September 2026
September 22, 2026 - [Update] State filter accepts full names and abbreviations
The
statefilter onsearch_peopleandsearch_companiesnow accepts a full state name or its abbreviation, so"Texas"and"TX"both work. exclude_state accepts the same values. Lists can mix both forms, for example state:["Texas", "FL"]. All other location filters still need exact full names, including country and city.
September 22, 2026 - [Update] Positive filters on search_people and search_companies now accept lists
Every positive filter now accepts a list of values, matching how
exclude_*filters already worked. A list is OR within its field, AND across fields, sotitle: ["CEO", "CMO"]withcountry: ["United States", "Canada"]returns (CEO or CMO) in (US or Canada) as one ranked search instead of several separate ones.
September 21, 2026 - [Update] Documentation for ChatGPT, Grok, Cursor, and more
We've added documentation for connecting to the MoltSets MCP via: ChatGPT, Grok, Cursor, Windsurf, and any other MCP client.
September 18, 2026 - [Change] New personal email endpoints
We've added US-only versions of the two personal-email endpoints. The old endpoint names still work for now but are deprecated and will be removed — we'll announce the date in advance. Same data, same format — non-US records are now filtered out. To migrate, add
_usato the end of the tool or route name:linkedin_to_personal_email→linkedin_to_personal_email_usalinkedin_to_best_personal_email→linkedin_to_best_personal_email_usa
September 18, 2026 - [Fixed] Resolved personal-email lookup consistency issues across endpoints
All personal-email lookups now read from the same source. Previously the same LinkedIn URL could return an email from one endpoint and "not found" from another.
September 16, 2026 - [Update] API calls now require User-Agent
API calls now require
User-Agentto be added to theheaderin order for a successful call to be made. API connections created prior to September 16 will experience a 403 error untilUser-Agentis added to theheader. More information
September 15, 2026 - [Added] $397 mid-tier plan introduced
We've introduced a new mid-tier plan for $397 per month that has 10x the rate limits of the $97 plan. At the same time, the $997 plan's rate limits have also increased to be 15x those of the $97 plan.
September 11, 2026 - [Added] MCP now allows for native and CLI connections
The MoltSets MCP now accepts
http://redirect URIs for loopback addresses (127.0.0.1,::1,localhost), in line with RFC 8252 for native and CLI applications. Previously onlyhttpsredirect URIs were accepted, which made the connection unworkable for command-line tools that listen on a local port rather than hosting HTTPS. More information
September 11, 2026 - [Update] Search endpoint Fair Use accounting
search_business_email_by_name,search_linkedin_profile, andsearch_business_profile_by_namenow correctly count against the search Fair Use Policy (FUP) limit, consistent with other search endpoints. Usage from these endpoints was previously not being counted, which has been corrected.
September 10, 2026 - [Fix] Fixed SMS sign-up/login issue
Fixed the issue with SMS sign-up and login whereby users were not receiving the SMS containing their access code. SMS sign-up remains restricted to North American numbers at this time.
September 9, 2026 - [Update] No-result lookups now return 200, not 404
No-result lookups now return
200withstatus: "not_found"and full metadata instead of a404, on both single and batch calls;404is reserved solely fortool_not_found. MCP responses also gain a one-line note clarifying that a miss is a normal, uncharged outcome rather than an error.
September 9, 2026 - [UX Update] 'Terminal' input prompt changes
Renamed the dashboard's "Ask me anything about MoltSets" input prompt to "Learn more about MoltSets — type /help to get started," since the original text referenced a sidebar prompt list that's since been removed and left users unsure how to use the input.
September 9, 2026 - [Removed] UGC program will not be launching
The UGC program previously mentioned in the MoltSets app will not be launching. We had originally planned to introduce it once the beta period ended, but we've since decided against it. The program never became active.
