Key features
6 features of Reconstitution Calculator MCP
- Reconstitution concentration — Calculates final concentration and volume for a powder dissolved in diluent.
- Unit conversion — Converts mass, volume, or mass-concentration units across many scales.
- C1V1 dilution solver — Solves C1V1 = C2V2 for the missing value and provides diluent volume.
- Molarity calculator — Derives required mass for a target molarity or computes molarity from mass.
- Percent-w/v solution — Determines grams of solute needed for a given percent w/v solution.
- Serial dilution planner — Generates concentrations, transfer, and diluent volumes for multi-step dilutions.
Use cases
- Compute drug reconstitution concentration for lab protocols
- Convert units for chemical inventory management
- Plan serial dilutions for assay preparation

Reconstitution Calculator MCP FAQ
How do I run the server?+
Use npx: `npx -y reconstitution-calculator-mcp` or install locally with npm and run `npm start`.
Does the server store any data?+
No, it performs pure math, makes no network calls, and stores no data.
Can I host the server remotely?+
Yes, run it in HTTP mode (`--http`) or use the provided Dockerfile for container deployment.
What units are supported for conversion?+
Mass (kg, g, mg, mcg, ug, µg, ng) and volume (L, mL, uL, µL, nL) plus various mass-concentration units.
Is the tool licensed for commercial use?+
It is MIT licensed, allowing free use in commercial projects.
How does error handling work?+
Invalid inputs return clear error messages instead of numeric results.
