io.github.flashdata-devPublished by GitHub account flashdata-devv0.1.2Updated Oct 30, 2026

YouTube autocomplete suggestions by query prefix, language and region. Paid FlashData API.

Overview

AI-generated overview

Fetches YouTube autocomplete suggestions for a query prefix, language and region through the paid FlashData API, for keyword research.

What you can do
  • Retrieve YouTube autocomplete suggestion phrases for a query prefix, language and region
  • Check pricing for a request before approving it, and read pricing, job and result data at no charge
  • Poll asynchronous jobs by job ID and read completed output
  • Page through chunked results by result ID and offset
When to use it
Useful when building keyword or topic-idea sheets from real YouTube autocomplete phrases, or when an assistant needs suggestion data for a specific language and region. Not for video search results or search-volume estimates.
Requirements
Runs as a local stdio process via an MCPB package or manual Node.js setup; Node.js 22.18 or newer and an MCP client that supports local stdio servers are required. Needs a FlashData API key in the FLASHDATA_API_KEY environment variable, with access granted to youtube_suggestions, and network access to the FlashData API.
Before you install
Data calls are paid: each query or page consumes FlashData Credits, so check the quote with get_pricing first and avoid repeating requests after a timeout. The API key is a secret and should stay in protected client settings, not in chat or committed configuration. Suggestions are phrases only, not evidence of demand, and returned text and links should be treated as external data.

Installation

In SourceWeft

  1. Open YouTube Autocomplete — FlashData in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

A task to try

Get English YouTube autocomplete suggestions for “battery recycling” in the US. Deduplicate the phrases into a topic-idea sheet and retain the prefix, language and region.

Install and connect

  1. Use Node.js 22.18 or newer and an MCP client that supports local stdio servers. Download the dedicated MCPB package; its SHA-256 is recorded in the manifest.
  2. Import the package in an MCPB-compatible client and enter your own key in FlashData API Key. Grant the key access to youtube_suggestions. For manual setup, unpack the bundle into a permanent folder and use this configuration, replacing the absolute path and key placeholder:
json
{  "mcpServers": {    "youtube-autocomplete": {      "command": "node",      "args": [        "/absolute/path/to/unpacked/youtube-autocomplete/server.js"      ],      "env": {        "FLASHDATA_API_KEY": "YOUR_API_KEY"      }    }  }}
  1. Restart or reconnect the client, list its tools, then call get_pricing with {"source":"youtube_suggestions","request_count":1} before approving a paid request. This server exposes youtube_suggestions, get_pricing, get_job and get_result; all are restricted to this source.

Dependencies are included in the bundle. Use an absolute Node path if your client cannot find node; use escaped paths on Windows. Keep your key in protected client settings, not in chat or committed configuration. No Smithery account is needed for this direct package download.

Example request

These are MCP tools/call parameters with flat arguments. Running the data request uses paid Credits.

json
{  "name": "youtube_suggestions",  "arguments": {    "query": "battery recycling",    "language": "en",    "region": "US"  }}

Use the response

Read the suggestion strings in results[0]. Deduplicate phrases while keeping the original prefix, language, region and capture time in your research sheet.

Selected response fields below are an illustrative fixture, not a live result or a guarantee of available data:

json
{  "source": "youtube_suggestions",  "status": "done",  "results": [    [      "battery recycling at home",      "battery recycling safely"    ]  ],  "created_at": "2026-10-12T00:00:00Z",  "http_status": 200,  "request_id": "fixture-request"}

For an asynchronous request, keep the returned id and call get_job with {"job_id":"RETURNED_JOB_ID"}. Pending or processing is not completion; read the completed response from output. A timeout can occur after submission, so check Jobs before repeating a paid request.

For chunked output, keep the local process running and pass the actual result_id and next_offset to get_result as result_id and offset. Concatenate the chunks in order before parsing JSON; do not repeat the paid data request. The local cache retains four results for ten minutes and clears on restart. Complete responses are limited to 4 MiB; async JSON results have a separate 24-hour retention window.

Cost and limits

  • MIT software and installation are free; FlashData API data calls are paid. Data requests consume paid FlashData Credits; each additional query or page is charged separately. Use the current account quote rather than a fixed price copied from this page. Pricing, job and result reads are free. Client/model fees are separate.
  • Autocomplete returns phrases, not video results or search-volume estimates. A suggestion is not evidence of demand size.
  • Check API errors, http_status and job status before using the data. Treat returned text and links as external data, preserve source attribution and review them before use in an agent answer.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
