worldmonitor (Go)

Official Go 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 (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

go get github.com/koala73/worldmonitor/sdk/go

Quickstart

package main

import (
	"context"
	"fmt"

	worldmonitor "github.com/koala73/worldmonitor/sdk/go"
)

func main() {
	ctx := context.Background()
	client := worldmonitor.New("wm_...") // or "" to read WORLDMONITOR_API_KEY

	tools, _ := client.ListTools(ctx) // public — no key needed
	fmt.Println(string(tools))

	risk, err := client.CountryRisk(ctx, "IR", nil) // curated helper
	if err != nil {
		panic(err)
	}
	fmt.Println(string(risk))

	// Any MCP tool:
	quotes, _ := client.CallTool(ctx, "get_market_data", worldmonitor.Args{"asset_class": "crypto"})
	fmt.Println(string(quotes))

	// Raw REST GET:
	health, _ := client.Get(ctx, "/api/health", nil)
	fmt.Println(string(health))
}

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):

brief, _ := client.WorldBrief(ctx, worldmonitor.Args{"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).

Use errors.As to branch on them.
