A general purpose Model Context Protocol (MCP) server that provides comprehensive developer tools for file editing, shell command execution, and screen capture capabilities. Built using the rmcp crate.
.gitignore patterns for file access controlClone the repository:
git clone git@github.com:VertexStudio/developer.git
cd developer
Build the project:
cargo build --release
The binary will be available at:
target/release/developer
For development/testing purposes:
cargo build
# Binary at: target/debug/developer
Open Claude Desktop configuration file:
macOS/Linux:
code ~/Library/Application\ Support/Claude/claude_desktop_config.json
Windows:
code %APPDATA%\Claude\claude_desktop_config.json
Add the developer server configuration:
{
"mcpServers": {
"developer": {
"command": "/path/to/your/developer/target/release/developer",
"args": []
}
}
}
Example configurations:
Development build:
{
"mcpServers": {
"developer": {
"command": "/Users/rozgo/vertex/developer/target/debug/developer",
"args": []
}
}
}
Production build:
{
"mcpServers": {
"developer": {
"command": "/Users/rozgo/vertex/developer/target/release/developer",
"args": []
}
}
}
Restart Claude Desktop to load the new configuration.
Create a .gitignore file in your working directory to control which files the server can access:
# Sensitive files
.env
.env.*
secrets.*
private/
*.key
*.pem
# Build artifacts
target/
node_modules/
dist/
The server will automatically respect these patterns and block access to matching files.
Once configured, you can use these tools directly in Claude Desktop:
"Can you view the contents of /path/to/my/file.rs?"
"Please create a new file at /path/to/hello.py with a simple hello world script"
"Replace the line 'old_function()' with 'new_function()' in /path/to/main.rs"
"Undo the last edit to /path/to/main.rs"
"Run 'ls -la' to show me the current directory contents"
"Execute 'cargo test' to run the test suite"
"Run 'git status' to check the repository status"
"Take a screenshot of my main display"
"Capture a screenshot of the window titled 'VS Code'"
"Show me what windows are available for capture"
"Process the image at /path/to/screenshot.png and show it to me"
"Load and display the image from /Users/me/Desktop/diagram.jpg"
"Start a workflow to implement a new feature with 5 steps"
"Create a branch from step 3 to explore an alternative approach"
"Revise step 2 to use a different algorithm"

Build with debug info for troubleshooting:
cargo build
# Use target/debug/developer in your configuration
Use the official MCP inspector to debug and test tools:
npx @modelcontextprotocol/inspector target/debug/developer
This will open a web interface where you can:
Export the tools JSON schema for debugging or integration:
# Save tools schema to file
cargo run toolbox > tools.json
# Pretty print tools schema
cargo run toolbox | jq .
