mcp-config-tools

MCP server providing configuration file tools for AI agents. Parse, validate, merge, convert, and diff configuration files across all common formats.

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
