"Designing a memory system for persona-based agents to improve user experience" matching MCP servers:

A set of MCP servers that provide AI agents with safe, composable access to web3 market data and trading, featuring read-only intelligence and execution modes with SIM/PAPER/LIVE safeguards.

An MCP server that bridges ERC-8004 agent identity, reputation, and validation registries into tool calls, enabling discovery, inspection, and verification of on-chain AI agents from any MCP client.

23 tools for AI agents working with Nostr Open source. No API key. No account. NIP-46 remote signing Publish notes, reply, react, repost Encrypted DMs (NIP-04 + NIP-44) Fetch events, profiles, social graph

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Enables MCP clients to connect to Walrus Memory for persistent memory operations like remember, recall, analyze, and restore, with browser-based wallet login and local credential storage.

Enables MCP-compatible AI agents to save encrypted, DID-signed session checkpoints and resume the latest state across sessions, while keeping secrets and credentials in a local vault.

Exposes OriginTrail DKG V10 working, shared, and verifiable memory as standard MCP tools, enabling users to read, write, share, and query DKG memory from any MCP-capable client without custom HTTP wiring.

9 tools, Lightning-gated. Pay per call. For agents that need verifiable signed actions with an audit trail. Nostr event signing via daemon Publish events to relays Create Lightning invoices Action receipts — signed proof of agent actions Identity attestation

MCP server for Web3 AI agents enabling autonomous smart contract engineering on Robinhood EVM and Solana, with Cloudflare One portals for efficient token usage and edge execution.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Solana token risk-scoring MCP server for AI trading agents — 0-100 safety score, on-chain insider wallet cluster detection, mint/freeze authority checks, and historical risk data via 3 tools.

Enables users to compare current Aerodrome veNFT voting positions, bounded claimable rewards, and selected pools' voting evidence on Base against a saved local baseline, with retryable, atomically stored change reports. All tools are read-only on chain, requiring no keys, signing, or transactions.

A server that enables interaction with the Solana blockchain, providing access to over 40 Solana RPC methods including getting balances, transaction details, block information, and sending transactions.

Enables querying Base Network blockchain data including blocks, transactions, balances, and smart contracts on mainnet and testnet.

Enables LLM coding agents to sign in with Nostr by generating NIP-07 signatures and exposing public keys, without requiring a wallet or browser extension.

A remote MCP server that links World ID 4.0 sessions to AI assistants, enabling verified human authentication and tools for claiming Founding Human places, accessing human grants, and interacting with a verified human wall.

A Model Context Protocol server that enables Claude AI to interact with the Solana blockchain, allowing it to execute transactions, query accounts, manage wallets, get price predictions, trade tokens, and access various blockchain data sources.

An MCP server that provides real-time web search to AI agents via a pay-per-search USDC microtransaction system.

Provides tools for AI agents to access Bitcoin, Lightning Network, and Nostr knowledge, including real-time network statistics and Web of Trust reputation data. It features an integrated Lightning Network payment system for micro-transactions and query-based interactions.
