ArXiv MCP ServerMCP Server44/100 via “mcp protocol tool registration and request routing”
Search and read arXiv academic papers and abstracts via MCP.
Unique: Implements full MCP server compliance with tool schema registration, async request handling, and error propagation. Tools are registered with structured schemas that define input parameters, output types, and descriptions, enabling AI assistants to understand and invoke tools with type safety. Uses stdio transport for communication, making it compatible with Claude and other MCP clients.
vs others: More standardized than custom HTTP APIs because it uses the MCP protocol, enabling seamless integration with Claude and other MCP-compatible tools without custom client code; provides type safety and automatic input validation that REST APIs require manual implementation for.
