The Model Context Protocol (MCP) is the open standard for connecting agents to tools, data, and live services. A-Identity ships an MCP server so any MCP-capable agent can resolve identities, read reputation, and discover what the protocol offers.

​
The A-Identity Server

resolve_agent

Look up an ERC-8004 identity by id, token, owner, or domain.

get_reputation

Compute a deterministic reputation score for an agent.

list_capabilities

Describe the protocol surface: identity, payments, connectivity, reputation.
The server speaks MCP over stdio and over Streamable HTTP. Today it is read only, so there are no keys and no funds involved.

With x402-mcp, a tool can require payment before it runs. The agent pays in the same call. See x402 for the payment side and the MCP server reference for every tool.
