Storyflo MCP Server

Official Model Context Protocol server for Storyflo — curated audio news + daily briefings + the public Declassified library (FBI/CIA/NSA/NASA/DOJ/AARO releases) + market-linked story signals, all exposed as a callable surface for any LLM agent.

Claude Desktop one-click .mcpb: for a no-config Claude Desktop install, see the companion extension repo Alisammour/storyflo-mcp-extension.

This repository contains a zero-dependency stdio bridge (src/index.js) that relays MCP JSON-RPC between a local stdio client and the hosted streamable-http endpoint, plus discovery + install references. The Storyflo platform itself is proprietary; agent integration through the public API is the supported surface.

Install — one click

Claude Code: claude mcp add --transport http storyflo https://api.storyflo.com/mcp/v1 Any remote client: https://api.storyflo.com/mcp/v1 (streamable-http) · stdio: npx storyflo-mcp

The best tools are free + no-auth — try search_declassified (real FBI/CIA/NSA/NASA cases) in seconds, then earn revenue share by integrating via register_embedder.

Run the stdio bridge

npx storyflo-mcp            # or: node src/index.js

Or via Docker:

docker build -t storyflo-mcp .
docker run -i --rm storyflo-mcp

Environment variables:

Variable	Default	Purpose
STORYFLO_MCP_URL	https://api.storyflo.com/mcp/v1	Upstream MCP endpoint
STORYFLO_TOKEN	(unset)	OAuth bearer for tools/call; discovery (initialize, ping, tools/list, resources/list) works anonymously

Tools

Storyflo exposes 21 tools (20 free + 1 premium) across three auth tiers:

Public (no auth, no OAuth flow needed) — designed so any LLM agent can browse + recommend from a fresh client install without an OAuth handshake:

tool	what it does
search_articles	search the curated article corpus by query/vertical
get_article	fetch the full record + body text + audio URL by slug
get_audio_url	resolve the playable audio URL for an article
get_trending_topics	what's hot on Storyflo right now
get_personas	the host voices (Theo / Mason / Riley / Iris / Brock / Wit)
get_vertical_landscape	one-shot per-vertical context for onboarding a listener
list_podcasts	the full catalog of audio shows (per-host + Declassified)
digest	top-N articles aggregated across verticals for a window
get_market_linked_stories	stories matched to Kalshi event contracts (editorial, not advice)
get_crypto_market_link	Kraken affiliate markets link-out for crypto-relevant stories
search_declassified	substring search across the Declassified case archive
get_declassified_case	full Declassified case record by slug
digest_declassified	most-recently-published Declassified cases over a window
subscribe_topic	mint/update a personal podcast RSS feed scoped to verticals
subscribe_declassified_topic	resolve a Declassified podcast-feed URL (read-only)
list_subscriptions	list feeds this agent has minted for the human
register_embedder	returns a partner onboarding URL (no email/row created)
get_embedder_manifest	the embedder integration manifest
get_embedder_network_manifest	the embedder network manifest
quote_partnership	explore partnership tiers, creative formats + payout rails

Note: subscribe_topic, subscribe_declassified_topic, and list_subscriptions are listed as public for discovery; calls that mint/list a listener's feed resolve identity via OAuth bearer when present.

Premium (x402 over USDC on Base mainnet) — get_vertical_briefing: a stitched audio briefing of the top-25 trending articles in a vertical from the last 24h.

The live tool manifest (with full JSON Schema for every parameter) is at /v1/agents/openai-tools.json — the source of truth Glama, OpenAI, and Anthropic introspect.

Declassified library · public · no auth (NEW, 2026-06-20)

The Declassified library is Storyflo's narrated archive of publicly-released government documents from FBI, CIA, NSA, NASA, DOJ, AARO, war.gov, and other agencies. Every case has a narrated audio version, a transcript excerpt, and a source-document link. The 4 tools below traverse the same archive that backs the /declassified FE shelf and the public Declassified RSS feed.

search_declassified · public

Substring search across case title + synopsis. Returns {slug, title, dek, episode_date, duration_sec, agency, category, era, audio_url} per match.

Parameters: query (string, required), limit (int, 1-50, default 10).

get_declassified_case · public

Full case record by slug. Returns {slug, title, dek, summary, transcript_excerpt, episode_date, duration_sec, agency, category, era, cover_url, audio_url, source_doc_url, related_cases:[{slug, title}]}.

Parameters: slug (string, required).

digest_declassified · public

Most-recently-published cases over a rolling window. Returns the same card shape as search_declassified.

Parameters: window (today | week (default) | month), limit (int, 1-50, default 10).

subscribe_declassified_topic · public

Resolves a podcast-feed URL the user can paste into Apple Podcasts, Overcast, Pocket Casts, or Spotify to receive every new Declassified case automatically. Returns {topic, rss_feed_url, archive_url, episodes_url, matched_so_far, note}. Read-only by design: no DB row is written, no email is stored, the RSS feed IS the subscription.

Parameters: topic (string, required), email (string, optional — informational only, never stored).

search_articles · free

Search Storyflo's curated article corpus by query and/or vertical. Use this when the agent needs to find articles matching a topic before deciding which one to read or play.

Parameters

name	type	required	description
query	string	no	Full-text query against title + body + summary. Omit to browse a vertical without a keyword filter.
vertical	enum	no	One of: tech, finance, science, media, sports, culture. Narrows results to a single vertical.
limit	int	no	Max results (default 10, capped 25).

Returns — array of { slug, title, publisher, vertical, snippet, audio_url, listen_seconds, published_at }.

---

get_article · free

Fetch the full record for a single article by slug. Use after search_articles when the agent needs the full body text or full audio URL.

Parameters

name	type	required	description
slug	string	yes	Article slug, as returned by search_articles.

Returns — { slug, title, body_text, audio_url, publisher, vertical, sources[], published_at }.

---

get_audio_url · free

Resolve the playable audio URL for an article without fetching the body. Use when the agent wants to hand off audio playback to the user. Free tier returns a stitched-with-ad URL; Plus/Pro returns the bare audio.

Parameters

name	type	required	description
slug	string	yes	Article slug.

Returns — { slug, audio_url, listen_seconds, tier }.

---

subscribe_topic · free

Mint or update the human's personal Storyflo podcast feed. Pass 1–6 vertical slugs and the server creates a private RSS feed scoped to those verticals — or updates the existing feed in place if the listener already has one. Returns the RSS URL the listener can paste into Spotify, Apple Podcasts, Pocket Casts, or any podcast client.

Behavior

• Persistent server-side side-effect — a ListenerSubscription row is created or updated. The returned RSS URL stays stable across calls for the same listener (no re-pasting needed).
• Idempotent on identical input — calling twice with the same verticals leaves state unchanged.
• REPLACES on different input — calling with a different verticals set OVERWRITES the previous selection rather than adding to it. Use this to switch a listener's feed; do NOT call to add verticals incrementally. For additive behavior, read the current set via list_subscriptions first and pass the union.
• Single feed per listener — call list_subscriptions first to avoid clobbering an existing feed the listener explicitly chose.

Use when the agent has been asked to set up audio news for the human across a defined set of topics. Do NOT use to FETCH articles or audio — that's search_articles + get_audio_url.

Parameters

name	type	required	description
verticals	array<enum>	yes	1–6 unique slugs from tech, finance, science, media, sports, culture. Replaces (does not append to) the listener's current selection.

Returns — { feed_url, verticals, listener_token }.

---

list_subscriptions · free

Return the listener feeds this agent has minted on the human's behalf. Use before subscribe_topic to avoid creating duplicate feeds.

Parameters — none.

Returns — array of { feed_url, verticals, created_at }.

---

get_vertical_briefing · paid (x402)

Fetch a stitched audio briefing of the top-25 trending articles in a single vertical from the last 24h. Use when the agent wants a "today's headlines for X" experience for the user. Read-only — no listener state mutated.

Parameters

name	type	required	description
vertical	enum	yes	One of tech, finance, science, media, sports, culture, news.

Returns — { vertical, audio_url, item_count, listen_seconds, articles[] }.

Cost — single x402 charge; covers the full stitched briefing audio.

---

digest · free (heaviest)

Aggregate the top-N articles across one or more verticals for a window (24h / 7d / 30d). The heaviest action — counts most against per-agent rate limit. Use for "read me today's tech + finance news" prompts where the agent wants a curated cross-vertical roll-up rather than a single vertical's briefing.

Parameters

name	type	required	description
verticals	array	no	1–6 verticals. Defaults to all 6 if omitted.
window	enum	no	24h (default), 7d, or 30d.
limit	int	no	Max articles per vertical (default 5, capped 25).

Returns — { window, verticals, items: [{ slug, title, vertical, audio_url, snippet }] }.

---

get_market_linked_stories · free

Storyflo stories that match an actively traded event contract on Kalshi — a CFTC-regulated designated contract market. Each item carries qualitative signal tags plus a link-out to Kalshi's own page where the live market data lives.

This is an editorial sourcing surface, not market-data redistribution. Storyflo never returns raw prices, market-implied probabilities, volumes, or open interest in this payload. The agent or user follows the linkout to see live numbers on Kalshi.

Use when the agent needs to know which Storyflo stories are about news themes that have an actively traded event contract — e.g. World Cup matches, political mention contracts, corporate events. Same shape as a newsroom citing CME futures: market activity informs which stories are worth surfacing.

Parameters

name	type	required	description
vertical	string	no	Filter by story vertical (e.g. news, finance, tech, crypto).
category	string	no	Filter by Kalshi event category (e.g. Politics, Economics, Companies, Science and Technology, Sports).
signal	enum	no	One of active, high_velocity, genuine_uncertainty. high_velocity = the matched market is repricing meaningfully in the last 24h; genuine_uncertainty = the market sits in the 40–60% band where it itself is uncertain.
limit	int	no	Max items (default 10, capped 50).

Returns — array of:

{
  "story": { "slug", "title", "vertical", "published_at" },
  "matched_market": { "title", "category", "url" },
  "signal_tags": ["active", "high_velocity"?, "genuine_uncertainty"?],
  "match": { "score", "shared_terms" }
}

plus top-level attribution and disclaimer strings on every payload.

The matched_market.url links to Kalshi's own events page so the user / agent sees live market data on the source. Storyflo does not redistribute that data.

Compliance posture (counsel-reviewed; regression-tested in CI):

• Vocabulary locked: never bets, odds, picks, or wagers — anywhere on the surface
• Attribution on every payload: "Market data: Kalshi, a CFTC-regulated designated contract market"
• Disclaimer on every payload: market-implied probabilities are exchange prices, not Storyflo forecasts and not investment advice; story-to-market links indicate topical correlation, not causation; informational use only
• Liquidity floor (vol24h ≥ 100 OR OI ≥ 1000) excludes thin markets that could be manipulated into the feed
• Near-resolved markets (implied probability outside 3–97%) excluded — keeps forward-looking signal only
• Input-not-output frame: raw prices, probabilities, volumes, and open interest are computed internally for ranking but never exposed in the public payload. The linkout is the user's path to live data on Kalshi's own surface.

Authentication

OAuth 2.1 + PKCE. Public clients (Claude/ChatGPT/Cursor's MCP connectors) auto-register via Dynamic Client Registration (RFC 7591) at /oauth/register. No manual API key needed.

x402 micropayments

The premium tool (get_vertical_briefing) is metered via x402 over USDC on Base mainnet. Agents pay per call, no upfront contract. All 20 other tools require no payment — the Declassified, discovery, and partner tools need no auth at all, and the listener/article tools require only OAuth.

70/20/10 revenue split: 70% to the publisher, 20% to the recommending agent, 10% to Storyflo. On-chain and deterministic.
