Clear Tape MCP

An official MCP server by Clear Tape that provides AI assistants with access to free trading calculators and educational resources. It allows agents to compute position sizes, risk/reward ratios, expectancy, Kelly criterion, and trading costs, as well as lookup glossary terms and search learning articles. The server is read-only, requires no authentication, and explicitly states it does not provide market data or investment advice.
