What Are MCPs?

Before MCP, every agent integration was custom glue code. MCP standardizes the interface, so one onchain MCP server (for wallet actions, chain data, or protocol interactions) can serve any MCP-compatible AI client. For crypto, this means blockchains become plug-and-play capabilities for any agent.

• ▸An MCP server wraps a service (an exchange API, a wallet, an RPC node, a data indexer) and exposes typed tools.
• ▸An MCP client (Claude, an IDE, a custom agent) discovers the server's tools and calls them during reasoning.
• ▸The protocol handles tool schemas, authentication, and transport, so capabilities compose across servers.
• ▸Crypto MCP servers range from read-only data access to full transaction signing, permission scope matters.

• •MCP server (exposes tools and resources)
• •MCP client (the AI application)
• •Tool schemas (typed definitions of each capability)
• •Transport layer (stdio or HTTP)
• •Authentication and permissions

• ▸Base MCP: lets an assistant transfer assets and deploy contracts on Base.
• ▸Onchain data MCPs: give research agents structured access to contract state and events.
• ▸Exchange MCPs: expose market data and trading endpoints to agents.

• ⚠A signing-capable MCP server is a high-value attack target, scope permissions tightly.
• ⚠Malicious or compromised MCP servers can feed agents bad data or exfiltrate context.
• ⚠Tool descriptions can be manipulated (tool poisoning); use trusted servers.
