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.

{
"mcpServers": {
"verifiedstate": {
"url": "https://mcp.verifiedstate.ai/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_KEY",

}
}
}
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. |
