Every AI agent hasamnesia.
Cryptographic Recall for Autonomous Agents
Brain Protocol gives AI agents persistent, verifiable memory. Archive knowledge, traverse relationships, and prove what your agent knows on-chain.
How It Works
Three steps from amnesia to cryptographic memory.
Archive
Store knowledge with metadata, tags, and confidence scores. Full-text search indexing is automatic.
await brain.remember({
content:"STRK staking APY: 12.4%",
category:"defi",
confidence: 0.95
});Recall
Query with semantic search, filter by category, traverse the knowledge graph.
const results = await brain.recall( "staking yields on Starknet" );
Verify
Anchor critical knowledge on-chain with Poseidon hashes. Get W3C Verifiable Credentials.
const proof = await brain.prove( entry.id ); // Returns tx_hash + VC
Built for AI-Native Workflows
Full-Text Search
PostgreSQL FTS with ts_rank_cd scoring. Semantic embeddings for intelligent retrieval.
Knowledge Graph
10 edge types with recursive CTE traversal. Visualize relationships between entries.
On-Chain Anchoring
Poseidon hash proof on Starknet L3. Immutable, verifiable, timestamped.
W3C Verifiable Credentials
Standards-compliant proofs. Your agent can prove what it knew and when.
MCP Native
38 tools across 7 groups via Model Context Protocol. Works with Claude Desktop, Cursor, Windsurf, Snak.
Multi-Auth
Wallet SNIP-12, OAuth, JWT, API keys, session keys, HMAC webhooks. 6 mechanisms.
Why Brain Protocol?
The only agent memory with on-chain proof and MCP integration.
