A least-privilege enforcement proxy for MCP servers. It sits between MCP clients and upstream servers, enforcing tool policies, hiding denied tools, requiring human approval for risky actions, and providing a structured audit trail.
Security gateway that wraps any MCP server with per-tool policies, approval gates, and optional Ed25519-signed decision receipts. Shadow mode logs every tool call without blocking; enforce mode applies block, rate-limit, and minimum-tier rules. Receipts are independently verifiable offline with no accounts needed.
Enforces fine-grained, context-aware access control on MCP tool calls, with a tamper-evident, replayable audit log that records denials and verifies every decision.
