Verdict L402 MCP

An action firewall for AI agents that evaluates proposed actions against untrusted content to detect prompt injection, data exfiltration, and other security risks. It returns allow, review, or block decisions with scores and reasons, helping agents avoid expensive mistakes before executing commands, payments, or tool calls.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http verdict-l402-mcp https://verdict.kechlab.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add verdict-l402-mcp --url https://verdict.kechlab.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable verdict-l402-mcp in your MCP settings.
