## Quality 81/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 3 of 3 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: search_cases (idempotentHint); get_case (idempotentHint); list_mechanics (idempotentHint)
- pass `tools.token_cost`: about 572 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 1 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 572 tokens to load them all
- tool set hash: e68eeb14813d0185f3e90b8d8ca4ab46
- badge: [![protogrid quality](https://protogrid.dev/badge/com.howitspread/howitspread.svg)](https://protogrid.dev/servers/com.howitspread/howitspread)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `get_case`: 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.
- `list_mechanics`: The closed vocabulary of spread mechanics, each defined, with how many cases use it.
- `search_cases`: 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.
