"TypeScript type checking tool or function" matching MCP servers:

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

A tool that enables users to interact with blockchain data to retrieve token total supply, chain IDs, and filtered RPC endpoints across different blockchain networks.

A Model Context Protocol tool that provides weather information for cities, with London access requiring Solana devnet payment via the Latinum Wallet MCP server.

Official CoinGecko API MCP Server for Crypto Price & Market Data. More details: https://docs.coingecko.com/reference/mcp-server

Provides an MCP server that allows large language models to access real-time and historical Bitcoin market data from Binance, including current prices, order book data, recent trades, and price history through a standardized interface.

Enables AI agents to deploy and manage compliant tokens across multiple blockchains (EVM, Solana, Stellar) using natural language, with features like whitelist, blacklist, and pausable contracts.

Enables AI agents to optimize context by pruning large JSON payloads, enforcing token budgets, and handling x402 micropayments via Base blockchain.

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.

Enables static analysis of Solidity smart contracts using Slither, including contract metadata, function details, inheritance, and security detectors through MCP tools.

Provides tools and prompts for Bitcoin SV development, enabling code search, BRC lookup, and function definition search within locally cloned BSV repositories.

Lets you probe ERC-8004 agents on BNB Smart Chain by calling their declared MCP or A2A endpoints, checking payment requirements, reading on-chain reputation authorship, and finding agents by description.

Pay-per-call MCP server for checking MEV exposure, sandwich attacks, and pool MEV density on EVM chains, with no signup or API key required.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

Screens the counterparty of an x402 payment before an agent pays it. One tool, screen_payment, checks address sanity, dynamic-payTo swaps, transport safety and your spend policy, then returns allow / review / block with the reasons — advisory only, and by default it runs with no key, no account and no network call.

Resolves a company name, registrable domain, or LEI to its GLEIF legal entity record — LEI, legal name, jurisdiction, entity status, and registration status — for $0.05 USDC on Base paid per call over x402, with no signup or API key. Includes a free, no-wallet preview of price and coverage plus hard per-call and per-session spend caps, while misses and ambiguous matches cost nothing.

Enables static security audit of Solidity smart contracts by analyzing source code or deployed bytecode for vulnerabilities, providing risk scores and detailed findings.

Enables AI agents on Base to call a check_token_risk tool before trading, providing honeypot detection, LP-lock verification, brand impersonation checks, and live sell simulation across Uniswap V2/V3/V4 and Aerodrome with a clear risk score and should-trade decision.

Enables AI agents to verify other agents' revenue claims by recomputing Merkle roots locally and checking on-chain anchors on Base.

Quick-scan a smart contract for rug, honeypot, or centralization risk before sending funds. It combines verified source, live on-chain state, and heuristic Solidity analysis to return a SAFE/CAUTION/HIGH-RISK verdict.
