"Understanding how memory is stored or memory storage methods" matching MCP servers:

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.

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

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

A Model Context Protocol tool that provides weather information for cities, with London access requiring Solana devnet payment via the Latinum Wallet MCP server.

Provides AI agents with seamless access to Filecoin's decentralized storage network for persistent file storage and dataset management. It features automatic payment handling, CDN support, and cost estimation tools for efficient storage operations.

Blockchain JSON-RPC on 23 EVM chains for AI agents — Ethereum, Base, Arbitrum, plus young chains like Robinhood Chain, Plasma and Ink. Free reads with no key; heavy methods (eth_getLogs, trace, debug) via a free API key or x402 USDC pay-per-call.

A curriculum that teaches AI agents how to spend their own money. Sixteen lessons from "what is a wallet" to your first x402 purchase. Teacher, not butler — never signs, pays, or holds keys.

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 Claude to interact with NEAR smart contracts: read state, call view methods, decode transactions, and explain contract interfaces.

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.

A simple MCP server implementation that provides AI models with basic Solana RPC methods and helpful development prompts.

Blockchain RPC via DRPC. Exposes eth_call, eth_getBalance, gas estimation, and other JSON-RPC methods as MCP tools across 100+ blockchains

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

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.

Enables ChatGPT and Codex to request public keys, prepare and sign exact Nostr events, encrypt or decrypt NIP-04/NIP-44 payloads, and publish with per-relay acknowledgement, while the private key stays in the user's Alby, nos2x, or remote NIP-46 signer. Every operation is queued for local browser approval, with one-use signing intents and verification before anything is broadcast.

Gives an AI agent a Stellar wallet for x402 payments whose spending budget is installed and enforced on-chain by a Soroban smart contract, so overspending is refused by the contract even if the agent process is compromised, replaced, or restarted. Budgets are declared as scoped, non-rounding data (e.g. 5 USDC per rolling day) that the agent can spend against but cannot alter or redirect.

mcp server that allows to do actual actions related to solana first version adds knowledge about RPC methods and how to call them

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.
