"Cursor Not Losing Memory or State" matching MCP servers:

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.

A read-only MCP server for safely exploring Nostr, enabling agents to resolve identifiers, fetch profiles and events, query notes, and inspect relay metadata. It does not accept private keys or publish events.

Enables interaction with the Cork DeFi protocol for reading live chain state, computing bit-exact math, building unsigned bundles and orders, and managing markets, all without signing or broadcasting.

Enables MCP clients to send cryptographically signed messages to Technocore mailboxes and KV state stores as native tools, with automatic did:key signing and atomic state locking.

Hashlock Markets — sealed-bid intent-based crypto trading via MCP for AI agents. Atomic cross-chain settlement (Ethereum, Bitcoin, Sui) using HTLC. Six MCP tools for RFQ price discovery without information leakage and HTLC settlement without escrow or bridges. Canonical npm: @hashlock-tech/mcp.

WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

MCP server for local transaction signing across EVM, UTXO, Tron, and XRP blockchains, with no network calls or API keys required.

Enables cross-chain swap execution across 12 venues and 17 chains, including native Bitcoin as source or destination, with tools for quoting, execution, status, and health checks. No signup, API key, or protocol fee required.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

Enables AI agents to interact with a Liquid network wallet, including balance checks, transaction history, and sending L-BTC or Liquid assets. Backed by an in-process LWK wallet, requiring only a mnemonic, with both stdio and HTTP support.

MCP server for defining, validating, deploying, and operating Shodai machine-readable agreements with EIP-712 permit preparation, signed participant inputs, state reads, and input history.

Thin MCP wrapper around the SQD Portal API for blockchain data queries across multiple networks including EVM, Solana, Bitcoin, Substrate, and Hyperliquid. Provides 25 public tools for discovery, cross-chain queries, and chain-specific operations.

A self-hosted decision engine that sits between an AI agent and blockchain execution. Agents submit a proposed action, Guardian returns an explainable ALLOW / WARN / BLOCK before anything gets signed or broadcast.

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.

Provides access to 70 paid APIs as MCP tools with per-call and session budgets, paying via x402/USDC on Base without requiring an account or login. Includes a built-in allowlist of hosts and safe defaults to prevent unintended payments.

Hashlock Markets (hashlock.markets) — sealed-bid intent-based crypto trading protocol with HTLC atomic settlement. AI agents can create, commit, and validate trading intents on Ethereum, Bitcoin, and Sui. Canonical npm package: @hashlock-tech/mcp. Not the cryptographic hashlock primitive, not Hashlock Pty Ltd (hashlock.com).

Enables AI agents to obtain non-custodial Solana-to-Base quotes, verify signed manifests and status, and prepare or verify unsigned execution plans without handling private keys or submitting transactions.

Enables an agent to fetch the material a separate verifier checks — receipts, genesis documents, univocity accumulator snapshots, registration statuses and SCITT service configurations — from a SCRAPI base URL or a chain RPC endpoint you supply. Every result reports where its bytes came from and which trust-model questions they can answer, without ever choosing an operator or chain provider for you.
