"Adding a remote MCP server to Claude Desktop using HTTP+SSE" matching MCP servers:

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

A Model Context Protocol (MCP) server that provides tools and resources for AI agents to interact with the Algorand blockchain.

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.

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

Enables users to audit EVM, Solana, and Move smart contracts and assess Web3 security risks through tools for honeypot detection, SPL token risk, MEV sandwich exposure, address poisoning, HTTP 402 invoice fraud, UTXO consolidation planning, and cross-chain bridge quotes.

Market-timing bottom/top signals for ten markets — crypto, US/Korea/China/Hong Kong stocks, commodities, FX, inflation and Seoul/Dubai property — returning a verdict and a -100..+100 score per symbol plus market-wide bottom/top scans. Ships a stdio proxy to the ten remote Streamable HTTP endpoints; the free pitch tool introduces each market's catalog.

An MCP wallet server that lets an AI agent hold, send, and spend USDC on Hedera, using the x402 standard for HTTP payments.

Enables Claude to analyse a Nostr relay read-only: reachability, NIP-11 details, recent and counted events, activity reports, author lookups, spam triage and event engagement, with third-party text fenced as untrusted. When explicitly enabled, it also lets Claude draft notes and reactions and publish them through a NIP-46 remote signer, with the user's key staying in the signer and every publication requiring human confirmation.

A Model Context Protocol server that enables interaction with Polymarket prediction markets through Claude Desktop.

Enables read and write interactions with 60+ blockchain networks through Claude Desktop, providing a standardized multi-chain API for transaction management, account insights, staking, and token interactions.

Provides enriched blockchain data from Codex for use with MCP-compatible clients like Claude Desktop.

Provides remote SSE-based computational infrastructure with 40+ deterministic tools, including free utilities like JSON repair and context trimming, plus pay-per-call web3 and network oracles for autonomous AI agents.

Enable AI assistants to interact directly with Bitcoin Ordinals inscriptions. Seamlessly integrates with Goose and Claude Desktop to retrieve and display inscription content from transactions.

Enables comprehensive interaction with the Zetrix blockchain including account operations, transactions, smart contracts, WebSocket real-time updates, and contract development tools through Claude Desktop.

An MCP server that allows querying MON token balances and NFT counts on the Monad testnet, enabling Claude Desktop to interact with the Monad blockchain.

Enables Claude Desktop to interact with the VeChain blockchain through natural language commands for token transfers, DEX trading, cross-chain bridges, NFT management, and VeBetter DAO operations.

A server that interfaces with the Hedera Testnet Mirror Node API, converting its OpenAPI-defined endpoints into MCP-compatible tools that can be accessed over Server-Sent Events (SSE).

Enables interaction with the Stacks blockchain through Claude Desktop. Manage wallets, trade tokens on DEXs, stack STX for Bitcoin rewards, and track portfolio—all through natural conversation.

Enables AI agents to access 28 monetized Web3 developer tools, including web scraping, PDF extraction, smart contract deployment, and cross-chain USDC micropayments via SSE and x402.

MCP server for building, auditing, and querying BitBadges collections via AI. Works with Claude Desktop and other MCP clients to generate transaction JSON for BitBadges tokens and collections (deprecated, use bitbadgesjs-sdk).
