It follows a strict fail-hard policy and always returns current data.\n\n## Features\n\n- **19 Package Registries**: npm, RubyGems, PyPI, Hex.pm, crates.io, Bioconda, CRAN, Terraform Registry, DockerHub, CPAN, Go modules, Composer, NuGet, Homebrew, Nextflow, nf-core modules, nf-core subworkflows, Swift Package Manager, Maven Central\n- **Language/Ecosystem Aliases**: Use familiar names like `python`, `rust`, `go`, etc.\n- **No Caching**: Always returns current latest version\n- **Fail-Hard Error Handling**: No fallbacks or stale data\n- **Rich Metadata**: Package descriptions, homepages, and license information\n- **Configurable Timeouts**: Adjust API request timeouts as needed\n- **Test Client Included**: `vmcp` command-line tool for testing and manual queries\n- **Optimized for Claude Desktop Integration**\n\n## Quick Start\n\n### Option 1: Using uvx (Recommended)\n\nThe easiest way to use Versionator with Claude Desktop is via [uvx](https://github.com/astral-sh/uv):\n\n```bash\n# Install uvx if you haven't already\ncurl -LsSf https://astral.sh/uv/install.sh | sh\n\n# Run Versionator directly with uvx\nuvx versionator-mcp\n```\n\n### Option 2: Install Locally\n\n```bash\n# Install from PyPI\npip install versionator-mcp\n\n# Or install with pipx for isolated environment\npipx install versionator-mcp\n```\n\n## Editor Integration\n\n### Claude Desktop\n\nAdd configuration to your Claude Desktop MCP settings:\n\n**Config Location:**\n- **macOS**: `~/Li…","publisher":null,"homepage":"https://github.com/trianglegrrl/versionator-mcp","repository":"https://github.com/trianglegrrl/versionator-mcp","version":"1.3.1","license":"MIT","protocols":["mcp"],"tags":["mcp","model-context-protocol","package-manager","npm","pypi","rubygems","hex"],"pricing":null,"endpoints":[{"url":"pypi:versionator-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi"}},"derived":{"capabilities":[{"slug":"dev.package-management","name":"Packages & Dependencies","confidence":1,"provenance":"declared"},{"slug":"dev.terminal","name":"Terminal & Shell","confidence":0.825,"provenance":"derived"},{"slug":"dev.ci-cd","name":"CI/CD & Deploy","confidence":0.756,"provenance":"derived"}],"categories":["dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"versionator-mcp","registry":"pypi","observedAt":"2026-09-10T15:25:09.277Z","publishedAt":"2025-08-20T10:28:39.485941Z","latestVersion":"1.3.1"}},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"versionator-mcp","url":"https://pypi.org/project/versionator-mcp/","firstSeenAt":"2026-09-10T15:23:25.078Z","fetchedAt":"2026-09-10T15:23:25.078Z","normalizedAt":"2026-09-10T15:23:25.078Z"}]},"firstSeenAt":"2026-09-10T15:23:25.078Z","updatedAt":"2026-09-10T15:25:09.277Z"}
