## Trust

- hygiene: 80
- liveness: 99
- freshness: 45
- provenance: 55
- drivers: +dns-namespace +website +reachable +uptime-97% -stale-233d -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 81/100 (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: 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: get_entity (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_entities (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); check_name_availability (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 796 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: 100 (weight 15)

- pass `deps.known_vulns`: no known advisory in 85 resolved packages
- n/a `deps.mcp_sdk_version`: the official MCP SDK is not in the dependency graph
- pass `deps.resolvable`: @sgpdirectory/mcp@1.3.2 resolved: 85 packages

- tools: 4, about 796 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/com.sgpdirectory/mcp.svg)](https://protogrid.dev/servers/com.sgpdirectory/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `check_name_availability`: Check if a proposed business entity name is available for registration in Singapore.
- `get_entity`: Get detailed information about a specific entity by UEN. If you only have a company name, call search_entities first to obtain the UEN, then call this tool.
- `search_entities`: Search, list, filter, sort, and paginate Singapore business entities. Use a query for name/UEN search, or omit query and use filters such as registrationDateStart/registrationDateEnd to list newly registered entities.
- `search_ssic`: Search for SSIC (Singapore Standard Industrial Classification) codes by keywords or find codes used by peer entities. Provide keywords (space-separated, AND logic) and/or peers (comma-separated UENs).
