worldmonitor (Ruby)
Official Ruby SDK for the World Monitor global-intelligence API — country briefs, risk scores, conflict / cyber / market / news feeds, and every MCP tool, without writing an HTTP integration.
Stdlib-only (Net::HTTP, zero dependencies), MCP-first: the same design as the official worldmonitor npm CLI. The MCP server is the live, documented agent surface; a small REST escape hatch rounds it out.
Install
gem install worldmonitor
Quickstart
require "worldmonitor"
client = WorldMonitor::Client.new(api_key: "wm_...") # or set WORLDMONITOR_API_KEY
client.list_tools # public — no key needed
client.country_risk("IR") # curated helper
client.conflict_events(country: "IR", limit: 5)
client.call_tool("get_market_data", asset_class: "crypto") # any MCP tool
client.get("/api/health") # raw REST GET
Data calls (tools/call) need a user API key — get one at worldmonitor.app/pro. Listing tools, prompts, and resources is public.
Server-side projection
Every tool accepts an optional jmespath argument that projects the response server-side (typically an 80–95% size cut):
client.world_brief(jmespath: "hotspots[].name")
See the JMESPath guide for worked examples.
Errors
WorldMonitor::MCPError— the MCP server returned a JSON-RPC error (#code, auth failures carry a key hint).WorldMonitor::APIError— a REST/transport failure (#status,#body).
Both derive from WorldMonitor::Error.
