Lists the email addresses Hunter has found for a domain, with names, positions, confidence and the address pattern

Run

TerminalAgent

Through ot mcp, an agent calls run_tool with this; ot asks you before anything that goes online or touches a target. Set it up: ot mcp install claude (or cursor, vscode, codex, gemini).

{"tool":"osintverse-community/hunter-domain-search","target":"example.com","input_type":"domain"}

Or just say: "Run osintverse-community/hunter-domain-search on example.com with OTInstaller." The registry's read-only MCP server at api.otinstaller.com/mcp can find tools without installing anything.

ot run osintverse-community/hunter-domain-search d:example.com --format table

ot install osintverse-community/hunter-domain-search

Docker image in a read-only container · talks to api.hunter.io · needs HUNTER_API_KEY · up to 1 min. The first ot run installs the tool after asking once. The example value is the registry's own test input, so this command has run. Drop --format table for JSON.

hunter-domain-search

Lists the email addresses Hunter has found for a domain. Each address comes with its owner's name, position, department and seniority, whether it is a personal or generic address, Hunter's confidence score and verification status, any LinkedIn, X or phone details Hunter has, and the pages it was seen on. The organisation behind the domain is reported with its usual address pattern (such as {first}.{last}). Uses the pyhunter client for Hunter's API. Only Hunter's database is read, so nobody at the domain is contacted.

ot run osintverse-community/hunter-domain-search --domain example.com

Inputs

Input	Required
`domain`	yes
`limit`	no	Most addresses to return: 10 by default, which is what free plans get; paid plans allow up to 100

Keys

HUNTER_API_KEY, set with ot keys set HUNTER_API_KEY. A free Hunter account includes a monthly allowance of searches: https://hunter.io/api-keys. Without the key the tool exits with code 3.

Notes

The results are people's work addresses, so ot and agents treat a run as collecting personal data and ask before running it. Hunter's confidence score becomes the entity's confidence: high from 90, medium from 50.

Next steps

Check an address with osintverse-community/holehe, or look the organisation up in osintverse-community/companies-house or osintverse-community/gleif.

Development

pip install pyhunter==2.1.0
python -m unittest
