About Surfil
What is Surfil?
Surfil is an on-device control plane for AI coding agents. It sits beside tools like Claude Code, Cursor, Codex, and Copilot to monitor and control how they spend tokens, access data, and handle memory. Instead of promising fixed savings, Surfil measures your actual traffic and reports real numbers—every claim backed by a signed, offline-verifiable receipt.
Problem it solves
AI coding agents are expensive, risky, and forgetful. They re-send context, can leak credentials, and lose state across sessions. Surfil intercepts your agent traffic byte-exactly—so your prompt cache keeps hitting—and provides a single point to watch cost, enforce safety policies, and persist memory. It never sends your source code off-device and never meters your usage; you pay only for signed proof outputs.
Who is it for?
Surfil is for individual developers and teams who rely on AI coding agents daily and need measurable control. It's not for casual users—there's no free tier, and the setup assumes some familiarity with CLI tools and MCP. Ideal for those who want to verify savings, prevent credential leaks, and keep memory consistent across multiple agents.
Use cases
Consolidate multiple MCP servers into one endpoint, reduce redundant token spend, audit weekly recoverable spend with signed receipts, and run Guard to block outbound credential leakage. Team plans add dashboards and pooled credits for collaborative workflows.
Key features
- Core (install, consolidation, Weave) — Streamline MCP servers and reduce token overhead.
- Guard monitor/enforce + sandbox — Screen outbound traffic for credentials like API keys and block risky access.
- Cap full ledger — Track every token spent with a detailed, auditable ledger.
- Mind full + sync — Persistent memory that syncs across agents and sessions.
- Radar, Bench, Pilot — Advanced benchmarking and pilot features for optimizing agent performance.
- Signed receipts (Ed25519) — Verify any savings or safety claim offline, without an account.
- Byte-exact interception — Preserve prompt caching to keep costs low.
