PostLink

Ask anything about any YouTube video

Comments and transcripts as clean data — in your dashboard, over the REST API, or in your agent through MCP. Replies drafted for one-click approval.

How a run works

  1. Step 1Point it at a videoPaste a URL or channel. PostLink pulls the comments and the transcript — no OAuth dance, no scraping on your side.
  2. Step 2Get clean dataThe same call works from the dashboard, the REST API, or MCP. Every tab maps 1:1 to an endpoint.
  3. Step 3Let the agent workAsk questions, get charts, queue drafted replies. AI runs only where you point it — and only with your approval.

Built to be called, not clicked

The dashboard is interactive documentation. Ship the same calls from your backend, or hand the whole toolbox to an agent with one line of MCP config.

curl https://postlinkapp.com/api/v1/comments \
  -H "Authorization: Bearer pl_live_…" \
  -d video=yt_9kF3xB2 -d limit=50

"mcpServers": {
  "postlink": { "url": "https://postlinkapp.com/mcp" }
}

Replies drafted, never sent alone

The agent reads the thread, matches your voice, and queues a draft. Nothing leaves PostLink without your click.

Next.js and Postgres, same as before — the rebuild was about deleting code, not swapping it. Full cost breakdown drops Friday, it's already pinned.

Questions

What is PostLink?
PostLink turns YouTube comments and transcripts into structured data you can pull from a dashboard, a REST API, or an MCP server — plus an agent layer that analyzes threads and drafts replies for your approval.
How does the MCP server work?
Point your agent at the PostLink MCP endpoint with your API key and it gets the same tools the dashboard has: fetch comments, fetch transcripts, run analyses. Every dashboard tab maps 1:1 to an endpoint.
What counts as a run?
One run is one fetch-backed execution — a video’s comments, a transcript, a tag lookup — whether it comes from the dashboard or the API. AI analyses are metered separately as credits, because inference costs more than fetching.
Are the free tools actually free?
Yes. Every tool that costs us nothing to run is unlimited for everyone. Runs are only metered where we pay per call: fetching comments, transcripts, and API usage.
