ContextWire

Search for AI agents that you can run yourself

A small MCP server in front of SearXNG, with social search and public knowledge bases. It talks to search engines through their APIs only, and returns evidence with sources for your agent to reason over.

Fact cards

When a search names one person, place, organisation, work, product or idea, a fact card sits above the results: what it is, four to eight key facts chosen for its kind, and where each fact comes from. Ask for one fact ("how tall is …") and that fact comes first. Cards are built by rules from Wikidata, the Wikipedia infobox and summary, and an official site's structured data, in under three seconds and without a model. Where Wikidata and Wikipedia disagree, the card shows both. Agents get the same card as a short block of text above the results.

Social search by Wildroot

Wildroot is the strongest engine here: a live index of public Bluesky and fediverse posts from the last two days, searched by keywords and by meaning, with each network's opt-outs respected. ContextWire's social tool gives an agent every Wildroot control: network, time window, topic, intent (news and information, questions, recommendations and more), funny and live filters, exact phrases, hashtags, accounts, linked sites, exclusions, and "posts like this one". The news profile draws on it too.

Try it yourself at wildroot.io/search, or browse the feeds at wildroot.io.

Connect your agent

The demo speaks MCP over HTTP at https://contextwire.dev/mcp.

{
  "mcpServers": {
    "contextwire": { "type": "http", "url": "https://contextwire.dev/mcp" }
  }
}

Claude Code: claude mcp add --transport http contextwire https://contextwire.dev/mcp

The same tools are plain HTTP too, for example /api/search?q=heat+pump&profile=social.

Tools

Tool	What it does
search	Search with a profile that picks the right engines. Results are merged, deduplicated and reranked, and say which engines found them.
social	Live Bluesky and fediverse posts through Wildroot, with topic, intent and time filters. Works without a key.
read	Fetch a page as clean markdown, or only the passages that bear on a question.
fact	Structured facts from Wikidata with the Wikipedia summary.
card	A fact card about one thing: key facts with their sources, the asked fact first. Works without a key.
papers	Scholarly papers with authors, venue, citations, abstract and DOI.
evidence	Cited passages for a question from several sources in one call (needs a key here).

Demo limits

This is a small public demo, so it is limited.

• Social results are public Bluesky and fediverse posts from the last two days, through Wildroot, which applies each network's opt-out rules.
• No search site is scraped. Without a key, the web profile covers Wikipedia full-text search, its sister sites and the Mwmbl open index. Full web results come from a paid search API and are for key holders.
• The log records which tool ran and how it ended. It does not record your query or your address.

Run your own

ContextWire is built to run next to your own SearXNG as a private MCP server, with no limits and your own choice of engines, rerankers and sources. The code is being prepared for release at github.com/keptlive/contextwire-mcp.
