Opsis OSINT

Opsis MCP Server

OSINT search for Claude, ChatGPT and any AI agent. Give your assistant email, username and domain search across 1,000+ sources. It finds the accounts behind an identifier, reads the profiles, and follows the leads.

• Hosted: https://api.useopsis.com/mcp (Streamable HTTP). Nothing to install.
• Sign in with your Opsis account (OAuth). No keys to copy.
• 3 free searches on every account, no card.
• Verified results: an account only counts when the site returns real profile evidence. Our last run of 1,000+ modules had zero false positives against known fake accounts.

Tools

Tool	What it does	Cost
search_email	Find the accounts registered to an email address, with names, photos, bios, locations, stats and linked accounts	1 credit
search_username	Find accounts that use a username across 1,000+ sites. premium adds solver-protected sources	1 credit (premium 2)

get_search	Read a search that was still running	Free
list_searches	Your recent searches	Free

A full search checks 1,000+ sources live and takes 60 to 110 seconds. Search tools return what is ready after about 45 seconds plus a run_id, and get_search returns the rest, so nothing is lost to client timeouts.

Example prompts

• "Who is behind [email protected]? Check which sites the address is registered on."
• "Search the username jdraper01 and summarize the profiles that look like the same person."
• "This phishing email came from [email protected]. Look up the domain and the sender."
• "List the websites and other accounts linked from the profiles you found, and search the strongest ones."

Pricing

Every account gets 3 free standard searches through the MCP server. After that, searches use API credits on a Pro plan: top-ups start at $20 for 50 credits and reach $0.25 per credit at 1,000. Reading results, listing searches and checking your account are always free. Plans and credits.

Privacy and acceptable use

• Public sources only: public profile pages, public APIs and registration checks. No breach databases.
• Silent: Opsis never logs in to anyone's account and never contacts or notifies the person you search.
• Opt-out respected: every search goes through the Opsis opt-out list and rate limits.
• Lawful use: use Opsis for investigations you are authorized to carry out. It is not for employment, tenant or credit-eligibility screening. See the terms and privacy policy.
