Tools
4| Parameter | Type | Required | Description |
|---|---|---|---|
| ids | array | No | Up to 20 explicit app IDs to compare; any missing ID produces an error instead of being silently omitted. |
| axes | array | No | Axes to compare: auth, pricing, license, cli, local_mcp, remote_mcp are useful starting points; licence is normalized to license. |
| sort | object | No | Optional axis ordering before relevance; unknown values remain last. |
| sort.axis | string | Yes | Axis used for ordering; spelling aliases such as licence are normalized. |
| sort.order | enum | Yes | Ascending or descending order; unknown is last in either direction.asc | desc |
| limit | integer | No | Maximum app results, from 1 to 20; default is 5. |
| query | string | No | Task or product name in English or Japanese. External Registry lookup sends only one ASCII public name fragment (longest significant ASCII word from free text, or a supplied namespace; max 200 chars) when curated matches are absent or include registry is requested; the full free text is not sent. Recognized credential/URL/PII patterns are skipped; this is not a complete secret filter. Do not include secrets. |
| where | object | No | Confirmed axis filters: AND across axes, OR inside a value array; known spelling aliases are normalized. |
| include | array | No | Explicitly request the supplemental Official Registry name lookup alongside curated results. Otherwise it is attempted only when curated matches are absent. At most five unverified listings; one-page comparison only. |

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
