io.github.rog0x/config MCP Server

io.github.rog0x/config is an MCP server that provides tools for managing configuration files across common formats. It enables parsing, validating, merging, converting, and diffing configuration data for AI agents and model contexts.

🛠️ Key Features

Parse JSON, JSONC, YAML, TOML, INI, and other config formats
Validate content against format rules
Deep merge configurations with overlay-wins conflicts
Diff two configurations to reveal structural differences
Convert between formats (e.g., JSON to YAML)

🚀 Use Cases

Prepare model-context configurations for AI agents
Normalize and merge environment and agent settings
Validate and diff changes before deployment
Convert config files for cross-format compatibility

⚡ Developer Benefits

MCP server designed for integration with model-context workflows
Lightweight tooling for JSON, YAML, TOML, INI config management
Clear diff outputs to track configuration evolution

⚠️ Limitations

Based on provided readme excerpt; feature coverage may be limited to described tools
Requires supported formats and proper input structure for accurate diffs and merges

Tools

json_config

Read, validate, deep merge, and diff JSON/JSONC configuration files.

parse — Parse JSONC (JSON with comments and trailing commas)

validate — Check if content is valid JSON/JSONC

merge — Deep merge two JSON configs (overlay wins on conflicts)

diff — Find structural differences between two JSON configs

yaml_config

Read, validate, and convert YAML configuration files.

parse — Parse YAML content to structured data

validate — Check if content is valid YAML

to_json — Convert YAML to JSON

from_json — Convert JSON to YAML

validate_schema — Validate against docker-compose, GitHub Actions, or Kubernetes schemas

toml_parser

Parse TOML configuration files (Cargo.toml, pyproject.toml, etc.).

parse — Parse TOML content to structured data

extract_section — Extract a specific section by dot-path

list_deps — List dependencies from Cargo.toml or pyproject.toml

compare_versions — Compare two semantic version strings

ini_parser

Parse INI and properties configuration files.

parse — Parse INI content into sections and key-value pairs

get_sections — List all section names

get_value — Get a specific key from a section

to_json — Convert INI to JSON

from_json — Convert JSON back to INI format

config_diff

Compare two configuration files in any supported format.

Auto-detects file format (JSON, YAML, TOML, INI)

Cross-format comparison (e.g., compare a YAML file against a JSON file)

Shows additions, removals, and changes with full nested paths
