Enables AI agents to perform Web3 creator monetization actions like tipping creators, buying digital products, and managing memberships through natural language.

Enables MCP clients to use an ERC-4337 smart account with session keys to check wallet status, send ETH or ERC-20 tokens, call allowed contracts, and manage approval requests within on-chain spending limits.

Enables users to inspect Solana token mint accounts, preflight transfer actions, and verify outcome receipts without holding any keys or signing transactions.

Enables agents to perform on-chain intel and operations on Robinhood Chain, including search, charting, wallet tracking, analytics, and preparing pons launches signed in Phantom.

Enables AI agents to perform free KushBitx token previews, advisory SpendGuard policy evaluations, and discovery of unsigned x402 payment challenges through three MCP tools, with no signing or payment execution.

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 and other MCP agents to play BinCoin by checking status, planning moves, and executing actions such as claiming rewards, buying, upgrading or selling miners, and joining the game.

Enables MCP clients to fetch Argentine USD/ARS quotes, INDEC inflation data, and national holidays, validate CUIT/CBU identifiers, and generate Ripio wARS on-ramp links, with paid calls settled per use in wARS on Celo via x402 or free quote mode.

Enables AI agents to safely sign and send Solana transactions under a policy, with automatic signing for in-policy actions, air-gapped human approval for escalations, and rejection of disallowed transactions.

Enables AI agents to use pay-per-use web scraping, Base blockchain analytics, and PDF text extraction tools, monetized via x402 USDC micropayments.
