Terragrunt-Docs

Implements a Model Context Protocol (MCP) server that exposes Terragrunt documentation as a queryable resource, enabling Claude and other MCP-compatible clients to fetch up-to-date Terragrunt reference material without manual web searches. The server acts as a documentation bridge, parsing and serving Terragrunt docs through standardized MCP resource endpoints that integrate seamlessly into LLM context windows.

Maps Terragrunt configuration options to their documentation references, enabling validation of HCL/YAML configurations against the official schema. This capability parses Terragrunt blocks (remote_state, dependencies, inputs, etc.) and cross-references them with documentation to provide inline validation hints and usage examples.

Analyzes Terragrunt configurations and recommends improvements based on official documentation patterns, common pitfalls, and best practices. Uses documentation-backed heuristics to identify anti-patterns (e.g., missing dependency declarations, improper remote state configuration) and suggests corrections with links to relevant documentation sections.

Maintains indexed documentation for multiple Terragrunt versions, enabling queries against specific version documentation. The MCP server can serve version-specific docs and highlight breaking changes or feature availability across versions, allowing users to understand compatibility implications of their configuration choices.

Provides documentation-backed guidance on Terragrunt dependency declarations and resolution. Explains how dependencies work, documents the dependency block syntax, and helps users understand dependency ordering implications for their infrastructure deployments. Integrates with documentation to show examples of complex dependency patterns.

Provides comprehensive documentation and validation for Terragrunt remote_state blocks, covering backend configuration options, state locking, and storage backend specifics. Validates remote state configurations against documented best practices and explains backend-specific options with links to relevant documentation sections.
