Community Gmail server with auto-auth: search, read and send email via MCP.
Nothing to run from here
BounceBan MCP by usefulapi is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

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 mcp add --scope user --transport http bounceban-mcp-by-usefulapi https://bounceban.usefulapi.io/mcpReconnect, 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.
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
6 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.
Read verification credit balance and account rate limits without starting verification. Limits and credit balance are shared across the account's API keys.
No parameter schema on file.
Verify one email in regular mode. Costs verification credits on each request, including repeats, and requires confirm:true. Uses the standard API's 15-second result window; returns a final result or a queue/verifying task ID. Read that existing ID with bounceban_single_status later. Never resubmit simply because it is still pending. Basic-only mode can return unknown with score -1 for catch-all/SE
| Parameter | Type | Required | Notes |
|---|---|---|---|
| string | yes | — | |
| disable_catchall_verify | boolean | no | — |
| confirm | boolean | no | — |
Read an existing single verification ID without spending verification credits. Returns success, verifying or queue. Honor try_again_at when provided; poll no more than 10 times for an ID within 5 minutes, then stop. Results remain available for 90 days. This tool never starts another verification.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | — |
Submit 1–1,000 emails for regular-mode asynchronous verification. Starts a task and can consume verification credits; requires confirm:true. Check the dashboard before resubmitting after a lost/invalid response. greylisting_bypass:auto balances speed and accuracy; speed may yield more risky results; robust waits longer. No callbacks or automatic polling are configured.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| emails | array | yes | — |
| name | string | no | — |
| greylisting_bypass | string | no | — |
| disable_catchall_verify | boolean | no | — |
| confirm | boolean | no | — |
Read progress and aggregate results of an existing bulk task. Does not start verification. Wait between polls and honor account rate limits. importing/verifying status is still pending; finished means the task has ended.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | — |
Read up to 100 existing email results and a cursor for the next page. Results are retained for 90 days. No verification is started and no following page is fetched automatically. Omit state to get all processed results while a task is running; filtering by state can omit in-progress results. A pending response means wait and check the existing task later.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | — |
| cursor | string | no | — |

ATool-list grade · score 93 / 100
Release 1.9.0 · scanned 12 Nov 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 93
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| 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.

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.
flow-1
Untrusted input can drive an external action even though no sensitive source is exposed.

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.

Any signed-in account that does not publish BounceBan MCP by usefulapi can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
