Tools

Nine tools across two GDELT APIs — DOC API for global print/web news (last 3 months, 65 languages, no auth) and TV API for US television transcripts (2009–Oct 2024, 150+ stations):

gdelt_search_articles

Search the last 3 months of global news with GDELT's full query syntax.

• Keywords, phrases ("bird flu"), boolean OR, and exclusion (-sports)
• Filter operators: sourcecountry:, sourcelang:, domain:, theme: (GKG taxonomy), tone</tone>
• Proximity and repetition: near20:"flu virus", repeat3:"outbreak"
• Configurable sort (relevance, dateDesc, dateAsc, toneDesc, toneAsc, hybridRel) and result count (up to 250)
• Returns URL, title, publication date, domain, language, source country, and social image URL
• 250 is a hard per-call ceiling, not a page size — GDELT exposes no cursor. Fill it and the response returns continuationWindows: the queried window halved, ready to re-query. The halves overlap by a second so nothing falls through the seam; de-duplicate by url
• Query is echoed in response for chaining

gdelt_get_coverage_timeline

Retrieve when coverage of a topic spiked, with three modes:

• volume — normalized percentage of all global coverage per timestep
• volume_with_articles — volume plus top articles driving each spike; use for signal detection without a follow-up search call
• tone — average sentiment score per timestep (combine with gdelt_get_tone_distribution for the full picture)
• Every article reference is always in structuredContent; the text surface renders the first 3 links per timestep beside that timestep's true count, and points: ["<date>"] renders named timesteps in full
• Configurable smoothing and time range

gdelt_get_tone_distribution

Snapshot tone histogram across all articles matching a query.

• Bins from approximately −30 to +30; each bin includes representative article URLs
• Summary fields: peakNegativeBin, peakPositiveBin, neutralPct (% of articles in the −2 to +2 range)
• Distinct from the tone timeline — distribution across all matching articles, not over time

gdelt_get_coverage_breakdown

Multi-series time series showing which countries or languages drove coverage.

• Break down by language or country
• Top 10 series by total volume; remaining series aggregated into an "Other" bucket and named in otherSeriesLabels
• Nothing is dissolved into "Other" anonymously — pass any label to series: ["<label>"] and that series comes back complete under selectedSeries, alongside the usual overview
• Values are normalized — the topic's share of media output, not absolute article counts. Small media markets with concentrated coverage rank above large markets with diverse output, so a high value means the topic dominated that source's coverage rather than that it published the most articles
• Use to trace how a story propagated geographically

gdelt_search_tv

Search US television news transcripts (2009–Oct 2024) with per-station airtime analysis.

• Up to 10 structured stations (e.g. ["CNN", "FOXNEWS"]) — or place a station: selector directly in the query
• Normalize query-matching coverage to relative airtime % or return raw matching 15-second clip counts
• Optional dateres aggregation: hour, day, week, month, or year; returned timestamps are normalized to ISO 8601
• Responses select at most 500 points per page in deterministic date-then-station order, then group them by station. Use nextOffset with the same query inputs to retrieve the next page; content[] renders every point in the structured page
• TV-specific operators: market:, show:, context:
• Use gdelt_list_tv_stations to verify station active date ranges before querying recent events

gdelt_get_tv_clips

Retrieve actual TV news clips driving a coverage signal.

• Up to 3,000 clips per call
• Each clip: show name, station, air timestamp, 15-second transcript excerpt, direct Archive.org link, and optional thumbnail
• 3,000 is a hard per-call ceiling, not a page size — GDELT exposes no cursor. Fill it and the response returns continuationWindows: the queried window halved, ready to re-query. The halves overlap by a second so nothing falls through the seam; de-duplicate by archiveUrl
• Sort by relevance, date descending, or date ascending

gdelt_get_tv_context

Vocabulary framing analysis for TV coverage of a topic.

• Returns the most frequent non-stopword terms from matching clips
• Relative frequency scores (query term = 100)
• Use to identify narrative framing, related concepts, or follow-up search terms

gdelt_get_tv_trending

Zero-argument entry point for the current TV news cycle.

• Returns trending topics, keywords, and phrases dominating national networks
• Updated every 15 minutes
• Note: coverage data ends Oct 2024; results reflect the archive endpoint, not a live feed

gdelt_list_tv_stations

Station metadata lookup before querying.

• All available stations with market, network, monitoring start date, and end date
• isActive flag — true when end date is within the last 24 hours
• Use to verify a station was active during a target time period

Features

Built on @cyanheads/mcp-ts-core:

• Declarative tool definitions — single file per tool, framework handles registration and validation
• Unified error handling — handlers throw, framework catches, classifies, and formats
• Pluggable auth: none, jwt, oauth
• Swappable storage backends: in-memory, filesystem, Supabase, Cloudflare KV/R2/D1
• Structured logging with optional OpenTelemetry tracing
• STDIO and Streamable HTTP transports
