Agent → Pipelock → MCP Servers (stdio/HTTP/WebSocket)
Agent → Pipelock → WebSocket endpoints
If your agent only talks to MCP servers, Agent Wall covers your use case. If your agent also fetches URLs, makes API calls, or connects to WebSockets, you need something that covers HTTP too.
When to use each
Use Agent Wall if: You want a dashboard for MCP tool activity, your agents only interact through MCP (no HTTP), and you want the kill switch capability.
Use Pipelock if: Your agents make HTTP requests in addition to MCP calls, you need DLP for credential leak prevention, or you need SSRF protection.
Use both if: You want Agent Wall’s dashboard and chain tracking for MCP visibility, plus Pipelock for HTTP scanning and DLP. They can coexist since they operate at different layers.
