One-Time Extraction

  • • Tool schemas are pulled once over stdio via tools/list and cached in ~/.mcp-tool-forge
  • • 67 registered servers yield 792 extracted tools
  • • The MCP server is only needed at conversion time, never at runtime

Two-Tier Mapping

  • • Static YAML mappings resolve 35 known tools (IAM 29 + DynamoDB 6) with zero LLM cost
  • • Only unmapped tools go to Bedrock Claude Opus 4.6 via --llm-assist
  • • Generated code passes syntax validation at 91.4% after auto-fix

Native Consumption

  • • Five output formats: boto3, AWS CLI, OpenAPI schema, AgentCore Gateway, Skill
  • • Skills load selectively (~3,000 tokens) instead of full tool schemas (~58,000 tokens)
  • • Claude Code / Kiro-CLI run the code directly - no tool-definition or round-trip tokens
