VerifiedState Memory

This server gives Claude a cryptographically signed memory layer across sessions. Instead of losing context when a conversation ends, it persists assertions that can be verified later, useful when you need audit trails or want to prove what was agreed upon in previous interactions. The billing attestation feature lets you track and verify API usage across sessions. You'd reach for this when building agent workflows that span multiple conversations and need verifiable state, like approval chains, multi-step research tasks, or any scenario where you need to prove what the AI remembered or committed to. Uses streamable HTTP transport and runs as a hosted service at mcp.verifiedstate.ai.
