About mcp_tool_chainer

An MCP (Model Context Protocol) server that chains calls to other MCP tools, reducing token usage by allowing sequential tool execution with result passing. Designed to solve https://github.com/modelcontextprotocol/specification/issues/215

Features

  • Chain multiple MCP tools together in sequence

  • Pass results from one tool as input to another tool using CHAIN_RESULT placeholder

  • Filter and extract specific data using JsonPath with inputPath and outputPath parameters

  • Automatic tool discovery from configured MCP servers

  • Minimal token usage compared to individual tool calls

Tools (5)

  • mcp_chain

    Chain together multiple MCP servers

  • chainable_tools

    Discover tools from all MCP servers so the mcp_chain tool can be used

  • discover_tools

    Rediscover tools from all MCP servers

  • inputPath

    JsonPath expression to extract specific portions of the input before passing to a tool

  • outputPath

    JsonPath expression to extract specific portions of the output before passing to the next tool
