Protocol

Every MCP Client. One Verified Memory Layer.

Your MCP agents store facts across sessions. VerifiedState makes those facts provable.

The Problem

MCP gives agents tools. It doesn't give them memory. Between sessions, everything resets. Agents re-learn. Users repeat themselves. When something goes wrong, there's no record of what the agent believed.

Memory flows between MCP clients. Receipts prove it.

• • • Claude Desktop
> Remember: deploy target is us-east-1
✓ Stored · rct_d41a · 0.95
• • • Cursor
> Where do we deploy?
✦ 1 verified assertion
us-east-1 — stored via Claude Desktop.
Receipt: rct_d41a

Two clients. One memory. Same receipt.

Step 3
Verify + Receipt

The Fix

No install needed — just add MCP server config:

json
{ "mcpServers": { "verifiedstate": { "url": "https://mcp.verifiedstate.ai/mcp", "headers": { "Authorization": "Bearer vs_live_..." } } } } // 23 tools available: // Memory: memory_ingest, memory_query, memory_verify, memory_health, memory_query_events, memory_subscribe // Meter: meter_authorize, meter_spend, meter_budget, meter_settle, meter_verify, meter_receipts // Session: session_save, session_load, session_list, session_delete, session_end // State: working_state_get, working_state_update // Alerts: alerts_get_unacknowledged, alerts_acknowledge, alerts_resolve // Teams: teams_list

What You Get Back

✓ VERIFIED
receipt.json
{ "receipt_id": "rct_7f3a...", "assertion": "User prefers dark mode", "status": "verified", "confidence": 0.94, "signature": "ed25519:a8c3f1...", "verified_at": "2026-04-06T14:32:01Z", "chain_position": 42 }
