What types of isomers are supported?

The tool identifies constitutional isomers, specifically covering chain, position, and functional group isomers.

How can I check if a formula is valid?

You can use the `validate_formula_feasibility` tool to check if a molecular formula follows standard organic valence rules.

Does it provide IUPAC names?

Yes, `list_isomer_details` provides the official IUPAC name for every identified isomer.

This MCP server provides specialized tools for organic chemistry analysis. It allows AI agents to determine the total number of unique constitutional isomers for a given molecular formula using get_isomer_count. Users can retrieve detailed structural information, including IUPAC names and condensed formulas, via list_isomer_details. The server also categorizes isomers into chain, position, or functional groups using get_isomer_classification, and ensures chemical validity with validate_formula_feasibility.
