Password Breach Checker

What it grounds

Password Breach Checker tells you whether a password appears in the Pwned Passwords corpus of passwords exposed in data breaches. Send the password or its SHA-1 hash and get a breached flag. Paid plans add how many times it was seen and a risk level.

Ways to ground with it

Ground answers in real data

Enable Password Breach Checker and it becomes a tool your agent calls over MCP to check itself against live data before it answers — grounding the response instead of guessing.

On the same endpoint and key

Password Breach Checker rides the one VerveContext MCP endpoint alongside 300+ other sources, so adding it to an agent is a toggle, not an integration.

Traceable and current

The agent pulls password breach checker at answer time and can carry the source with the result, so the reasoning stays current and auditable.

Connect over MCP

Point your agent framework at the VerveContext endpoint. Every enabled source — this one included — becomes a tool the model can call. No per-source plumbing.

How to ground an agent in it over MCP.

How do I give my agent Password Breach Checker?

Enable it on VerveContext and point your agent framework at the VerveContext MCP endpoint. Password Breach Checker then appears to the model as a tool named passwordbreach, which it calls when a task needs it — no per-source plumbing.

Which agents and frameworks can use it?

Any MCP client — Claude, Cursor, LangChain, and custom agents all speak the Model Context Protocol. Password Breach Checker is exposed as a standard tool, so nothing source-specific is required.

Can the agent cite Password Breach Checker?

Password Breach Checker is a capability rather than a factual source, so it isn't something to "cite" — but it runs on the same real-data layer, over the same MCP endpoint and key as every grounding source.

How many credits does a Password Breach Checker call cost?

Each call costs 5 credits. Scoped keys let you grant an agent only the sources it should reach, and usage logs show exactly what was pulled to ground each answer.

How current is the data?

Password Breach Checker is served live from APIVerve's production data engine and pulled at the moment the agent calls it, so answers reflect the world now rather than the model's training cutoff.

Where does the data come from, and what shows on my bill?

VerveContext runs on APIVerve, our production data engine; Password Breach Checker is one of 300+ sources on the same key. Invoices and card statements show APIVERVE.
