dipper
Registry code: efe0804e489276f5
Dipper gives you live web search (web_search) and web page reading (web_fetch). Use web_search for current events, facts you are unsure of, or anything after your training data; use web_fetch to read a specific URL in full. Search queries are limited to 128 characters, so write short keyword queries rather than full questions. This is the free Dipper endpoint: everyone shares a small hourly limit (a cached result counts as 0.2 of a request) and refresh is not available, so avoid redundant calls.

- Is dipper live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is dipper free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does dipper have?
- 2 tools: web_search, web_fetch.
- Is dipper safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
web_search unknown 1h ago
Search the web and get a ranked list of results with title, URL, date and a short summary. Use it when you need current or external information: recent events, documentation, prices, facts you are not sure about. Prefer one well-chosen query over many similar ones; if the summaries are not enough, call web_fetch on the most relevant URL instead of searching again. Query rules: - At most 128 characters. Write concise keywords, not a long question. - Operators (combine freely): site:example.com only results from that site -site:example.com exclude that site lang:en results in a language (e.g. lang:zh, lang:en) after:2025-01-01 published on or after a date (YYYY-MM-DD) before:2025-12-31 published before a date - Example: "cloudflare durable objects pricing site:developers.cloudflare.com after:2025-06-01" max_results: number of results (1-50, default 10). Asking for more does not cost more but uses more context. include_content: include the full page text of every result. This is very large (often thousands of tokens per result) and rarely needed — leave it false and use web_fetch on one or two chosen URLs instead. Results may come from a shared cache. refresh: skip the cache and search again now; the new results also replace the cached copy for everyone. Billed at the full (uncached) rate, so only set it when the user needs the latest information or a cached result looks out of date.

Fetch a web page and return its title and main content as Markdown. Use it to read a specific page in full: a URL the user gave you, or a promising result from web_search whose snippet was not enough. Only http and https URLs are supported. Pages may be served from a shared cache; set refresh to read the live page (billed at the full rate) when the page changes often or the cached copy looks stale.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idefe0804e489276f5.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/efe0804e489276f5/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
