MCP Server: code-to-tree

The code-to-tree server's goals are:

1. Give LLMs the capability of accurately converting source code into AST(Abstract Syntax Tree), regardless of language.
2. One standalone binary should be everything the MCP client needs.

These goals imply:

1. The underlying syntax parser should be versatile enough. Here we choose tree-sitter, and languages are: C, C++, Rust, Ruby, Go, Java, Python.
2. The server should be able to carry all capabilities within itself, imposing minimum software dependencies on the end user's machine. Here we choose mcpc.

The above screenshots are obtained by asking the question specified in q.md.

(IMPORTANT NOTE: LLMs have no responsibility of generating the identical result for the same question, you will likely get a completely different style or content. The screenshots or questions provided here are just for the reference)

Using code-to-tree

Before everthing, you need to have the code-to-tree executable on your machine (code-to-tree.exe for Windows, code-to-tree for macOS), you can download at GitHub release page or build it yourself. Once downloaded, you configure your MCP clients to install it, check the section "Configure MCP Clients" for more details.

Configure MCP Clients

Here we use Claude as the example.

Windows

In your Claude configuration (C:\Users\YOUR_NAME\AppData\Roaming\Claude\claude_desktop_config.json), specify the location of code-to-tree.exe:

{
    "mcpServers": {
	    "code-to-tree": { "command": "C:\\path\\to\\code-to-tree.exe" }
    }
}

macOS

In your Claude configuration, (~/Library/Application Support/Claude/claude_desktop_config.json) specify the location of code-to-tree

{
    "mcpServers": {
	    "code-to-tree": { "command": "/path/to/code-to-tree" }
    }
}

Building (Windows)

1. Prepare environment

1. download & install MSYS2.
2. open application "MSYS2 MINGW64"
3. run pacman -S make gcc git

2. Prepare tree-sitter libraries

Here we need to compile and install tree-sitter and all related grammars.

Clone them:

git clone https://github.com/tree-sitter/tree-sitter

git clone https://github.com/tree-sitter/tree-sitter-c

git clone https://github.com/tree-sitter/tree-sitter-cpp

git clone https://github.com/tree-sitter/tree-sitter-rust

git clone https://github.com/tree-sitter/tree-sitter-ruby

git clone https://github.com/tree-sitter/tree-sitter-go

git clone https://github.com/tree-sitter/tree-sitter-java

Compile and install them:

cd tree-sitter && OS=1 make install

cd tree-sitter-c && OS=1 make install

cd tree-sitter-cpp && OS=1 make install

cd tree-sitter-rust && OS=1 make install

cd tree-sitter-ruby && OS=1 make install

cd tree-sitter-go && OS=1 make install

cd tree-sitter-java && OS=1 make install

3. Build code-to-tree

Install mcpc:

git clone https://github.com/micl2e2/mcpc
cd mcpc && make install

Compile code-to-tree:

cd mcpc/example/code-to-tree

CFLAGS="-I/usr/local/include -L/usr/local/lib" make

# Check the binary
file code-to-tree.exe

# Remember the binary's location
pwd
# Assume the output is: /c/path/to/code-to-tree.exe

Building (macOS)

1. Prepare environment

1. Xcode Command Line Tools

2. Prepare tree-sitter libraries

Here we need to compile and install tree-sitter and all related grammars.

Clone them:

git clone https://github.com/tree-sitter/tree-sitter

git clone https://github.com/tree-sitter/tree-sitter-c

git clone https://github.com/tree-sitter/tree-sitter-cpp

git clone https://github.com/tree-sitter/tree-sitter-rust

git clone https://github.com/tree-sitter/tree-sitter-ruby

git clone https://github.com/tree-sitter/tree-sitter-go

git clone https://github.com/tree-sitter/tree-sitter-java

Compile and install them:

cd tree-sitter && make install

cd tree-sitter-c && make install

cd tree-sitter-cpp && make install

cd tree-sitter-rust && make install

cd tree-sitter-ruby && make install

cd tree-sitter-go && make install

cd tree-sitter-java && make install

3. Build code-to-tree

Install mcpc:

git clone https://github.com/micl2e2/mcpc
cd mcpc && make install

Compile code-to-tree:

cd mcpc/example/code-to-tree

make

# Check the binary
file ./code-to-tree

# Remember the binary's location
pwd
# Assume the output is: /path/to/code-to-tree
