## MCP tools (5)

### `package_vulnerabilities` (~100 tokens)

## Common questions

### What is the Ambolt MCP server?

Ambolt is an MCP server listed in the public MCP registry as dev.ambolt/ambolt. Company registers, financials, funding rounds, tenders and industry codes. Sourced and dated. This page covers its npm package (@ambolt/mcp).

### Is the Ambolt MCP server safe to use?

Ambolt scores 70 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 17 October 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Ambolt MCP server expose?

Ambolt exposes 5 tools: disposable_email_check, dns_lookup, fx_rate_ecb, iban_validate, package_vulnerabilities. Their descriptions and schemas cost roughly 430 tokens of context every time the server is loaded.

### Is the Ambolt MCP server still maintained?

Ambolt is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Ambolt MCP server under?

Ambolt declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
