Workflows Mcp Server
Gives Claude four operations to manage YAML workflow playbooks: list permanent workflows by category or tag, retrieve a specific workflow with global instructions prepended, create new permanent workflows in the library, and write temporary one-shot workflows. Built on the mcp-ts-core framework with a filesystem-backed in-memory index, semver-aware versioning, and automatic rebuilds when workflow files change. Includes tools enumeration so you can see which MCP servers a workflow depends on before running it. Useful when you're orchestrating multi-step agent tasks and want structured, reusable playbooks instead of freeform prompting. Runs over stdio or streamable HTTP with no API keys required.
