yaml-mcp

MCP server: convert between YAML and JSON. Two tools — to_json and to_yaml. Multi-document YAML streams are supported.

Tools

to_json

{ "text": "name: Mukunda\nage: 30\ntags:\n  - rust\n  - python" }

→ { "value": { "name": "Mukunda", "age": 30, "tags": ["rust", "python"] } }

Set all_documents: true for multi-doc streams (a:1\n---\nb:2) — returns an array of values.

to_yaml

{ "value": { "name": "x", "tags": ["a", "b"] } }

→ multi-line YAML output. indent (default 2) controls indent width.

Configure

{ "mcpServers": { "yaml": { "command": "npx", "args": ["-y", "@mukundakatta/yaml-mcp"] } } }
