"Servers that Enhance Productivity" matching MCP servers:

Provides secure, audited MCP servers for Kadena blockchain interactions, including Pact smart contract operations, Chainweb API, module deployment, and security scanning.

An MCP server and Python toolkit that provides AI agents with real-time tools for Polymarket prediction markets, including liquidity scanning, arbitrage detection, and slippage estimation. It also offers advanced wallet intelligence, portfolio risk calculation, and probabilistic reasoning to enhance market analysis and strategy.

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 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 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 lets AI agents interact with NIGHTGATE, the Midnight blockchain attestation layer, to anchor documents, verify zero-knowledge predicates, manage disclosure grants, and poll async jobs.

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

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.

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.

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.

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

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.

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.
