MCP Servers

latex-mcp

An MCP server that renders LaTeX math expressions and step-by-step solutions into high-quality PNG images and hosted URLs. It enables AI assistants to provide visual mathematical solutions formatted for messaging platforms like iMessage.

README

latex-mcp 🧮

An MCP server that renders LaTeX math expressions into beautiful PNG images — built for AI assistants like Poke that solve math problems from photos.

How It Works

User sends photo of math problem
→ AI (Poke) solves it
→ AI calls this MCP server with the LaTeX solution
→ Server renders it into a clean PNG image
→ AI sends the image URL back in iMessage

Tools

`render_solution` ⭐ (Primary tool)

Renders a full step-by-step solution with highlighted final answer. Returns both a hosted image URL (for iMessage) and a base64 PNG.

`get_image_url`

Returns a hosted CodeCogs URL for any LaTeX expression — iOS renders it inline in iMessage.

`render_latex`

Renders LaTeX to a base64-encoded PNG for embedding.

    }
  }
}

Example Usage

When Poke solves 2x + 4 = 10, it should call:

{
  "tool": "render_solution",
  "params": {
    "problem_description": "Solve for x: 2x + 4 = 10",
    "steps_latex": ["2x + 4 = 10", "2x = 10 - 4", "2x = 6", "x = \\frac{6}{2}"],
    "final_answer_latex": "x = 3"
  }
}

Returns an image_url to send directly in iMessage. 🎉
