VerifiedState

Decision trace infrastructure for AI agents. VerifiedState is a standalone verified memory layer — any AI agent, model, or workflow can write assertions to a shared memory store and receive cryptographic verification receipts in return. Every fact is signed with Ed25519, timestamped, confidence-scored, and queryable at any point in time. Built for regulated industries where "the agent said so" isn't good enough.

Connect via MCP

Any MCP-compatible client (Cursor, Claude Code, Windsurf, Goose) can connect in one step:

{
  "mcpServers": {
    "verifiedstate": {
      "url": "https://mcp.verifiedstate.ai/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY",
        "X-Namespace-ID": "YOUR_NAMESPACE_ID"
      }
    }
  }
}

Or use the CLI:

npx @verifiedstate/cli init

MCP Tools

Tool	Description
memory_ingest	Ingest raw content (conversation, document, user input) into verified memory. Creates an artifact and evidence spans.
memory_query	Semantic search over verified memory. Returns ranked assertions with their active receipts.
memory_verify	Run the verification ladder on an assertion. Produces a signed receipt and updates assertion status.
memory_health	Get memory health stats for a namespace: assertion counts, verification ratio, stale/expired, open conflicts.
meter_authorize	Create a Proof Meter capability that grants an agent a spend budget. Returns a signed capability token.
meter_spend	Record a spend event against a Proof Meter capability. Returns a signed, hash-chained receipt.
meter_budget	Check remaining budget and spend summary for a Proof Meter capability.
meter_settle	Settle outstanding spend receipts into a Merkle-rooted settlement batch.
meter_verify	Cryptographically verify a Proof Meter spend receipt (hash, signature, chain, Merkle inclusion).
meter_receipts	List and filter Proof Meter spend receipts for a namespace.
session_save	Save current session state — captures what was built, decisions made, files changed, and next steps.
session_load	Load the last saved session state for a project. Resume exactly where the last session ended.
