## Description

MCP Tool Chainer is a server that chains multiple MCP tools together in sequence, reducing token usage by allowing sequential tool execution with result passing. Developed by Third Strand Studio, it solves the challenge of executing complex workflows without sending large intermediate results back to the LLM. The implementation features JsonPath support for precise data extraction, automatic tool discovery from configured MCP servers, and a simple interface for defining tool chains where results from one tool can be passed as input to another using the CHAIN_RESULT placeholder.
