Connects AI agents to decentralized, community-built APIs on Solana, enabling autonomous discovery, payment, and execution of tools without subscriptions or API keys.
MCP server for witnessd, enabling agents to create tamper-evident, signed, and Merkle-anchored certificates of any public URL or API response at a moment in time.
MCP server for temporal state queries and cryptographic audit trails. Query historical entity state at any point in time, generate Merkle proofs of past state, and anchor contract snapshots for immutable provenance.
This MCP server enables agents to fetch and reason about ERC-20 token metadata, balances, and allowances across multiple chains without hardcoding addresses or ABIs.
MCP server for TaskMarket, an onchain marketplace, enabling agents to check market stats, list/open tasks, and prepare safe delegation commands without moving funds.
