How to Set Up and Use Local Go Context
MCP Local Context is a Go-based MCP server that helps AI assistants work accurately with third-party Go packages by grounding them in your local Go module cache rather than relying on potentially outdated training data. It provides tools for language detection, context instruction retrieval, and custom prompt discovery, preventing hallucinated API signatures when working with real project dependencies.
Prerequisites
- Go 1.18+ installed with a working GOPATH and module cache
- An MCP-compatible client such as Claude Desktop, Cursor, or GitHub Copilot
- Go modules initialized in your project (go.mod present)
- GOPATH/pkg/mod directory populated with cached dependencies
Install mcp-local-context
Install the server binary directly using go install. This places the binary in your Go bin directory.
go install github.com/svetlyi/mcp-local-context@latestVerify the installation
Confirm the binary is on your PATH and runs correctly.
which mcp-local-context
mcp-local-context --helpCreate the configuration file
Create the config directory and an optional config.json to set log level and custom prompt directories.
mkdir -p ~/.mcp-local-context
cat > ~/.mcp-local-context/config.json << 'EOF'
{
"log_level": "info",
"log_file": "~/.mcp-local-context/mcp.log",
"custom_prompt_dirs": []
}
EOFAdd to your MCP client configuration
Register the server in your Claude Desktop or Claude Code MCP configuration using the installed binary path.
{
"mcpServers": {
"mcp-local-context": {
"command": "/Users/yourname/go/bin/mcp-local-context"
}
}
}Add custom prompts (optional)
Place custom Markdown prompt files in ~/.mcp-local-context/prompts/ with YAML front matter to define language-specific context instructions available to the AI.
mkdir -p ~/.mcp-local-context/prompts
cat > ~/.mcp-local-context/prompts/my-go-rules.md << 'EOF'

title: My Go Project Rules
lang: go

Always check go.mod for the exact module version before suggesting API calls.

Client configuration
Example claude_desktop_config.json for mcp-local-context using the Go-installed binary.
{
"mcpServers": {
"mcp-local-context": {
"command": "/Users/yourname/go/bin/mcp-local-context"
}
}
}Prompts to try
Reference the built-in golang-context-rule prompt or ask the server to detect your language and fetch appropriate context instructions.
- "I'm working with the github.com/gin-gonic/gin package, use the /local_context/golang-context-rule prompt to guide your answers"
- "What version of the 'zap' logger package is in my go.mod and what's the correct API for creating a production logger?"
- "Using local context, find and show me the actual function signatures for the pgx/v5 connection pool"
- "Detect the language of my current project and get appropriate context instructions"Troubleshooting Local Go Context
Binary not found after go install
Ensure your Go bin directory is on your PATH. Add 'export PATH=$PATH:$(go env GOPATH)/bin' to your shell profile (~/.zshrc or ~/.bashrc) and reload it with 'source ~/.zshrc'.
Server cannot find Go module cache for a package
Run 'go mod download' in your project directory to ensure all dependencies are present in the local cache at $(go env GOMODCACHE). The server reads directly from this cache directory.
Custom prompts not appearing in the MCP client
Verify your .md files in ~/.mcp-local-context/prompts/ have valid YAML front matter with at minimum a 'title' key. Check the log file at the path configured in config.json for any parsing errors.
