OpinionPulse + Claude: turn an opinion-shift signal into a short briefing memo

Key takeaways

The short version.

  • OpinionPulse reports a shift when a recent poll headline and overlapping Polymarket and Kalshi prices point the same way, and it links every source.
  • Claude can add OpinionPulse as a custom connector using its remote MCP address, and its connector settings accept a fixed key as a request header.
  • Claude writes the memo. OpinionPulse supplies the signal and the sources. You check the sources and decide what to do.
  • Nothing here is a listing or built-in integration with Claude. You add the address yourself.
  • Both tools report public data. Neither gives advice, makes a trade or tells you how anyone will vote.

  • One finds out whether something moved.

It is for people who have to tell others what public opinion is doing, in a few lines and with sources: campaign staff, newsroom editors and reporters, communications and public affairs teams, advocacy groups, newsletter writers and students.

OpinionPulse watches three public signals for a topic you name: poll headlines from Google News, prices on Polymarket and Kalshi, and post volume from the official X API. When a recent poll and the overlapping market prices point the same way, it reports a shift with its direction and links. Claude is Anthropic's AI assistant, and it is good at turning raw material into clear, short writing.

One finds out whether something moved. The other helps you explain it to the people who need to know.

Use cases

5 ways people use OpinionPulse + Claude.

  1. Briefing memo

    1. Write the morning briefing memo

    Ask Claude, through the connector, whether opinion is moving on the topics you follow. OpinionPulse returns the result for each topic: a shift with a direction, or a code that says why there is none. Then ask Claude for a memo of five lines or fewer: what moved, which sources say so, and what is still unknown.

    Because every source is attached, the memo can name them. A reader who doubts a line can open the poll or the market page and check it.

  2. Same facts, new tone

    2. Tailor one signal to different readers

    A campaign manager, a newsroom editor and a spokesperson want different things from the same signal. Give Claude the result and ask for a three-line note for each, keeping the facts identical and changing only what each reader needs to know.

    Tell Claude to leave out anything the result does not say. The memo should describe what the sources show, not predict how people will vote.

  3. No shift

    3. Explain a missing signal honestly

    When the signals do not line up, OpinionPulse does not guess. It returns a code, for example that no poll was found in the window, and a missing value is never shown as zero.

    That is useful in a memo too. Ask Claude to write a plain line such as: no shift reported, no recent poll found, check again after the next release. Saying what you do not know is better than filling the gap.

  4. Your context

    4. Add context from your own notes

    OpinionPulse knows polls, prices and X volume. It does not know your district, your coverage plan or last week's talking points. Paste those into the chat, or attach the file, and ask Claude to connect the signal to them.

    Keep the two kinds of material apart in the memo, with the sourced signal in one part and your own judgment in another, so readers can tell which is which.

  5. Volume spike

    5. Know what the X volume label means

    OpinionPulse also gives an X post-volume label with a spike flag. It tells you that people are talking more, not what they think. Ask Claude to mention it as context and not as proof of a shift.

    A good memo says plainly that volume measures attention. Whether the attention is for or against something is a separate question that this label does not answer.

How to

How do I connect OpinionPulse to Claude?

  1. Step 1

    Open [opinionpulse.app](https://opinionpulse.app), get your free API key and save it, because it is shown once. The remote MCP address is https://opinionpulse.app/mcp.

  2. Step 2

    In Claude, go to Customize, then Connectors, and choose to add a custom connector. Enter a name and that address, then review the authentication settings Claude detects. For a fixed key, the settings let you add a request header, as the site describes.

  3. Step 3

    On a Team or Enterprise plan an organization owner adds the connector first, then each member connects.

  4. Step 4

    Start a chat, name a topic and ask whether opinion is shifting. Review the tool requests Claude shows before you approve them, then ask for your memo.

Custom connectors are described in Anthropic's help center. Plans and menus can change, so follow that page. OpinionPulse is not listed in Claude's directory or built into Claude.

FAQ

Frequently asked questions.

Is OpinionPulse an official Claude integration?

No. There is no partnership or built-in integration. Claude supports custom connectors through remote MCP, and you add the app's address yourself. The app is an AgentStructure.AI app.

Does OpinionPulse tell me how people will vote?

No. It reports public data from polls, prediction markets and X volume. It is not financial or political advice, a trade recommendation or a prediction of how people will vote.

Can Claude be trusted to summarize it correctly?

Check the memo against the attached sources before you share it. Ask Claude to use only what the result says, and correct anything it adds.

What does it cost?

Asking about any topic works with a free key through the API or MCP. Alerts when opinion shifts on topics you follow are the Premium part, and the apps are free during the beta, so check the site for the current status.

What if there is no shift?

OpinionPulse returns a code that says why, such as no poll in the window, and never shows a missing value as zero. Your memo can say the same.
