pdata Prediction Markets is an MCP server with 14 tools an agent can call, among them closing_soon, get_event, get_event_similar. It answers at https://api.pdata.world/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Polymarket, Kalshi + 6 more prediction markets: live odds, volume, movers. Read-only, no auth.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
closing_soon | Use when the user wants to see markets that will resolve within the next 36 hours. Returns markets sorted by close timestamp ascending. Filterable by `source=` and `categories=` (CSV). Excludes Limitless and price-derivative markets. Inputs: limit, spread_min, spread_max, probability_min, probability_max, prob_24h_change_min |
get_event | Use when an agent needs the full detail of a single prediction-market event by its composite key (source + event_id). Returns the event with all of its child markets, latest probabilities, and metadata. The canonical URL `https://pdata.worl Inputs: source, event_id |
get_event_similar | Use when an agent needs events similar to a given event — cross-platform equivalents and topically-related markets, precomputed nightly from title embeddings. Best-first; empty list (never an error) when no similarities are known yet. Inputs: source, event_id, limit |
get_market | Use when an agent needs the full detail of a single market by its composite key (source + market_id). Returns the market with its parent event reference, current probability, volume, 24h delta, and historical chart points. Includes a `_meta Inputs: source, market_id |
get_summary | Use when an agent needs platform-level context before drilling into individual markets: one row per platform (Polymarket, Kalshi, Manifold, Myriad, Limitless, Predict, Opinion, Gemini) carrying 24h notional volume, active event and market c |
list_countries | Use when an agent needs the list of country tags that markets have been tagged with. Returns the canonical country vocabulary with per-country market counts. Accepts the same filter params as `list_markets` (source, category, status, volume Inputs: spread_min, spread_max, probability_min, probability_max, prob_24h_change_min, prob_24h_change_max |
list_events | Use when an agent wants to browse, filter, or search prediction-market events across all 8 platforms. Returns paginated events with their child markets, prices, and platform metadata. Filterable by source (polymarket/kalshi/manifold/myriad/ Inputs: page, page_size, source, active, closed, volume_24hr_min |
list_markets | Use when the user wants to browse, filter, or sort individual markets (not events). Returns paginated markets with their probability, volume, source, parent event ID, and 24h delta. Filterable by source, country, category, status, and full- Inputs: page, page_size, spread_min, spread_max, probability_min, probability_max |
list_news_movers | Use when the user wants to see the news-feed view: markets that exhibited a probability spike in the chosen lookback window, scored by `|Δprob_pp| × log10(1+USD-equivalent volume)`. Refreshed every 5 min. The `window=` param selects the loo Inputs: source, categories, q, min_score, include_entertainment, include_microprediction |
map_heat | Use when you need a geographic snapshot of where prediction-market attention is concentrated. Returns per-country heat (capped news score, summed) for the current moment (`at=now`) or a past hour (`at=<ISO8601>`). Inputs: at, source |
map_timeline | Use when you need the hourly total-heat time series that drives the /map playback scrubber. History accretes from launch (no backfill). Inputs: source |
news_movers_by_category | Use when the user wants the news feed bucketed by category. Returns the same data shape as `list_news_movers` but pre-grouped into the canonical 14-category vocabulary, with cluster grouping inside each bucket. Useful for 'what's moving in Inputs: source, q, min_score, include_entertainment, include_microprediction, include_crypto |
search_suggest | Use when an agent has a name or phrase and needs the `(source, id)` of the matching event or market before calling another tool. Resolves free text against events AND markets in one call, best-first, and reports `total_events` / `total_mark Inputs: q, limit |
top_movers | Use when the user wants to see markets with the largest 24h probability swings. Returns the top N movers (default 5, max 20) ranked by absolute `prob_24h_change`. Filterable by source. Excludes Limitless and price-derivative markets by cura Inputs: limit, spread_min, spread_max, probability_min, probability_max, prob_24h_change_min |

It answered our last check on 24 October 2026 in 187 ms. Over 6 checks since 12 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by pdata.world and served from api.pdata.world, the vendor's own domain: https://api.pdata.world/mcp.
14, as returned by the server's own tools/list on 23 September 2026: closing_soon, get_event, get_event_similar, get_market, get_summary, list_countries, list_events, list_markets, and 6 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.pdata.world/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: world.pdata. Endpoint host: api.pdata.world. ARD identifier: urn:air:world.pdata:mcp:mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
