"Memory" matching MCP servers:

Enables AI assistants to keep and retrieve private context locally, with verifiable receipts and optional Solana anchoring for public proofs.

Provides a persistent memory layer for Stellar and Soroban projects, scanning repositories to create a knowledge graph of contracts, storage, and on-chain state. Exposes this memory to AI agents via MCP, enabling project overview, search, and context recovery.

MCP server for wallet-addressed encrypted data storage and retrieval, enabling agents to receive paid messages and maintain checkpoints with E2E encryption.

Read-only access to the live NOVAI blockchain (an AI-native L1) over public JSON-RPC. Query blocks, transactions, AI entities, on-chain signals, oracle anchors, and memory objects. No keys, no write paths.

Stamp and verify Bitcoin-anchored OpenTimestamps memory receipts for AI agents (stamp_memory / verify_receipt).

An in-memory security MCP server for AI agents and coding copilots that prevents sensitive tool parameters and API keys from leaking into LLM context windows. Isolates execution arguments in local RAM using ephemeral cryptographic commitments and deterministic memory zeroization.

MCP server for the Computeback agent rewards marketplace and CB Hire B2B labor marketplace. Agents browse the storefront (compute, voice, memory, storage, 25+ categories) using $NOMD tokens, and discover/accept paid B2B work (email/voice/SMS/landing-page campaigns) and/or book travel on Autonomad for $NOMD earnings on Base L2.

Enables AI assistants to retain persistent, searchable memory and versioned vaults, spawn and recall named agents with state and audit history, run automations, monitors, and deep research, and execute on-chain and web tasks across sessions. It can be installed alongside Claude Code, Cursor, Windsurf, Zed, Hermes, and other MCP clients, with vault and memory optionally run entirely on the user's machine.

The whole Wicked suite for agents in one MCP server: 107 tools across trading data, prediction markets, web search, crypto news, wallet portfolio, DeFi and token risk, SEC filings, agent identity, reputation, a tool registry, hallucination checks, memory and x402 paywalls. No signup; pay per call in USDC on Base.

Cross-model, cryptographically verifiable memory for AI agents, enabling portable, encrypted memory and project state management across different LLMs through the Model Context Protocol.

Provides enterprise tools for Posthuman blockchain validators, South Asian demography operations (bKash, Steadfast, NBR VAT), episodic semantic memory, and isolated sandbox code execution via MCP.

Identity + memory layer for AI agents on the Emercoin blockchain — read open, write via GitHub OAuth

Connects Claude and ChatGPT to a marketplace of AI specialist packages, letting assistants discover and purchase on-chain licenses, activate them, then run each package's method step by step. It also exposes knowledge-base search, templates, persistent memory, tool execution, and deliverable submission with sandbox verification.

Persistent memory graph, knowledge marketplace, and MCP tool gateway for autonomous AI agents. Agents store experiences, trade knowledge via micropayments, and discover capabilities across the Hive network.

Provides on-chain identity and memory tools for AI agents, enabling them to register identities and store/retrieve memories on the Emercoin blockchain without holding cryptocurrency.

An AI-powered financial officer that makes autonomous trading decisions, provides strategic insights and risk management for the Mother Haven ecosystem. Integrates with trading bots and DEX platforms through MCP capabilities while maintaining personality and memory through git-first persistence.

Crypto-aware project memory for AI coding agents. Typed entities for Solana Programs/PDAs and EVM Contracts across Base, Optimism, Polygon, Arbitrum, Ethereum — plus chain-agnostic Decisions, Findings, and Integrations. Anchor + Hardhat auto-ingest, SQLite + FTS5 BM25 ranking, append-only versioning, git-aware diffs.

Enables AI agents to interact with the AI Network blockchain by managing accounts, submitting transactions, and reading database values. It supports registering Hyper Agents and accessing a Layer 2 DAG-based shared agent memory system based on staking status.

A permanent memory layer that enables AI agents to mint media and text as encrypted NFTs on the Polygon blockchain with IPFS storage. It provides tools for managing digital 'moments' with customizable privacy levels and secure access control via the Lit Protocol.

Enables LLM agents to search, navigate, and filter PolyMarket prediction market events with smart tools for data exploration. Features in-memory caching and background updates for instant queries across markets, liquidity, and analytics.
