"Home Assistant integration with Codex or ChatGPT" matching MCP servers:

Enables interaction with Binance Smart Chain, including wallet management, token transfers, contract execution, PancakeSwap swaps, and four.meme token creation.

Enables ChatGPT and Codex to request public keys, prepare and sign exact Nostr events, encrypt or decrypt NIP-04/NIP-44 payloads, and publish with per-relay acknowledgement, while the private key stays in the user's Alby, nos2x, or remote NIP-46 signer. Every operation is queued for local browser approval, with one-use signing intents and verification before anything is broadcast.

Enables Claude to discover new Solana meme tokens, assess their risk, inspect on-chain positions, and prepare or optionally execute buy/sell transactions under configurable spend and risk guardrails. It also logs plans and trades to Google Sheets for review.

Enables an AI assistant to read token bonding curves, quote trades with fee breakdowns, monitor graduation progress, and optionally launch, buy, sell, or rescue tokens on Arc via arcnow.io.

Enables paying for Ordinal marketplace calls from your own wallet in Claude Code or Codex, with local signing and gasless settlements.

MCP server for RugGuard, enabling AI agents to perform pre-trade rug checks on tokens, with paid tools for token scanning and pre-trade verification, and a free metrics resource.

Non-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

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.
