Paste one prompt into Claude with LeadOcean connected and size your agency procurement manager list before you spend a single record. Connect the server at https://api.leadocean.io/mcp first. Setup is on the MCP page.
The prompt
Find procurement managers at marketing and advertising agencies in the United States.
1. Call leadocean_list_enum_values for industry and pick the marketing
and advertising agency values.
2. Call leadocean_count_leads with title Procurement Manager,
jobLevel Manager, those industries and country US.
3. Tell me the count and the filters you used.
4. Do not call leadocean_search_leads until I say go.What it resolves to
| Filter | Value |
|---|---|
| title | Procurement Manager |
| jobLevel | Manager |
| industry | Advertising Services, Marketing Services, Marketing and Advertising |
| country | US |
"Agency" is not an industry value, so the prompt maps it to the three marketing and advertising strings. Enum values are exact strings, which is why step 1 looks them up. Title and jobLevel are set together so Claude does not guess a seniority.
How many match
66 mailable people matched on 2 October 2026. Filters: title Procurement Manager, jobLevel Manager, industry Advertising Services, Marketing Services or Marketing and Advertising, country US.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. The facets show 42 sit under Advertising Services and 17 at companies with 10001+ employees. Procurement is a thin role at agencies, so widen the title before you conclude the list is small. The first variation below does that.
What you get back
Search rows carry the fields below, plus name, email status and company domain. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| Procurement Manager | 10001+ | Advertising Services | US |
| Procurement Manager | 51-200 | Marketing Services | US |
| Procurement Manager | 1-10 | Marketing and Advertising | US |
Variations
- Add the titles "Purchasing Manager" and "Sourcing Manager", keep jobLevel Manager and count again.
- Swap the title for "Director of Procurement" and jobLevel Director to reach heads of procurement at the larger networks.
- Change country to GB and ask Claude to count again before searching.
