Features

• 📐 render_latex: Convert LaTeX expressions to beautiful Unicode art
• 📝 render_markdown: Process markdown files with embedded LaTeX expressions
• 🔍 check_texicode_version: Verify TeXicode installation
• 📚 Resources: Example LaTeX expressions and server configuration
• ⚙️ Flexible Configuration: CLI args, environment variables, or defaults

Demo

Here's example of what this project can do. First, configure the MCP server with your agentic coding tool of choice, eg. IBM Bob, Claude Code, Codex, etc. and make sure mcp-texicode appears in the mcp servers list.

Send a prompt like the following example.

Prompt:

Claude Desktop Configuration

To use with Claude Desktop, add to your claude_desktop_config.json:

macOS

Location: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows

Location: %APPDATA%\Claude\claude_desktop_config.json

Configuration Examples

1. Using uv with Local Clone (Recommended for Development)

If you've cloned the repository locally and want to use uv for dependency management:

{
  "mcpServers": {
    "texicode": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/mcp-texicode",
        "run",
        "mcp-texicode"
      ]
    }
  }
}

Note: Replace /absolute/path/to/mcp-texicode with the actual path to your cloned repository.

Example paths:

• macOS/Linux: "/Users/username/Code/mcp-texicode"
• Windows: "C:\\Users\\username\\Code\\mcp-texicode"

2. Using uv with Installed Package

If you've installed mcp-texicode via pip/uv:

{
  "mcpServers": {
    "texicode": {
      "command": "uvx",
      "args": ["mcp-texicode"]
    }
  }
}

3. Using Python Directly

{
  "mcpServers": {
    "texicode": {
      "command": "python",
      "args": ["-m", "mcp_texicode.server"]
    }
  }
}

4. With Custom Configuration (Environment Variables)

{
  "mcpServers": {
    "texicode": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/mcp-texicode",
        "run",
        "mcp-texicode"
      ],
      "env": {
        "MCP_TRANSPORT": "stdio",
        "MCP_LOG_LEVEL": "INFO",
        "MCP_DEBUG": "false"
      }
    }
  }
}

5. With Custom Configuration (CLI Arguments)

{
  "mcpServers": {
    "texicode": {
      "command": "python",
      "args": [
        "-m",
        "mcp_texicode.server",
        "--transport",
        "stdio",
        "--log-level",
        "INFO"
      ]
    }
  }
}

6. Using Virtual Environment

If you have a specific virtual environment:

{
  "mcpServers": {
    "texicode": {
      "command": "/absolute/path/to/venv/bin/python",
      "args": ["-m", "mcp_texicode.server"]
    }
  }
}

Verifying Configuration

After updating your configuration:

1. Restart Claude Desktop completely (quit and reopen)
2. Check the MCP icon in Claude Desktop - it should show the texicode server
3. Test a tool by asking Claude to render a LaTeX expression

Example prompt to test:

Can you render the quadratic formula using the texicode server?

Output Filtering

By default, the server filters ANSI escape sequences from TeXicode output to provide clean Unicode art. This is because the TeXicode CLI (txc) can output color formatting codes that may not be desired in all contexts.

Why Filtering?

• Without filtering: txc -c "x^2" outputs 30 bytes including ANSI color codes: \x1b[38;5;232m\x1b[48;5;255mx²\x1b[0m
• With filtering (default): Same expression outputs clean 4 bytes: x²

Disabling Filters

If you want to preserve ANSI escape sequences (e.g., for color output in terminals that support it):

Using CLI argument:

python -m mcp_texicode.server --no-escape-filters

Using environment variable:

MCP_NO_ESCAPE_FILTERS=true python -m mcp_texicode.server

In Claude Desktop config:

{
  "mcpServers": {
    "texicode": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/mcp-texicode",
        "run",
        "mcp-texicode",
        "--no-escape-filters"
      ]
    }
  }
}
