"YAML" matching MCP servers:

Enables building LangGraph projects by editing a structured YAML spec, with MCP tools for scaffolding, adding nodes/edges, validating, and deterministically rendering Python graph code.

A local, auditable multi-model workflow engine that lets you define YAML graphs for orchestrating LLM agents across vendors, with MCP tools for validation, dry-runs, execution, and human approval, all fully observable in a local web interface.

Validate and generate SOUL.md agent identity files. SOUL.md is the open format for persistent AI agent identity — personality, voice, values, and constraints in a machine-readable YAML file.

Exposes the full Telnyx API as Model Context Protocol tools and enables deploying autonomous AI voice agents from a YAML spec.

A minimal, production-ready FastMCP server template with auto-discovery, YAML configuration, authentication, and a knowledgebase, enabling quick scaffolding of new MCP servers.
