Pipelock
Open-source agent firewall securing MCP, HTTP, and WebSocket traffic with signed, verifiable evidence.
Pipelock is a serious, battle-tested option for teams that want flat-priced agent firewall protection with verifiable audit trails. Its signed receipts and compliance mappings are genuinely distinctive, but the CLI-heavy setup and self-hosting requirement will only appeal to security engineers. If you need a fully managed SaaS with zero ops, look elsewhere.

About Pipelock
Pipelock is an open-source agent firewall that mediates all MCP, HTTP, and WebSocket traffic at the agent boundary. It protects coding agents like Claude Code, Cursor, VS Code, JetBrains, and Zed, as well as any AI agent that speaks HTTP or WebSocket. You install it as a single Go binary and can wrap a local stdio MCP server with the same 11-layer scanner pipeline used for network upstreams. The core engine is free under Apache 2.0, with flat-rate paid plans for coordination and enterprise governance. Detection runs through an 11-layer scanner pipeline that catches 65 DLP credential patterns with checksum validation and 34 prompt-injection patterns using 6-pass normalization to handle zero-width characters, homoglyphs, and leetspeak. MCP-specific protections include tool poisoning detection, rug-pull tracking, session binding, and a policy engine with warn, block, redirect, or defer actions. Enforcement is adaptive with three escalation levels and a fail-closed kill switch triggered from six independent sources, plus kernel-enforced egress containment via nftables and a process sandbox using Landlock and seccomp on Linux. Beyond blocking, Pipelock emits Ed25519-signed action receipts that any third party can verify offline using free verifier libraries in Go, TypeScript, Rust, and Python. It maps compliance evidence to seven frameworks: OWASP MCP Top 10, OWASP Agentic Top 10, MITRE ATLAS, EU AI Act, NIST AI RMF, HIPAA, and SOC 2. The v3.4 release tightens MCP trust policy and scans media request bodies, while v3.3 added subject-keyed denial-of-wallet budgets, encoded-egress detection, opt-in audit-queue encryption, and SNI-required CONNECT. The v3.1 release introduced an operator dashboard and a free evidence viewer. Where Pipelock differs from vendor-specific MCP gateways is its open-source auditability, flat pricing that doesn't scale with agent count, and the signed evidence it produces for compliance. It's built for security engineers and teams running AI agents who need runtime guardrails and proof of enforcement.
Behind the Verdict
Pipelock stands out in the agent firewall space for its open-source core (Apache 2.0) and its focus on verifiable evidence. Unlike many vendor-specific gateways, it sits at the agent boundary and handles MCP, HTTP, and WebSocket traffic uniformly, so it works across a wide range of agents and frameworks. The 11-layer scanner pipeline with 65 DLP patterns and 34 injection patterns is deep, and the 6-pass normalization is a serious attempt to defeat obfuscation. The kill switch with six independent sources and fail-closed defaults gives you real control in an incident. Where Pipelock really shines is in compliance. The Ed25519-signed receipts are verifiable offline by anyone, and the mapping to seven frameworks (OWASP, MITRE, EU AI Act, NIST, HIPAA, SOC 2) is rare. This makes it a strong choice for regulated industries or anyone who needs to prove to auditors that their agents are being monitored. The downsides are real: it's a CLI tool, so you'll need command-line comfort to install and configure it. The free Community tier is limited to one profile, so teams with multiple agents will need to pay. And while the pricing is flat (no per-seat or per-request meter), the $25k/year Enterprise tier might be steep for small shops. If you want a fully managed SaaS with a GUI, this isn't it. Overall, Pipelock is a fit for security-conscious engineering teams that are already running coding agents and want a self-hosted, auditable firewall. It's less ideal for non-technical users or those who want zero ops.

Real-world workflow fit
Concrete scenarios for the personas Pipelock actually fits — and what changes day-one when you adopt it.
You need to protect Claude Code from leaking API keys. You install Pipelock, run `pipelock claude setup`, and it configures the proxy automatically. You then create a security profile with DLP patterns and test it in the playground. Within 30 minutes, you see blocked attempts in the dashboard.
Outcome: You have real-time visibility into agent egress, with signed receipts proving that exfiltration attempts were blocked.
You need evidence that your AI agents comply with HIPAA. You run `pipelock assess` to generate a signed security assessment, and you use the compliance mapping to map your controls to HIPAA requirements.
Outcome: You get a verifiable, offline-checkable audit report that you can present to auditors.
You manage hundreds of agents across teams. You purchase the Enterprise plan and use Conductor to push signed policy bundles to all followers, enforce a kill switch, and aggregate audit trails.
Outcome: You have central governance over all agent traffic, with one-command rollback and emergency kill capabilities.
Use Cases
- Block credential leaks from Claude Code by scanning outgoing traffic for API keys and tokens
- Enforce MCP tool policies to prevent tool poisoning attacks in agent workflows
- Generate signed audit reports for SOC 2 compliance during agent runtime assessments
- Deploy process sandboxing to contain agent subprocesses on Linux and macOS
- Use the kill switch to instantly deny all egress when a prompt injection is detected
- Run pipelock assess to get a signed security assessment for compliance evidence
- Set subject-keyed denial-of-wallet budgets to cap spend per agent
- Detect encoded egress attempts that hide data in encoding chains
Limitations
- Pipelock is an open-source agent firewall distributed as a CLI tool, requiring command-line proficiency for installation and configuration.
- The free Community tier is limited to a single default security profile, while paid plans add multi-agent coordination and enterprise features for central governance.
- The tool offers signed, verifiable evidence receipts and supports MCP, HTTP, and WebSocket traffic mediation, but TLS interception requires trusting Pipelock with your traffic.
- An operator dashboard is available in recent versions, yet the primary interface remains CLI and API.

Setup time & first value
How long it actually takes to get something useful out of Pipelock — broken out by persona, not the marketing-page minute.
For a single agent like Claude Code, you can be up and running in under two minutes: install the Go binary and run `pipelock claude setup`. Wrapping a stdio MCP server takes a minute. Setting up multiple profiles in Pro takes about 30 minutes. Enterprise fleet onboarding with Conductor may take a few hours to define policies and enroll followers.
Switching to or from Pipelock
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From an existing proxy: Install Pipelock and reconfigure your agent to point to the Pipelock proxy, then import your allowlists and rules.
- →From a vendor-specific gateway: Use Pipelock's universal MCP and HTTP support to replace the gateway with a single, auditable boundary.
- →From manual inspection: Start with the free Community tier and set up Pipelock as a sidecar to log and block, then gradually tighten policies.
- ↗To a managed gateway: Export your signed receipts and use them as evidence of your security posture during the transition.
- ↗To a different self-hosted solution: Pipelock's open-source core and rule bundles make it easy to replicate your policies elsewhere.
- ↗To a cloud-native WAF: You'll need to rebuild your detection rules, as Pipelock's agent-specific patterns won't map directly.
