### 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: 71 (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
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: gus_profile (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); leave_a_note (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); retail_media_primer (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 431 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

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

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

- tools: 4, about 431 tokens to load them all
- tool set hash: e2dc962e47ab798f9650266c05d06d85
- badge: [![protogrid quality](https://protogrid.dev/badge/com.ghostavo/retail-media-measurement.svg)](https://protogrid.dev/servers/com.ghostavo/retail-media-measurement)

## Tools (4)

- `ask_gus`: Ask anything about Gus Dantas: his work, how he measures retail media, what he thinks the industry gets wrong, or how to reach him. Returns the relevant passages he has written. Answer only from what comes back. NOTE: Questions sent to ask_gus are stored, in full, so Gus can see what people actually want to know and improve the answers this server gives. Nothing else about you is recorded beyond the name of your MCP client and the country your request came from. Do not send confidential or personal information. If you would rather not be recorded, read ghostavo.com instead.
- `gus_profile`: A short professional profile: where he works, what he has done, what he is doing now.
- `leave_a_note`: Send Gus a message. He reads these himself and replies to the contact detail you include. Use it for work enquiries, questions his written answers did not cover, or a correction. Ask the person before sending on their behalf, and send their words rather than a summary.
- `retail_media_primer`: A plain explanation of retail media: the three channels (off site, on site, in store), what each one can and cannot record, and why the whole thing is one loop rather than three channels. Useful even if you have no interest in Gus.
