An MCP server that provides tools for interacting with EDUCHAIN, allowing Claude to query information about tokens and pools and perform swaps through SailFish DEX.

Enables compatible AI clients to connect to a local Coinbase Agentic Wallet through stdio MCP, so they can read wallet status, public address, Base USDC balance, and saved operations without signing, transferring, trading, or making payments.

Enables an AI agent to perform live demo trading analysis using market data, news, backtesting, breakout scanning, and persistent trading knowledge tools.

MCP server that gives AI agents a Solana wallet with a capped, revocable token allowance from a user-owned vault, enforced on-chain by SPL Token delegations plus local guardrails, without exposing the owner's private key.

CLI and local stdio MCP payment runtime for AI agents on macOS Apple Silicon. Supports x402 offer inspection and payment preparation, with signing and execution requiring foreground owner approval.

Enables local AI clients such as Claude Code and Cursor to search, analyze, and monitor prediction-market data, and, once live mode is explicitly switched on, sign and submit CLOB orders from the operator's own wallet. It runs in a safe preview mode by default, writing simulated trades to local SQLite instead of sending orders.

Enables AI agents to check their wallet address and USDC balance, preview the cost of an x402 call, and pay for API requests in USDC on Base without an account or API key. Spend caps, allow-lists and blocked contracts are enforced in code before anything is signed, so a prompt injection cannot bypass them.
