Config
Gives Claude native access to parse, validate, merge, and convert configuration files across JSON, YAML, TOML, and INI formats. You get deep merge operations for JSON configs, schema validation for docker-compose and GitHub Actions YAML, dependency extraction from Cargo.toml and pyproject.toml, and cross-format diffs that can compare a YAML file against JSON. Reach for this when you're building agents that need to read project configs, compare environment settings, or generate configuration files without writing format-specific parsers. The config_diff tool auto-detects formats and shows nested path changes, which is handy for debugging configuration drift across environments.

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.).
