Brave Search MCP Server: web results, images, videos, rich results, AI summaries, and more.
Nothing to run from here
Knowngood is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Search agent-ready sites or fetch one site's report; every capability probe-verified, dated.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http knowngood-mcp https://knowngood.sh/mcp
# 2 — ask your agent for something these tools do
# check_webmcp, find_capability, get_site_report
Knowngood costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http knowngood-mcp https://knowngood.sh/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
3 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Check a website LIVE for WebMCP tools, and where a browser is available whether any tool actually registers when the page runs. Returns one of: registered, declared_only, declared, not_declared, could_not_ask, or excluded when the site's robots.txt refuses AI input. could_not_ask is a distinct answer and is never reported as a no. Tools are listed, never called. Reads only the site named plus publ
| Parameter | Type | Required | Notes |
|---|---|---|---|
| url | string | yes | The site to check. A hostname or a full URL; https is assumed. |
Find websites where an agent can accomplish a task. Returns probe-verified agent-readiness signals, unverified apparent actions read from page content, the verification tier, how each site was found (it declared agent access, probe discovery, or it was submitted), and a report URL to cite. Returns count:0 with an empty_note when nothing in the index matches — never a nearest guess.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| query | string | no | What you are trying to do, in plain language. Optional when at least one filter is set: with no query the tool lists every listed site matching the filters, in a fixed published order, with total. |
| country | string | no | ISO 3166-1 alpha-2, e.g. GB |
| entity_type | string | no | — |
| transactional | boolean | no | Only sites where an agent can act, not just read |
| has_mcp | boolean | no | Only sites whose MCP server answered tools/list when we tested; results include the tool names |
| has_md | boolean | no | Only sites with verified markdown: negotiation that passed the strict re-grade (the body is markdown and differs from the HTML), or a .md twin. Omit both class flags for the whole index — the default. |
| has_endpoint | boolean | no | Only sites with a verified endpoint surface (working MCP server or API catalog). |
| has_webmcp | boolean | no | Only sites whose in-page WebMCP tools were RUNTIME-VERIFIED: the page was executed in a headless browser with a modelContext supplied, and it registered at least one tool. Source-only hosts — the regi |
| limit | integer | no | — |
Fetch Known Good's dated verification report for one listed website: which capabilities were tested, which passed, when it was probed, what an agent can apparently do there, and how the site was found: whether it declared agent access, came from probe discovery, or was submitted. Answers "is this specific host agent-ready?". Returns found:false for anything not in the index — it never guesses a ne

—Grade not published
No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.9.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Knowngood can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
