Search the Swift Package Index for packages matching your criteria.

This is a QUERY tool — read-only, safe to call multiple times.

At least one parameter must be provided. Parameters are combined with AND logic.

Args: query: Free-text search (e.g. "networking", "json parsing"). author: Filter by repository owner (e.g. "apple", "vapor"). Prefix with "!" to exclude (e.g. "!vapor"). keyword: Filter by package keyword tag (e.g. "server", "ui"). Prefix with "!" to exclude (e.g. "!deprecated"). min_stars: Minimum GitHub star count (e.g. 100, 1000). max_stars: Maximum GitHub star count. platforms: Filter by compatible platform(s). Multiple = AND (must support all). Valid: ios, macos, watchos, tvos, visionos, linux. license_filter: License filter. Use "compatible" for App Store compatible, or a specific SPDX ID like "mit", "apache-2.0", "lgpl-2.1". Prefix with "!" to exclude (e.g. "!gpl-3.0"). last_activity_after: ISO8601 date (YYYY-MM-DD). Only packages with maintenance activity after this date. Example: "2024-01-01". last_activity_before: ISO8601 date (YYYY-MM-DD). Only packages with maintenance activity before this date. Combine with last_activity_after for a date window. last_commit_after: ISO8601 date (YYYY-MM-DD). Only packages with commits after this date. last_commit_before: ISO8601 date (YYYY-MM-DD). Only packages with commits before this date. Combine with last_commit_after for a date window. product_type: Filter by product type: library, executable, plugin, or macro. page: Page number for pagination (default 1). Check has_more in the response.

If you are unsure what values are valid for platforms or product_type, call list_search_filters() first. After getting results, use get_package_readme(owner, repo) to read the README of any package that looks interesting.

Return all valid values for the constrained parameters of search_swift_packages.

This is a DISCOVERY tool — call this first if you are unsure what values are accepted for the platforms or product_type parameters.

Returns a dict with keys 'platforms' and 'product_types', each containing the list of accepted string values.

Fetch the README of a Swift package from GitHub.

This is a QUERY tool — read-only, safe to call multiple times.

Use this after search_swift_packages to get details about a specific package. The owner and repo values come from search results (e.g. "apple" and "swift-nio").

Args: owner: GitHub repository owner (user or org). Example: "Alamofire". repo: GitHub repository name. Example: "Alamofire". max_length: Maximum characters to return (default 4000). Set to 0 for full content. Larger values use more tokens.

Returns the README content as markdown. If the README is longer than max_length, it is truncated with a note about the full length.

After reading the README, you can suggest the package to the user with its Swift Package Index URL: https://swiftpackageindex.com/{owner}/{repo}
