Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
A U.S. voter's ballot by address, with an exact quote and source behind every candidate position.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
list_issuesThe 18 issues Plain Ballot tracks. Each has two sides, each worded the way its own supporters would say it. Use the short side labels ("l" and "r") when giving priorities to score_fit.
get_ballotEvery researched race on the ballot for a U.S. street address, with each choice's position on the issues that office decides, the exact quote, and the source URL.
score_fitHow closely each choice on the voter's ballot fits the priorities the voter stated, from 0 to 100. Plain arithmetic, the same as plainballot.com: issues where a choice has no sourced position are left out, never guessed. Only use priorities the voter actually gave you.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Every race on your ballot, matched to what you care about. Every position backed by a quote you can check.
plainballot.com · How it works · The open data · Contribute
Who's running, and where do they stand? Pick the issues you care about, set a dial for each, and enter your address. Plain Ballot goes through your ballot and shows who fits you, why, and where that came from. Party labels stay hidden until you ask. No ads, no account, and your address isn’t stored.
Covering every race in California, plus U.S. House and Senate races in all 50 states, for Nov 3, 2026.
Two projects, both free and open:
Chatbots get voting facts wrong. Plain Ballot is built so no single model's word ever reaches a voter.
The research is its own project: [Open Election Data](https://github.com/n8peace/open-election-data). It has a free, static API with no key needed:
curl -s https://n8peace.github.io/open-election-data/v1/divisions/ca/cd-10.json
Use it for anything, including commercial products, under the Open Database License: credit it, and share improvements to the data under the same terms.
Plain Ballot works without a browser. Point any AI agent that supports MCP (Claude, ChatGPT, Cursor and others) at:
https://plainballot.com/mcp
It has three read-only tools:
list_issues: the 18 issues and how each side is worded.get_ballot: every researched race for a street address, with each choice's position, the exact quote, and the source.score_fit: how closely each choice fits the priorities the voter gave, using the same arithmetic as the site. No model is involved.The agent is told the same rules the site follows: stay nonpartisan, quote and link sources, never fill in a missing position, and only score priorities the voter actually stated. Addresses aren't stored.
Prefer plain JSON? GET https://plainballot.com/api/ballot?address=... returns the same ballot, and the research itself is a free static API.
Good sources are already out there, and Plain Ballot learns from them:
What we couldn't find was a free, open dataset of where candidates stand, with a checkable quote behind every position, with every candidate on the same issues so they can be compared, and free for anyone to reuse. So we built one: Open Election Data. Every claim still comes from the candidate's own words: agents follow a summary back to the candidate's site, voting record or interview and quote that.
The research runs on your own Claude or ChatGPT plan, so anyone can add coverage without paying for API credits. It happens in Open Election Data, which has an open "research your state" issue for each state.
npm install
cp .env.example .env.local npm run dev # http://localhost:3000
Without keys, it runs on a fictional sample ballot and the dials still work. Researched races come from the open data's API (set ELECTION_DATA_DIR to a local checkout's data/positions to work offline). Keys turn on typed priorities (AI_GATEWAY_API_KEY), real ballot lookup (GOOGLE_CIVIC_API_KEY) and address suggestions (GOOGLE_PLACES_API_KEY).
npm test # matching, neutrality, sharing, abuse limits
npm run eval # does the AI put people on the right side of each dial? (calls the model) npm run check:issues # dial wording matches the research data
Next.js on Vercel. The Census geocoder finds a voter's districts. Researched races come from the Open Election Data API, matched to voters by district. BotID, rate limits and a spending cap protect the paid endpoints (docs/security.md). The full picture, with a diagram: docs/ARCHITECTURE.md. Coding with an AI agent? Point it at AGENTS.md.
