# pylipidparse

This MCP server turns full lipid shorthand into SMILES, InChI, InChIKey, MOL, and SDF outputs. Use it to inspect chemical structures from Claude Code.

## What it does

pylipidparse exposes PyLipidParse in Claude Code as an MCP server. Give it a complete lipid notation such as `PC 16:0/18:1(9Z)` or `Cer 18:1;O2/16:0`, and it can return canonical SMILES, InChI, and InChIKey values. It can also produce MOL files with 2D coordinates and SDF output for a batch of lipids.

The plugin accepts LIPID MAPS, Goslin, SwissLipids, and HMDB notation dialects. Its supported classes include fatty acids, glycerolipids, glycerophospholipids, sphingolipids, and sterols. A shorthand such as `PC 34:1` is insufficient; the structural form must include the required detail.

You need `uv` before using the server. It runs through `uvx`, which installs `pylipidparse[mcp]` on the first request and reuses the cached environment later. The initial setup may take 30–60 seconds. Without `uv`, the MCP server will not start.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install pylipidparse@claude-community
```

## When to use it
- convert full lipid notation into SMILES
- look up an InChIKey for PubChem or LIPID MAPS
- export a lipid structure as a MOL file
- generate an SDF file for several lipids

## Example prompts
- Convert `PC 16:0/18:1(9Z)` into a SMILES string.
- Find the InChIKey for oleic acid, written as `FA 18:1(9Z)`.
- Create an SDF file from this list of ceramides: ...

# PyLipidParse Claude Code Plugin

This plugin exposes [PyLipidParse](https://github.com/MontgomeryBohde/PyLipidParse) as an MCP server inside Claude Code, letting you convert lipid shorthand notation to molecular structures directly in your AI assistant.

## What it does

Converts lipid names like `PC 16:0/18:1(9Z)` or `Cer 18:1;O2/16:0` into:
- Canonical **SMILES** strings
- **InChI** identifiers
- **InChIKey** hashes (for PubChem / LIPID MAPS database lookups)
- **MOL files** with 2D coordinates
- **SDF files** for multiple lipids at once

Supports LIPID MAPS, Goslin, SwissLipids, and HMDB notation dialects.

## Requirements

- [uv](https://docs.astral.sh/uv/) must be installed (used to run the server without pre-installation)

## Installation

Install this plugin from the Claude Code plugins directory, or manually:

```bash
claude --plugin-dir /path/to/PyLipidParse/claude-code-plugin
```

The MCP server runs via `uvx` and installs `pylipidparse[mcp]` automatically on first use. Subsequent runs use the cached environment.

## Manual MCP configuration (without the plugin)

Add to your `.mcp.json` or Claude Code MCP config:

```json
{
  "mcpServers": {
    "pylipidparse": {
      "command": "uvx",
      "args": ["--from", "pylipidparse[mcp]", "pylipidparse-mcp"]
    }
  }
}
```

Or if you have `pylipidparse[mcp]` already installed:

```json
{
  "mcpServers": {
    "pylipidparse": {
      "command": "pylipidparse-mcp"
    }
  }
}
```

## Example prompts

- *"Convert PC 16:0/18:1(9Z) to SMILES"*
- *"What is the InChIKey for oleic acid (FA 18:1(9Z))?"*
- *"Give me SMILES and InChIKey for these 10 lipids: ..."*
- *"Generate an SDF file for this list of ceramides"*

## Supported lipid classes

Fatty acids (FA), glycerolipids (MAG/DAG/TAG), glycerophospholipids (PC/PE/PA/PI/PS/PG and lyso variants), sphingolipids (Cer/SM/HexCer/LacCer/SPB), and sterols (Cholesterol/CE/bile acids).

## Notes

- **Full structural notation required** — use `PC 16:0/18:1(9Z)`, not `PC 34:1`
- First run may take 30–60 seconds while `uvx` installs dependencies
