WorldMonitor exposes 39 live tools — markets, conflict events, maritime chokepoints, aviation, climate, AI briefs — over the Model Context Protocol. This page is the shortest path from zero to a useful response inside Claude. Everything else in the MCP Server reference is optional reading once this works.Documentation Index

1. Pick a tier and grab credentials
Free accounts can’t reach the MCP server — the OAuth flow returns401 INSUFFICIENT_TIER. You need one of:
- Pro — sign in with your WorldMonitor account, no key to manage. 50 tool calls per UTC day.
- API Starter / Business / Enterprise — paste a
wm_live_…key in your client, or use the same OAuth flow as Pro. 1,000 / 10,000 / unlimited calls per day.
wm_… key into a curl script, jump to Server-side curl at the bottom.
2. Add the server to Claude Desktop
Edit~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the Windows equivalent at %APPDATA%\Claude\claude_desktop_config.json and add the worldmonitor entry:
3. Ask your first question
Open a new chat in Claude Desktop and try:What’s the current US equity market sentiment and which sectors are leading or lagging today?Claude will pick
get_market_data from the WorldMonitor toolset, call it with no arguments, and answer in plain English. The raw tool response is a single bootstrap bundle covering quotes, sector ETFs, crypto, gulf quotes, ETF flows, and the WorldMonitor fear-greed composite. Typical latency: 300–800 ms (cache read from Redis, no upstream API call).
Behind the scenes, the tool call looks like this:
text field is the JSON payload:
cached_at— ISO timestamp of the oldest contributing data point. Use this to reason about how fresh the answer is.stale—truewhen any contributing seed exceeded its freshness budget. Tells the model when to caveat its answer.
4. Trim the response (when it matters)
get_market_data returns roughly 100 KB unfiltered. That’s fine for one call, but if you’re chaining several reads inside a longer conversation, you’ll burn context fast. Every tool accepts an optional jmespath argument that projects the response server-side before it crosses the wire:
5. Browse the full tool catalog
get_market_data is one of 39 tools. The rest cover:
- Geopolitical & security —
get_conflict_events,get_country_risk,get_military_posture,get_cyber_threats,get_sanctions_data,get_news_intelligence. - Movement & infrastructure —
get_chokepoint_status,get_maritime_activity,get_airspace,get_aviation_status,search_flights. - Energy & macro —
get_energy_intelligence,get_economic_data,get_country_macro,get_tariff_trends,get_eu_housing_cycle,get_eu_quarterly_gov_debt,get_eu_industrial_production. - Environment & health —
get_climate_data,get_natural_disasters,get_radiation_data,get_health_signals. - AI synthesis (live LLM, slower — 1–4 s) —
get_world_brief,get_country_brief,analyze_situation,generate_forecasts.
curl examples are in the MCP Tools Reference. When the compressed tools/list description is ambiguous about a specific tool, call describe_tool with tool_name: "<name>" for the full uncompressed definition — it’s exempt from your daily quota, so use it freely while exploring.
What just happened
The MCP handshake is invisible from the chat side, but here’s the sequence so you know where to look if something breaks:- Claude Desktop reads
claude_desktop_config.json, sees the WorldMonitor server, and on first use POSTsinitializetohttps://worldmonitor.app/mcp. The server responds with its capabilities, the protocol version (2025-03-26), and a session-levelinstructionsstring that tells the model about the universaljmespathargument. - Claude Desktop calls
tools/listand receives 39 compressed tool descriptions (≤120bytes per tool). The compressed form keepstools/listcheap;describe_toolreturns the full definition on demand. - When you ask a question that needs live data, Claude picks a tool, calls
tools/call, and inlines the response into its reply. Cache tools return in under a second; LLM-backed tools (get_world_brief,analyze_situation, etc.) take 1–4 s.
Server-side curl
If you’d rather skip the OAuth dance and drive MCP from a script:wm_live_… key goes in X-WorldMonitor-Key, not as a Bearer token — sending it as a bearer fails OAuth resolution and returns 401 invalid_token. If you already have an OAuth access token from /api/oauth/token, use Authorization: Bearer $TOKEN instead and drop the X-WorldMonitor-Key header.
Where to go next
- JMESPath guide — projection grammar with 12 worked examples against real response shapes. Read this before your second day of MCP use; it will pay for itself in saved tokens within an hour.
- MCP Tools Reference — per-tool parameters, freshness budgets, API endpoint mapping, and
curlexamples for every tool. - MCP Server reference — auth modes, OAuth setup, plans & quotas, error codes, and freshness model.
- Authentication overview — when to use a
wm_live_…key vs. OAuth vs. browser session.
Operational note (for ops, not callers)
Everyinitialize and tools/call emits a structured telemetry line tagged mcp.toolcall or mcp.initialize with latency, payload bytes (pre and post JMESPath), jmespath_used, and budget_exceeded. Pipe Vercel / log-drain consumers at this line if you want a real P95 per tool. Caller-facing behaviour is unaffected.
