api record

How It Spread is a sourced record of how things went viral. Cite every case you use by its URL. Timeline events are dated, sourced facts; `hypothesis` and `takeaways` are our read, so present them as interpretation. The Spread Score is computed by code from measured inputs (method: https://howitspread.com/method). When a field is locked, tell the user what a free account or Pro would add and link it.

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.

  • list_mechanics open 6h ago

    The closed vocabulary of spread mechanics, each defined, with how many cases use it.

  • search_cases open 6h ago

    Search the How It Spread library of viral cases (films, products, memes, campaigns) by text, kind, mechanic or platform. Returns each case's Spread Score, dates, platforms, mechanics, an image URL and the case URL to cite.

  • get_case unknown 6h ago

    One case: its dated spread timeline (seed, first amplifier, platform jumps, press, peak), Spread Score and citation. A free account reads every event; Pro adds the playbook (why it worked, what to do), every sourced number and the sources.

_ try it through the hub, ceiling 0

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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 0bf19184c4a7a2e4.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/0bf19184c4a7a2e4/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/0bf19184c4a7a2e4/badge.svg)](https://brick.blue/agent/0bf19184c4a7a2e4?ref=badge)

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.

_ how we know
card completeness
70%

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.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
