Infobroker

One server. Every source. Research that delivers.

Infobroker is a multi-provider MCP server that unifies web search, structured knowledge, academic, archive, and content-extraction APIs behind a single tool surface. Twenty-one zero-config providers ship in the box — search the web, look up facts, fetch articles — with nothing to configure. Five more providers unlock with API keys or self-hosting. A built-in corroboration engine cross-references independent sources to separate established facts from contested claims. Bundled client skills transform raw research into polished writing. Free first. Privacy always.

North Star

Infobroker is the Bothan Spynet as a tool — a decentralized intelligence network that queries independent sources and routes results through a single, impartial interface. In intelligence-cycle terms, you supply the direction and get the dissemination; the server handles the collection and processing.

Quick Start

cd Infobroker && npm install && npm run start

Add this to your OpenCode config (~/.config/opencode/opencode.json):

{
  "instructions": [
    "<path-to-Infobroker>/instructions/search-preferences.md"
  ],
  "skills": {
    "paths": [
      "<path-to-Infobroker>/skills",
      "<path-to-opencode-config>/skills"
    ]
  },
  "mcp": {
    "infobroker": {
      "type": "local",
      "command": ["node_modules/.bin/tsx", "src/index.ts"],
      "cwd": "<path-to-Infobroker>",
      "environment": {
        "INFOBROKER_CONFIG": "<path-to-Infobroker>/config.json"
      }
    }
  }
}

The mcp block starts the server; the instructions and skills blocks are what activate the bundled client skills. Without them the skills ship in the repository but stay inert.

Free providers work immediately. API-keyed providers — Brave, Exa, Tavily, Yep — unlock higher throughput and specialized search; self-hosted SearXNG gives full query privacy:

export INFOBROKER_BRAVE_API_KEY="your-key"
export INFOBROKER_EXA_API_KEY="your-key"

Requirements: Node.js 20+.

MCP Server

Your research backend. Seven tools, twenty-six providers, one corroboration engine. The complete feature inventory is documented in the feature taxonomy in the spec.

Unified Search

"Search for the location of the second Death Star." "Find scholarly papers on hyperspace travel theories." "Search the latest astromech specs and show me the passages that answer: does the R2 unit pre-date the Clone Wars?"

search_web sends one query to every provider that can answer it. Search across DuckDuckGo, Wikipedia, academic databases, news, code repositories — or describe your task and the server picks the best source. Pass an array of queries to batch several searches in one call. Ask for a deep read and it fetches the top results and ranks each page's passages against your query, so you get the specific text that answers the question instead of links. Failed providers fall back silently through a configurable chain so you get results, not error messages. Other search tools lock you to one engine; Infobroker routes every query to the right provider and keeps going when one fails.

Content Extraction

"Fetch the article on the Battle of Yavin and summarize it." "Get the text of that page about the Death Star plans." "Where, in that report, does it mention the reactor core?"
