"Servers that support Server-Sent Events (SSE)" matching MCP servers:

Enables creating and managing webhook subscriptions for blockchain events such as new blocks, confirmed transactions, and token transfers across major blockchains (EVM, UTXO, Solana, XRP).

Enables monitoring token launch liquidity pools, tracking whale wallet activity with USD-based alerts, and analyzing market sentiment across social, news, and on-chain sources.

An SSE (Server-Sent Events) server that leverages OKX DEX SDK to support DEX trading operations on Solana blockchain and cross-chain bridge transactions.

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).

Provides real-time information about Ethereum addresses across multiple chains using the Model Context Protocol, featuring a Server-Sent Events endpoint for live updates.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.

An MCP server that enables cross-chain token transfers via the Stargate protocol.

MCP server that enables AI signing agents to pre-flight transactions by checking ERC-7730 descriptor safety, explaining function semantics, and scanning contracts for danger primitives.

MCP server that builds unsigned Paraswap token swap transactions for self-custody wallets, holding no keys and signing nothing. It returns raw transaction data for a human to review and approve before execution.

MCP server that lets AI agents discover and pay for .agent services using USDC over x402, with daily budget controls and payment link creation.

AI travel agent over MCP — live flights, hotels, activities, and events worldwide, then completes the booking on autonomad.ai.

Live liquidity-pool scores for Solana + EVM: Enter/Hold/Exit verdicts and a composite 0-100 Wealthville Score, backed by a public, immutable track record that includes misses. Read-only, free, no key required. Data product, not financial advice.

Pre-trade safety for EVM, Solana and TRON: simulates a real buy and a real sell against live liquidity, so a honeypot shows as a sell that fails instead of a vendor score, and audits a wallet's standing approvals across the three chains. Python standard library only, no API key.

Deploys AI agents on-chain into the Metaplex Agent Registry on Solana, minting Core assets with EIP-8004 identity. Supports self-custodial signing via server keypair or external wallets, with devnet support for free rehearsal.

MCP server that preflights endpoints before agent payments, returning a trust verdict with proceed/caution/avoid recommendation.

Prediction-market MCP server for Kalshi and Polymarket: market search, live order books and quotes, each venue's fee schedule, fee-aware no-arbitrage checks across related event contracts, and paper orders that walk the book.

MCP server for Stellar that enables AI assistants to explain account holdings, diagnose transaction failures, and describe Soroban contracts in plain language, with optional payment proposal flow.

An MCP server that gives AI agents fast access to verified EVM chain information, including RPC URLs, chain IDs, explorers, and native tokens.

A read-only MCP server that exposes BaseZap's tipping-agent tools to any MCP client, allowing users to fetch platform info, compute USDC tip quotes, build unsigned ERC-20 transfer calldata, and resolve Farcaster usernames to wallet addresses.

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.

Local Ethereum wallet for AI agents — read balances and history, request payments that a human approves by password in the app popup, and fetch x402-paywalled resources with USDC on Base. Keys are encrypted on-device and never leave your Mac.

A read-only Model Context Protocol server for the Thru blockchain alphanet, enabling account queries, transaction status, program events, name service resolution, faucet status, and network health via the official @thru/sdk.

Enables AI agents to sign decisions with post-quantum cryptographic proofs and maintain secure audit trails for compliance. It provides tools for stamping events, verifying chain integrity, and exporting audit data across industries like finance and healthcare.

A read-only MCP server that lets any MCP-compatible AI agent inspect wallets and contracts on Base directly through natural conversation.

Enables AI agents to read Robinhood Chain stock-token positions, quote swaps, and execute swaps through the Model Context Protocol, bridging on-chain assets that Robinhood's own off-chain MCP cannot reach.

PayQL is an MCP server that lets any AI agent query The Graph and pay per query in USDC — gasless, keyless, bring-your-own-wallet.

Enables blockchain AML screening of addresses in plain language inside any MCP client, covering sanctions and freeze checks, risk scoring, fund tracing, and counterparty classification across bitcoin, ethereum, bsc, and tron. Works without an account, with an optional API key that lifts rate limits and unlocks outgoing tracing.

MCP server for Crypto APIs Prepare Transactions product that builds unsigned EVM transactions for native coin, fungible token (ERC-20), and NFT (ERC-721) transfers.

Enables AI agents to retrieve multi-chain RPC details, live pricing, weekly-probed JSON-RPC method support, and probe any EVM endpoint for diagnostics.
