starknet

Official StarkWare MCP (Model Context Protocol) server that exposes all Starknet JSON-RPC v0.10.2+ read and trace methods as agent tools, letting an assistant read blocks, transactions, state, classes, events, and traces from a live Starknet node. Ships in the starknet-specs repo with a Claude Code slash-command installer (/install-starknet-mcp).

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
