MCP SERVER · OFFICIAL PROJECTLooks up the current version of a dependency before it gets pinned — across a dozen package ecosystems, GitHub Actions, and the runtimes and DevOps tools mise knows about.
LABSCO SUMMARY
Ask for the current version before the dependency is written and you skip the round of manual corrections afterwards. One practical note: models rarely reach for these tools unprompted, so say so in the request — and if you forget, asking it to update the versions it just added works after the fact too.
A version-lookup server for coding agents. It answers 'what is the latest release of this' for package registries, GitHub Actions and standalone tools, so generated files do not carry versions from the model's training window.
Three ways to run it, and one needs nothing installed at all: point your client at the free hosted endpoint https://package-version-check-mcp.onrender.com/mcp in streamable HTTP mode, run it locally with uvx package-version-check-mcp --mode=stdio, or use the Docker image ghcr.io/mshekow/package-version-check-mcp:latest --mode=stdio. The two mise-backed tools need the mise binary on PATH; the ecosystem lookups do not. GITHUB_PAT is optional and needs no scopes — it exists to keep GitHub's rate limit out of the way. Caching is off by default: PACKAGE_VERSION_CACHE_ENABLED turns it on, with PACKAGE_VERSION_CACHE_TTL_SECONDS (3600) and PACKAGE_VERSION_CACHE_MAX_SIZE_MB (64).
One command — uvx package-version-check-mcp --mode=stdio
USE CASES
Look the packages up first, then let the manifest be written with what came back.
Re-check the dependencies it just added and correct them in place.
Get each action's current tag along with the inputs and outputs it accepts.
Check the tool name is supported, then read its latest stable version.
Resolve the image tag, chart or provider version from the same call as the rest.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
get_github_action_versions_and_argsGet the latest versions and metadata for GitHub Actions.
This tool fetches the latest Git tag and action.yml metadata for GitHub Actions hosted on github.com. It can optionally include the README.md for usage instructions.
get_latest_package_versionsGet the latest versions of packages from various ecosystems.
This tool fetches the latest version information for packages from NPM, PyPI, NuGet, Maven/Gradle, Go modules, PHP/Packagist, Ruby gems, Rust crates, Swift packages, Dart packages, Docker, Helm, Terraform modules and Terraform providers. It returns both successful lookups and any errors that occurred.
get_latest_tool_versionsGet the latest stable versions of tools supported by mise-en-place.
This tool fetches the latest stable version of development and DevOps tools that are NOT part of language ecosystems like PyPI or NPM. For language ecosystem packages (including Terraform providers and modules), use the get_latest_package_versions tool instead.
Use this tool to determine the latest versions of tools like:
To see all available tools, use the get_supported_tools tool.
Args: tool_names: A list of tool names (e.g., ["terraform", "gradle", "kubectl"])
Returns: GetMiseToolVersionsResponse containing:
Example: >>> await get_latest_tool_versions( ... tool_names=["terraform", "gradle", "kubectl"] ... )
get_supported_toolsGet list of all tools supported by the get_latest_tool_versions MCP tool.
This tool queries the mise registry to retrieve all available tool names that can be used with the get_latest_tool_versions tool.
Returns: A list of tool short names (e.g., ["1password", "act", "node", "python", ...])
Example: >>> await get_supported_tools() ["1password", "act", "node", "python", ...]
BEFORE YOU INSTALL
4 tools when we connected. The "almost 1000 tools" figure refers to runtimes get_latest_tool_versions can look up, not MCP tools. get_supported_tools and get_latest_tool_versions need the mise binary on PATH.
uvx on PATH

Rated by the size of the 4 tool definitions that ride along on every turn, not by how many there are
