"How to connect Cursor directly to a MongoDB database without losing state" matching MCP servers:

Enables risk-adjusted yield rankings and policy checks for DeFi research via a remote MCP endpoint.

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

Enables AI agents to construct SHA-256 Merkle trees and generate/verify inclusion proofs, validate JWT HMAC-SHA256 claims, run Schnorr zero-knowledge identification, and enforce constant-time secret comparison with nonce replay protection for tamper-evident state attestation. It runs as a zero-dependency, stdlib-only MCP stdio server for clients such as Claude Desktop, Cursor, and Windsurf.

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

Connects AI assistants to Solodit's 49,000+ blockchain vulnerability database, enabling search, browse, and lookup of audit findings directly from your AI workflow.

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.

Enables AI agents to query entities from Arkiv database chains using a SQL-like filter expression, with pagination and configurable fields.

A Model Context Protocol server for Lighter — a zero-fee zk-rollup perpetual DEX on Ethereum. Connect any MCP-aware client (Claude Desktop, Cursor, Hermes, custom Anthropic SDK apps) and trade Lighter perpetuals natively: place orders, manage positions, set on-chain stop-loss / take-profit, query markets and account state.

Enables AI agents to perform local session-state checks for TDM, helping decide whether to continue, fuel, sweep, or connect the wallet.

Connects a Bitcoin Lightning wallet to your LLM using Nostr Wallet Connect, enabling payment functionalities within language models like Claude.

Provides access to Mina blockchain data, enabling queries for events, actions, and network state information through a standardized interface.

Connects a Bitcoin Lightning wallet to your LLM using Nostr Wallet Connect, enabling payments and interactions with Lightning Network features.

Enables users to manage API keys and perform Aptos Build actions through MCP-compatible interfaces like Claude and Cursor. This server facilitates development workflows on the Aptos blockchain by integrating directly with the Aptos Build platform.

Connect any AI agent to Arcis Protocol DeFi vaults through natural language, enabling deposit, withdrawal, and status queries without SDK or code.

A read-only Model Context Protocol server for Hyperliquid that exposes over 30 tools to query public market data and user state via the Hyperliquid Info API, without requiring a private key.

Enables to simulate EVM transactions (dry-run) to preview results, gas usage, and state changes before broadcasting on supported blockchains.

Enables AI agents to interact with the Casper blockchain through MCP tools for reading node state, inspecting blocks, querying global state, and evaluating treasury policies. Includes a Treasury Guard reference agent that autonomously enforces DeFi treasury policies on Casper Testnet.

MCP server for temporal state queries and cryptographic audit trails. Query historical entity state at any point in time, generate Merkle proofs of past state, and anchor contract snapshots for immutable provenance.

This repository is the public manifest for the hosted Vibe Springs MCP server. The server runs at https://vibesprings.net/mcp — there is nothing to install or build. Connect directly over Streamable HTTP. 🌐 Endpoint: https://vibesprings.net/mcp (Streamable HTTP, stateless) 🧰 22 tools — 2 free, 20 pay-per-call 💸 Payment: x402 on Base mainnet (USDC), signed per call by the agent's own wallet 📖

A Model Context Protocol server that enables Claude to interact directly with IPFS for content-addressed storage, peer-to-peer networking, and decentralized data management.
