Infobroker

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 zero-config providers ship in the box — search the web, look up facts, fetch articles — with nothing to configure. Six more providers unlock with an API key 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

npx -y infobroker

The npm package ships its default configuration. The server resolves it from the installed package, so no environment variable is required. Your own overrides live at ~/.config/infobroker/config.local.json, or at a path set by INFOBROKER_CONFIG_LOCAL.

To run from a clone instead:

cd Infobroker && npm install && npm run start

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

{

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

For an npm install, point instructions and skills.paths at node_modules/infobroker/... and use ["npx", "-y", "infobroker"] as the command. On Windows, quote paths containing backslashes.

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

Most free providers work immediately; CORE needs a free API key. The keyed providers — Brave, Exa, Tavily, Yep — unlock higher throughput and specialized search, and self-hosted SearXNG gives full query privacy:

export INFOBROKER_BRAVE_API_KEY="your-key"

export INFOBROKER_EXA_API_KEY="your-key"

Requirements: Node.js 24+.

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. Common operators (site:, filetype:, quoted phrases) pass through to engines that support them, a preferred language is honored where a provider allows it, and anything the serving provider drops is reported rather than hidden. Pass an array of queries to batch several searches in one call. Ask for a deep read and it fetches the top results, then ranks each page's passages against your query, so you get the specific text that answers the question instead of links. Pass analyze: true and the same response carries topic terms, entity mentions, semantic clusters, and a dated timeline derived from those results — computed in-process, with no extra request. 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?"

fetch_page hands any URL to Jina Reader, which renders it as clean Markdown optimized for LLM consumption. It falls back to native HTTP when Jina is throttled. Wikipedia and Internet Archive have dedicated renderers for source-specific extraction. Ask a page a question — pass question to fetch_page and it returns the passages that answer it, each scored and ranked, instead of the whole document. Built-in web fetchers return raw HTML; Infobroker gives you clean, readable content from any source — ready for summarization or analysis. Fetch also reports the page's last-updated date when it can determine one, so you know how current your source is.

Citations

"Give me BibTeX references for papers on hyperdrive field dynamics."

"Cite the paper that first described the hyperdrive field equations."

get_citations searches scholarly sources and returns each reference as a formatted BibTeX e
