Setup
Install AST2LLM for Go in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/vprud/ast2llm-go
Follow the installation instructions in the repository README, then restart your MCP client.
Local AST-powered context enhancement tool for LLM
Automatically injects relevant code structure into your prompts using precise Go AST analysis.
Our MCP server provides theparse-gotool that:
- Analyzes your Go project structure
- Identifies external type declarations
- Packages context for LLM prompts
- Delivers 3-5x faster context resolution than grap-based approaches
For example, the demo above shows the model calling the tool to get the missing information about the fields of theMyDTOstructure. In response, the model received all the necessary information from the response:
Used Imported Structs (from this project, if available): Struct: testme/dto.MyDTO Fields: - Foo string - Bar int
- Go 1.22 or higher (if building from source)
- Supported MCP client (Cursor, Claude, VS Code, etc.)
To installast2llm-goon your system, run the following command in your terminal:
curl -LsSf https://raw.githubusercontent.com/ast2llm/ast2llm-go/main/install.sh | sh
This script will automatically detect your OS and architecture, download the appropriate binary, and attempt to add it to your PATH. You can also specify an installation directory:
curl -LsSf https://raw.githubusercontent.com/ast2llm/ast2llm-go/main/install.sh | sh -s -- --install-dir /usr/local/bin
To updateast2llm-goto the latest version, simply re-run the installation command:
curl -LsSf https://raw.githubusercontent.com/ast2llm/ast2llm-go/main/install.sh | sh
To removeast2llm-gofrom your system, run the uninstallation script:
curl -LsSf https://raw.githubusercontent.com/ast2llm/ast2llm-go/main/uninstall.sh | sh
This script will remove the binary, clean up PATH modifications, and delete related configuration files. You may need to restart your shell after uninstallation.
After installationast2llm-go, you need to restart the IDE.
