# 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
```json
{
"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:
```json
{
"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. 🎉
