Package Version MCP Server
An MCP server that provides tools for checking latest stable package versions from multiple package registries:
- npm (Node.js/JavaScript)
- PyPI (Python)
- Maven Central (Java)
- Go Proxy (Go)
- Swift Packages (Swift)
- AWS Bedrock (AI Models)
- Docker Hub (Container Images)
- GitHub Container Registry (Container Images)
- GitHub Actions
This server helps LLMs ensure they're recommending up-to-date package versions when writing code.
IMPORTANT: As of version 2.0.0, mcp-package-version has been rewritten in Go, as such the configuration needs to be updated in your client - see the Installation section for more details.

Installation
Requirements:
- A modern go version installed (See Go Installation)
Using go install
(Recommended for MCP Client Setup):
Then setup your client to use the MCP server. Assuming you've installed the binary with go install github.com/sammcj/mcp-package-version/v2@HEAD
and your $GOPATH
is /Users/sammcj/go/bin
, you can provide the full path to the binary:
- For the Cline VSCode Extension this will be
~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json
- For Claude Desktop
~/Library/Application\ Support/Claude/claude_desktop_config.json
- For GoMCP
~/.config/gomcp/config.yaml
Other Installation Methods
Or clone the repository and build it:
You can also run the server in a container:
Note: If running in a container, you'll need to configure the client to use the URL instead of command, e.g.:
Tip: Go Path
If $GOPATH/bin
is not in your PATH
, you'll need to provide the full path to the binary when configuring your MCP client (e.g. /Users/sammcj/go/bin/mcp-package-version
).
If you haven't used go applications before and have only just installed go, you may not have a $GOPATH
set up in your environment. This is important for any go install
command to work correctly.
Understanding
$GOPATH
The
go install
command downloads and compiles Go packages, placing the resulting binary executable in thebin
subdirectory of your$GOPATH
. By default,$GOPATH
is > usually located at$HOME/go
on Unix-like systems (including macOS). If you haven't configured$GOPATH
explicitly, Go uses this default.The location
$GOPATH/bin
(e.g.,/Users/your_username/go/bin
) needs to be included in your system'sPATH
environment variable if you want to run installed Go binaries directly by name from any terminal location.You can add the following line to your shell configuration file (e.g.,
~/.zshrc
,~/.bashrc
) to set$GOPATH
to the default if it's not already set, and ensure$GOPATH/bin
is in yourPATH
:CopyAfter adding this line, restart your terminal or MCP client.
Usage
The server supports two transport modes: stdio (default) and SSE (Server-Sent Events).
STDIO Transport (Default)
SSE Transport
This would make the server available to clients at http://localhost:18080/sse
(Note the /sse
suffix!).
Command-line Options
--transport
,-t
: Transport type (stdio or sse). Default: stdio--port
: Port to use for SSE transport. Default: 18080--base-url
: Base URL for SSE transport. Default: http://localhost
Docker Images
Docker images are available from GitHub Container Registry:
You can also see the example docker-compose.yaml.

Releases and CI/CD
This project uses GitHub Actions for continuous integration and deployment. The workflow automatically:
- Builds and tests the application on every push to the main branch and pull requests
- Creates a release when a tag with the format
v*
(e.g.,v1.0.0
) is pushed - Builds and pushes Docker images to GitHub Container Registry
