What the assistant can call

Once Dnsdumpster is connected, these are the calls the assistant has available:

• Features — The Features tool exposed by this server

Setting it up

dnsdumpster on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Dnsdumpster's toolset — Features — is a fair guide to whether it matches your workflow. It is maintained by Paul Sec; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the dnsdumpster mcp server does with a few real requests.
