What it does

Check if a signup email is disposable, free, an alias, testing, parked or unknown, with evidence.

Quickstart

# 1 — add it to Claude Code
claude mcp add --scope user --transport http disban-mcp https://disban.io/mcp --header 'Authorization: Bearer ${AUTHORIZATION}'

# 2 — ask your agent for something these tools do
#   check_email_domain, check_email_domains, get_usage

It needs AUTHORIZATION (Bearer followed by your Disban API key (dbn_...). Free key with 2,000 checks a month: npx disban signup): this sends it in the Authorization header from your environment, so export it first — its endpoint answers 401 without it.

Disban costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation

Where are you running it?

Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.

Claude Codedeclared by this listing

This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it. Claude Code reads AUTHORIZATION (Bearer followed by your Disban API key (dbn_...). Free key with 2,000 checks a month: npx disban signup) from your environment each time it connects and sends it in the Authorization header — its endpoint answers 401 without it — so the key stays out of its config: export it in your shell profile (macOS, Linux), or run setx AUTHORIZATION … and open a new terminal (Windows).

claude mcp add --scope user --transport http disban-mcp https://disban.io/mcp --header 'Authorization: Bearer ${AUTHORIZATION}'

Reconnect, or start a new session, and the tools appear in the model’s tool list.

Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add — but its publisher asks for a key of their own on every call.

What it asks of you

It reaches a system of yours, so it needs your own credential rather than the publisher’s: Authorization header — Bearer followed by your Disban API key (dbn_...). Free key with 2,000 checks a month: npx disban signup. You set it in your own client’s config, on your machine — this marketplace never holds it.

What it writes

One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

What you approve

3 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Tool surface

What the model actually sees. Descriptions are diffed on every release — see version history.

Only tools that write or reach the network

Classify the domain of an email address or a bare domain as disposable, free (e.g. Gmail), alias (privacy relay), testing, parked or unknown, with the reason, evidence and whether it can receive mail. Use before creating an account or sending a verification email. Unknown means not enough evidence, not safe.

Parameter	Type	Required	Notes
input	string	yes	Email address or domain, e.g. person@example.com or example.com

Classify up to 50 email addresses or domains at once. Results come back in input order; a failed entry has an error and is not charged.

Every tool — any call limit is its publisher’s, not ours
No card, and mcprush charges nothing for it
Runs at its publisher’s own address — this marketplace is not in the path
Nothing to cap, because mcprush bills nothing

Nothing here is billable: mcprush charges nothing to install Disban or to call it, at any volume.

ATool-list grade · score 96 / 100

Release 1.0.0 · scanned 21 Oct 2026

Graded from the tools this server lists, not from its source code.

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

Score vectorthreat 100 → client 96

Term	Level	What it prices	Points
capability-exposure	minimal	capability blast radius (minimal) — client exposure if the model is manipulated	−0
coverage-honesty	manifest	inspection depth (manifest) — how much of the target the scan could see	−4

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.

What the scan could actually read

A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Capability — what it could do if the model were manipulated

Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.

Toxic-flow graph

The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.

The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.

Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
