Claude Code: ask. ### `places_along_route` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Atlas inventory along a routed drive: every place of a kind within a band of the corridor between two points. This returns the raw record, not a plan — to plan a drive with stops chosen for the traveler, use plan_drive. One limit, stated: ghost-town rows live in a separate Wikidata corpus the corridor read cannot see. Asking for one here is refused rather than answered empty; reach them with search_places by state. ``` ### `places_on_byway` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Atlas places along one scenic byway: every place of a kind within a band of the drawn route, nearest to the road first, each marked whether it sits on the byway itself or is a detour off it. Only routes with drawn geometry can answer. This is the atlas inventory beside a road, not an itinerary. One limit, stated: ghost-town rows live in a separate Wikidata corpus the corridor read cannot see. Asking for one here is refused rather than answered empty; reach them with search_places by state. ``` ### `plan_drive` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Plan a scenic drive with the Byway engine: real verified stops, honest timing, official scenic byways. Origin and destination are place names — the tool resolves each to the closest matching real place. budget_min is the whole time window (driving plus stops, default 240): a long drive needs a budget comfortably above its direct drive time or there is no slack to spend on stops. Requires a connected Byway account (OAuth sign-in). Set save=true to save the trip to your account. ``` ## Only reads (7) Looks things up and changes nothing. Claude Code: allow. ### `get_byway` - The name "get_byway" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Full detail for one scenic byway or regional route: designation, states or country, length, scenic lookouts on the route, and itineraries that ride it. ``` ### `get_itinerary` - The name "get_itinerary" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text A classic road-trip itinerary: waypoints, states, and the scenic byways along the route. ``` ### `get_place` - The name "get_place" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Everything the Byway atlas holds on one place: its own description, the records it traces to (OpenStreetMap, Wikipedia, Wikidata), reconciled public records (GNIS, National Register), the scenic byways that pass near it, the nearest verified lookouts, and for a place people walk to from the car (a waterfall, peak, cliff, arch, hot spring, lighthouse or trailhead) the walk in: time, path length one way and climb, with what the numbers come from. Takes the byway.world URL search_places returned, or the place's kind and slug. ``` ### `search_byways` - The name "search_byways" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search scenic byways and signed routes — the US federal roster plus regional routes (Québec, France, Northern Ireland, Ireland, Iceland, Norway, New Zealand today; growing). Filter by name, US state, or ISO-2 country. US byways carry byway.world links. ``` ### `search_destinations` - The name "search_destinations" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find US destination cities by name or state, with the day trip around each one: the scenic byways, national parks, public land units and campgrounds Byway's registries place within 30 miles. Only cities with a proven weave are listed — every result links to its own byway.world destination page. ``` ### `search_lookouts` - The name "search_lookouts" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Scenic lookouts (viewpoints) along a specific byway, or across a US state. Every lookout is a real, verified place — coverage is growing. Where known, each carries the walk in from the car: time, path length one way and climb, or roadside (no walk). ``` ### `search_places` - The name "search_places" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search the Byway atlas of typed places — waterfalls, hot springs, lighthouses, covered bridges, historic sites, beaches, peaks, rest areas, ghost towns, museums and attractions. Locate by US state (which also needs a kind), by a point and radius, or by name; a name given alongside a locator narrows it. Every result links to the byway.world page for that place, and every place traces to its OpenStreetMap or Wikidata record. One limit, stated: ghost-town rows live in a separate Wikidata corpus that the point and name searches cannot read, so they are absent from a kind-less search. Reach them with state + kind, or with get_place. Asking for one any other way is refused, never answered empty. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `byway`: ```json { "permissions": { "allow": [ "mcp__byway__search_byways", "mcp__byway__get_byway", "mcp__byway__search_lookouts", "mcp__byway__get_itinerary", "mcp__byway__search_places", "mcp__byway__get_place", "mcp__byway__search_destinations" ], "ask": [ "mcp__byway__places_on_byway", "mcp__byway__plan_drive", "mcp__byway__places_along_route" ], "deny": [] } } ```
