Grounder MCP
Live web grounding for local and cloud LLMs, as four MCP tools. Every model is frozen at its
training cutoff; Grounder gives yours the current web - ranked results, real page content, and a
cited evidence pack sized to your context window.
This is a thin stdio client for the hosted service at grounder.dev - no
browser, no scraper, nothing heavy runs locally. Get a key (free, no card) at grounder.dev.

| Tool | What it does |
|---|
web_search | Google organic results plus the surfaces around them - people-also-ask, related searches, knowledge graph. The top snippet often already holds the answer, so the model can skip a fetch. |
fetch | One page as clean markdown, capped to your token budget, plus the final URL after redirects. |
deep_search | One search, read across the pages it surfaces, chunked and ranked into a token-capped, cited evidence pack. Optional grounded answer, written only from what it read. |
research | Investigates an open question with no ready-made answer - the kind you'd hand an analyst: it plans, reads primary sources, notices what is still missing, goes back for it, and answers only from the pages it actually read. |
Why use it
- It fits a small context window. Results come back token-capped, so they slot into an 8-32k
local model instead of overflowing it. A few raw web pages can be 20,000+ tokens - we measured
22,759 for one query - which is enough to make a small model return nothing at all.
deep_search
and research hand back the relevant passages, not whole pages.
- The live page, not a cached copy.
fetch reads the actual current page on request. Any caching
is short, timestamped, and force-refreshable - it never turns into an opaque stale index.
- Flat monthly price, billed in pages. One page is one search, one fetch, or one page a
deep_search reads, and you only pay for pages actually delivered - an empty search or an
unreadable page is free. No per-call metering.
- No query content stored. Ever.
- Nothing heavy to run. The client just forwards tool calls to the hosted API, so it installs in
seconds with no browser or scraping stack on your machine.
