GitIngest MCP provides three tools with reasonable naming and complete schemas. All tools follow verb_noun naming convention (repository_tree_view, repository_read, find_repositories). Tool descriptions are present and explain purpose well (avg ~120 chars). Input schemas use proper JSON Schema with types and descriptions for all parameters. However, output schemas are completely undocumented, a critical gap. Tool descriptions lack dependency hints, prerequisites, or guidance on when to use one tool vs another. Parameter descriptions are adequate but could be more prescriptive about formats and constraints. Error handling is not visible in the provided code, raising concerns about recovery guidance. No tool annotations (readOnlyHint/destructiveHint/idempotentHint) despite all three being read-only operations. No pagination support visible in find_repositories despite it accepting a 'limit' parameter, total count and cursor fields should be documented or implemented. Repository_tree_view excludes/includes patterns are explained but no guidance on glob syntax or common patterns. No per-tool idempotence guarantees stated. Composition is sound, tools are single-responsibility and likely produce compatible output (all return repo metadata/file content/search results), but this is not verified from the provided source.

• Document output schemas for all three tools. For repository_tree_view: describe the tree structure (array of nodes with name, type, path, children). For repository_read: describe file content response (path, content, encoding, size, last_modified). For find_repositories: describe search results (repos array with name, url, owner, description, stars, language, total_count, has_more).
• Add readOnlyHint annotations to all three tool schemas to explicitly declare them as safe to call repeatedly without side effects.
• Enhance find_repositories description with pagination guidance: 'Returns up to limit repositories. Check has_more or next_cursor in response to paginate. Default limit is 30; max is [N].'
• Add dependency hints to find_repositories: 'Use this tool to discover repository names. Once you have a repo identifier, use repository_tree_view or repository_read to inspect contents.'
• Define git_ref as an enum with clear examples: 'one of: main (default), develop, v1.0.0 (tag format), or a commit SHA. Use tag:tagname or commit:sha format for non-branch refs.'
• Constrain exclude_patterns and include_patterns with format hints: 'Comma-separated glob patterns. Examples: *.log,*.tmp (exclude build artifacts); **/*.md,docs/** (include markdown files).'
• Add error recovery guidance in tool descriptions or a separate error catalog. Example: 'If repo not found, verify format is gitprovider:owner/repo. If API rate-limited, try again in 60 seconds.'
• Document idempotence guarantees for all tools. State: 'These tools read-only and idempotent, safe to retry on network failure.'
