# PeptideCalc MCP Server

The official Model Context Protocol (MCP) server for [PeptideCalculatorOnline.com](https://peptidecalculatoronline.com). 

This server empowers AI assistants (like Claude, Cursor, and ChatGPT) with precise, clinical-grade mathematical logic for calculating peptide reconstitution matrices, avoiding the dangerous "hallucination" of dosages by LLMs.

## 🚀 Key Features

* **Absolute Math Accuracy:** Replaces LLM guess-work with the deterministic algebraic mapping used on our official calculator ($V_{draw} = \frac{D}{C}$).
* **U-100 Syringe Mapping:** Automatically converts complex dosages into exact "Unit" pulls for standard U-100 insulin syringes.
* **Standard Protocols:** Instant access to widely accepted laboratory research protocols for compounds like Semaglutide, BPC-157, TB-500, Tirzepatide, etc.
* **Plunger Parallax Guidelines:** Educates researchers on volumetric resolution and how to avoid hyper-condensed solutions.

## 🛠 Available Tools

1. `calculate_reconstitution_dose`: Input peptide (mg), bacteriostatic water (ml), and desired dose (mg). Returns the exact concentration (mg/ml) and U-100 syringe units.
2. `get_peptide_protocol`: Input a standard analog name (e.g., `semaglutide`, `bpc-157`) to receive standard starting titrations and matrices.
3. `get_syringe_mechanics_guide`: Learn about standard operating procedures to reduce dosage errors.

## 💻 Installation
