MCP security

Security for MCP tools and agents

The Model Context Protocol lets Claude, Cursor and other clients use real tools. Warden makes sure those tools cannot be turned against you.

Start free5-minute quickstart

MCP is powerful because it gives a model real capabilities: fetch, call, read, write. That is also the risk. RIL Warden ships an MCP server and sits in front of agent egress, so MCP-driven actions run through one policy engine with a full audit trail.

What Warden adds to MCP

Scoped egress per agent

Each MCP client/agent gets a default-deny allowlist. Tools can only reach what you approve.

Credentials the model never sees

Warden injects API keys server-side to the right host, so an MCP tool call cannot leak them.

Exfiltration + SSRF blocked

Tool calls to internal addresses or known exfil channels are refused.

Every tool call logged

A tamper-proof, signed record of each MCP action, for debugging and compliance.

Works with Claude, Cursor and more

Add Warden as an MCP server to your client, or route an agent's tool traffic through Warden's gateway. Either way you get containment and a flight recorder for everything the tools do. See the quickstart and integrations.

Frequently asked questions

Is MCP secure by default?
MCP defines how tools connect, not how to contain what they do. A tool can reach the network, touch secrets, and move data. RIL Warden adds the containment and audit layer MCP does not provide.
How do I secure an MCP server?
Put every MCP tool call behind a policy gateway: default-deny egress, server-side secret injection, exfiltration blocking, and a signed audit log. RIL Warden provides this and can itself run as an MCP server.
Does Warden work with Claude and Cursor?
Yes. Warden can be added as an MCP server to MCP clients like Claude and Cursor, or placed in front of their agents' egress.
Can I see every tool call an agent made?
Yes. Warden records each action in a hash-chained, signed, on-chain-checkpointed log.
