[ SENTNELOPS // MCP FIREWALL — SYSTEM ONLINE ]
Your agents move at
machine speed.
So does your firewall.
SentnelOps sits between your AI agents and everything they touch — intercepting every MCP tool call, weighing it against your policy, and blocking the ones that should never happen. In milliseconds. With a full audit trail.
DESCEND
[ SIGNAL // THE DARKNESS BETWEEN ]
When the auditor asks “what did your agents do?”
— what do you answer?
AI agents now open pull requests, run queries, and touch cloud infrastructure on their own. Every one of those actions travels over MCP — and almost nobody is watching the wire.
0
⟨ VISIBILITY ⟩
Tool calls your agents made last night that you can currently see, log, or replay. The dark is total.
1
⟨ TOOL CALL ⟩
That's all it takes. One unseen delete_repository, one rogue ec2_terminate_instance, and production is a memory.
∞
⟨ BLAST RADIUS ⟩
An ungoverned agent with production credentials has no ceiling. Autonomy without enforcement is just hope.
[ PROTOCOL // HOW THE SHIELD WORKS ]
Three moves. Total control.
PHASE 01
INTERCEPT
Point your agents at the SentnelOps proxy instead of your MCP servers. One config line. Every tool call now passes through the wire we watch.
PHASE 02
DECIDE
Each call is weighed against your YAML policy in milliseconds — by agent, server, tool, and environment. Permit, alert, or block. Deterministic. No model in the loop.
PHASE 03
ENFORCE
Dangerous calls die at the perimeter. Suspicious ones page a human. Everything — permitted or not — lands in an immutable, audit-ready log.

[ ARSENAL // CAPABILITIES ]
Everything you need to govern the swarm
Live intercept feed
Watch every agent → server → tool call stream across the wire in real time, with verdicts and latency for each one.
YAML policy engine
Declarative rules by agent, server, tool, and environment. Version them in git. Deterministic decisions — no model in the loop.
Instant alerting
Slack and email alerts the moment something is blocked or suspicious. Your on-call knows before the agent retries.
Audit-ready logs
Every call recorded with full context — exportable for SOC 2 evidence. When the auditor asks, you have the tape.
Millisecond overhead
Single-digit-millisecond decisions on the hot path. Your agents never feel the shield that protects them.
Team command deck
Multi-user dashboard with role-based access, plus a REST API and SIEM integration to feed your existing stack.
[ COMMAND DECK // MISSION CONTROL ]
One screen. Every agent. Every move.

The command deck streams verdicts as they happen — filterable by agent, server, tool, and outcome — and exports the whole record when compliance comes calling.
[ PERIMETER // TRUST PROTOCOLS ]
A firewall you can actually trust
We see metadata, not payloads
Policy decisions run on call metadata. Your prompts, code, and data never need to leave your perimeter.
Fail-safe by design
If SentnelOps ever goes dark, you choose the posture — fail closed and hold the line, or fail open and keep shipping.
Policies as code
YAML in your repo, reviewed like any other change. No console-only configuration that drifts in the night.
Built for your stack
REST API, SIEM export, Slack alerts. SentnelOps feeds the tools your security team already lives in.
[ FINAL TRANSMISSION ]
The agents are already inside the perimeter.
The only question is whether you can see them. Join the beta and put an enforcement layer between your AI and everything it can touch — before the next tool call is the one that matters.
