Support

Help with accounts, chemistry data, MCP connections, OAuth authorization, and plugin use.

Contact

Email [email protected] . Include the feature you were using, the relevant HCID or HRID when applicable, and a concise description of the problem. Never send passwords, AI Keys, OAuth access or refresh tokens, MFA codes, or other authentication secrets.

MCP and OAuth

The public MCP endpoint is https://huagongshe.com/mcp . Public tools can be used anonymously. Private records and write actions use account authorization. Compatible MCP clients can use the standard HGS OAuth flow; existing HGS AI Keys remain available for supported manual integrations.

If an OAuth connection is rejected, reconnect through the client and confirm the requested scope. Huagongshe OAuth scopes in HGS v1.7.0 are read, reaction:write, and skill:write. Notes are not exposed through MCP in this version.

Data corrections

For a chemical identity or reaction-data problem, include the HCID/HRID and the conflicting source evidence. Huagongshe intentionally fails closed on ambiguous or conflicting identity evidence rather than silently merging records.

Privacy and account requests

Use the same support address for account or data deletion requests and privacy questions. Do not include credentials in the request.
