Help us keep the directory useful

The best way to reach Mengbi is by email at [email protected]. Please include the page URL, the specific claim or behavior you are reporting, and a link to any public evidence that helps us reproduce it. Messages about a tool profile, source attribution, accessibility problem, or broken link are welcome. We review corrections against the public source and record changes in the profile history when appropriate.

For privacy questions, explain what information you believe is involved and whether you are asking for access, correction, or deletion. Do not send passwords, API keys, authentication cookies, payment details, or other secrets by email. Mengbi will never ask you to paste a credential into a support message. If a report contains personal information, share only the minimum detail needed to identify the page or record.

Developers and agent builders can start with the developer resource index, the OpenAPI specification, or the MCP manifest. These resources describe read-only discovery interfaces. They do not grant access to private accounts, administration features, upstream provider credentials, or unpublished crawler data.

Partnership and press requests should describe the proposed audience, the exact page or product being discussed, and any deadline. Inclusion in the directory is based on evidence and fit for a real use case; paid placement does not change quality labels or source requirements. We aim to reply with a clear next step, even when the answer is that a request is out of scope.
