DevDocsMCP is a command-line tool that allows you to search and read documentation directly from DevDocs.io. It operates purely online, fetching data as needed.

1. Go Installation: Ensure you have Go installed on your system. You can download it from golang.org.

2. Clone the Repository:

   git clone https://github.com/kelvinzer0/DevDocsMCP.git
   cd DevDocsMCP

3. Build the Application:

   go build -o devdocsmcp cmd/devdocsmcp/main.go

   This will create an executable named devdocsmcp in the current directory.

Navigate to the DevDocsMCP directory in your terminal.

To search for a term within a specific documentation set:

./devdocsmcp search -lang <language_slug> -query <search_query>

• <language_slug>: The slug for the documentation (e.g., html, css, angularjs~1.8, vite, tailwindcss, go, mysql, sqlite). You can find a list of available documentation on DevDocs.io.
• <search_query>: The term you want to search for.

Examples:

• Search for "display" in HTML documentation:

  ./devdocsmcp search -lang html -query display

• Search for "foreach" in AngularJS 1.8 documentation:

  ./devdocsmcp search -lang angularjs~1.8 -query foreach

To read the content of a specific documentation entry:

./devdocsmcp read -lang <language_slug> -path <entry_path>

• <language_slug>: The slug for the documentation (e.g., html, css, angularjs~1.8).
• <entry_path>: The path to the specific documentation entry, as found in search results (e.g., reference/elements/a, api/ng/function/angular.foreach).

Examples:

• Read the documentation for the HTML <a> element:

  ./devdocsmcp read -lang html -path reference/elements/a

• Read the documentation for angular.forEach:

  ./devdocsmcp read -lang angularjs~1.8 -path api/ng/function/angular.foreach

DevDocsMCP can also run as an HTTP server, exposing its search and read functionalities via API endpoints. This is useful for integrating with other tools or services.

To start the server:

./devdocsmcp server [-port <port_number>] -lang <comma_separated_languages>

• -port: Optional. The port number for the server to listen on. Defaults to 8080.
• -lang: Optional. A comma-separated list of language slugs that this server instance should serve (e.g., html,css). If omitted, all languages will be allowed.

Example MCP Server Configuration:

To configure DevDocsMCP as an MCP server, you can add a section like this to your MCP configuration file:

{
  "mcpServers": {
    "devdocs-html": {
        "command": "/path/to/your/DevDocsMCP/cmd/devdocsmcp",
        "args":["server", "--lang", "html"]
    },
    "devdocs-css": {
        "command": "/path/to/your/DevDocsMCP/cmd/devdocsmcp",
        "args":["server", "--lang", "css"]
    },
    "devdocs-vite": {
        "command": "/path/to/your/DevDocsMCP/cmd/devdocsmcp",
        "args":["server", "--lang", "vite"]
    },
    "devdocs-tailwindcss": {
        "command": "/path/to/your/DevDocsMCP/cmd/devdocsmcp",
        "args":["server", "--lang", "tailwindcss"]
    },
    "devdocs-go": {
        "command": "/path/to/your/DevDocsMCP/cmd/devdocsmcp",
        "args":["server", "--lang", "go"]
    },
    "devdocs-mysql": {
        "command": "/path/to/your/DevDocsMCP/cmd/devdocsmcp",
        "args":["server", "--lang", "mysql"]
    },
    "devdocs-sqlite": {
        "command": "/path/to/your/DevDocsMCP/cmd/devdocsmcp",
        "args":["server", "--lang", "sqlite"]
    }
  }
}

Note: Replace /path/to/your/DevDocsMCP/cmd/devdocsmcp with the actual absolute path to your devdocsmcp executable. The key "devdocs-html-css" can be any unique identifier for this server.

To display the languages that the devdocsmcp server is configured to allow:

./devdocsmcp allowed-langs

This command will show the languages that were specified with the -lang flag when the server was started. If no languages were specified, it will indicate that all languages are allowed.

You can download pre-built binaries for various operating systems and architectures directly from the GitHub Releases page.

Replace [VERSION] with the desired release version (e.g., v1.0.0).

# Download the binary (replace [OS] and [ARCH] with your system, e.g., linux_amd64, darwin_arm64)
wget https://github.com/kelvinzer0/DevDocsMCP/releases/download/[VERSION]/devdocsmcp_[OS]_[ARCH] -O devdocsmcp

# Make it executable
chmod +x devdocsmcp

# Move it to a directory in your PATH (e.g., /usr/local/bin)
sudo mv devdocsmcp /usr/local/bin/

Download the appropriate .exe file from the GitHub Releases page (e.g., devdocsmcp_windows_amd64.exe). Rename the downloaded file to devdocsmcp.exe. Move devdocsmcp.exe to a directory that is included in your system's PATH environment variable. A common practice is to create a bin folder in your user directory (e.g., C:\Users\YourUser\bin) and add it to PATH.
