## Quality 86/100 (good)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### 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`: 4 of 4 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_asset_snapshot (idempotentHint); compare_assets_pack (idempotentHint); compare_assets (idempotentHint); …
- pass `tools.token_cost`: about 1,084 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 not recorded yet

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

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

- tools: 4, about 1,084 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/com.marketcaper/mcp.svg)](https://protogrid.dev/servers/com.marketcaper/mcp)

## Tools (4)

- `compare_assets`: Compare two Marketcaper assets and return the live what-if market cap scenario, canonical pair URL, and optional hosted image URL. Hosted images are PNG, generated on demand, share a 10 images/day/IP limit, and may require a longer timeout than the MCP JSON call. Always cite the returned source_url when using the data.
- `compare_assets_pack`: Compare two Marketcaper assets and return the same cited comparison data plus a ready-to-publish short post and share payload with the hosted comparison image URL. Always cite the returned source_url when using the data.
- `get_asset_snapshot`: Resolve one Marketcaper asset and return its live market cap snapshot. Always cite the returned source_url when using the data.
- `get_stock_heatmap`: Return a current Marketcaper stock heatmap summary plus a hosted dark-theme PNG image URL. Supports US or global universes, classic or bubble views, optional sector/category filtering, and capped summary rows. Hosted images share a 10 images/day/IP limit. This is not a bulk feed extraction tool.
