Brave Search MCP Server: web results, images, videos, rich results, AI summaries, and more.
Nothing to run from here
YouTube Captions — FlashData 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. This one runs on your machine: your client starts YouTube Captions — FlashData as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.

Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Submit Google and YouTube queries, including downloads to customer storage, as background jobs. Each queries entry uses source plus that source’s flat tool arguments, without mode or a params wrapper. Returns an id for each query; use get_job to read it. Each query consumes Credits; downloads…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| queries | array | yes | — |
Read job.status and Credits usage using its id. Pending/processing means the job is still running. Completed jobs include the original response in output. For YouTube downloads, output.results[0] contains file_url and file_size in customer storage. Private files require that storage’s access…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| job_id | string | yes | — |
Read the next JSON text chunk of a large tool result, without repeating the paid query. Use result_id and next_offset from the previous response, with the same API Key. Concatenate chunks in offset order before parsing JSON. Cached results expire after 10 minutes; only the four newest large…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| result_id | yes | — | |
| offset | integer | no | Position in UTF-16 code units. Use next_offset from the preceding chunk. |
| limit | integer | no | Maximum UTF-16 code units to return, not a row or byte count. |
Read the live account-wide available Credits balance shared by all API keys. Free; does not reserve or spend Credits.

ATrust score 99 / 100
Release 0.1.2 · scanned 28 Oct 2026
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 = 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.
Tool surfacenot available
Implementation sourceread
Package metadataread
Live transportnot available
No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
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.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| No per-tool rows for this release — see the note below. | ||
No tool surface was enumerated, so there is nothing to attribute a capability 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.
Release history
It installs from its repository rather than from a versioned package, so the command cannot be pinned to a release. The history below is for reading; the current release on file is 0.1.2.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish YouTube Captions — FlashData 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.
