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.

MCP Endpoint

https://latex-mcp.onrender.com/mcp

Connect to Poke / Claude Desktop

{ "mcpServers": { "latex-mcp": { "command": "npx", "args": ["mcp-remote", "https://latex-mcp.onrender.com/mcp"] } } }

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. 🎉
