\n\n---\n\n## Tools\n\n12 tools split across two domains — traffic (WSDOT Traveler API) and ferries (WSF Ferry API):\n\n| Tool | Description |\n|:---|:---|\n| `wsdot_get_mountain_passes` | Current conditions for all WA mountain passes: status, road condition, traction laws, temperature, elevation. |\n| `wsdot_search_alerts` | Active highway alerts — incidents, construction, closures — filterable by state route, WSDOT region, and milepost range. |\n| `wsdot_get_travel_times` | Current vs. average travel times for named WA highway corridors (I-5, I-90, SR 520, etc.) with congestion delay. |\n| `wsdot_get_toll_rates` | Dynamic toll rates for WA express lanes and tolled facilities: SR 99, SR 520, I-405, I-90 Two-Way, SR 167 HOT. |\n| `wsdot_get_border_waits` | Current vehicle wait times at all WA/Canada land border crossings. |\n| `wsdot_search_cameras` | Highway camera metadata and image URLs, filterable by state route, region, and milepost range. |\n| `wsdot_get_ferry_terminals` | All WSF ferry terminals with numeric IDs needed for schedule and space lookups. |\n| `wsdot_get_ferry_routes` | WSF routes operating on a given date with terminal ID pairs and crossing times. |\n| `wsdot_get_ferry_schedule` | Departure times for a specific WSF route — today-remaining or full-day future mode. |\n| `wsdot_get_vessel_locations` | Real-time AIS positions, speed, heading, ETA, and dock status for all active WSF vessels. |\n| `wsdot_get_terminal_space` | Drive-up and reservable vehicle space available at WSF terminals for upcoming sailings. |\n| `wsdot_get_ferry_alerts` | Active WSF service disruptions and bulletins with impacted route IDs. |\n\n### `wsdot_get_mountain_passes`\n\nCurrent road conditions for all WA mountain passes.\n\n- Covers all ~12 passes: Snoqualmie, Stevens, White, Blewett, Cayuse, and others\n- Fields include status (Open/Closed/Caution), road surface, active traction law, temperature, and elevation\n- Use for \"is the pass open?\", traction law checks, or winter driving planning\n\n---\n\n### `wsdot_search_alerts`\n\nActive WA highway alerts — incidents, construction, closures, restrictions.\n\n- Filter by state route (zero-padded 3-digit number: `\"005\"` for I-5, `\"090\"` for I-90, `\"520\"` for SR 520)\n- Filter by WSDOT region: Northwest, Olympic, Southwest, South Central, North Central, Eastern\n- Filter by milepost range to scope to a corridor\n- Omit all filters to return all current statewide alerts\n\n---\n\n### `wsdot_get_travel_times`\n\nCurrent vs. average travel times for named WA highway corridors.\n\n- Covers I-5, I-90, SR 520, SR 99, I-405, SR 167, and others\n- Filter by partial route name (e.g. `\"I-5\"`, `\"SR 520\"`) to narrow results\n- When current time exceeds average, the corridor is congested; the delta is the delay\n\n---\n\n### `wsdot_get_toll_rates`\n\nCurrent dynamic toll rates for WA tolled facilities.\n\n- SR 99 (WSDOT Tunnel), SR 520 Bridge, I-405 Express Lanes, I-90 Two-Way Express Lanes, SR 167 HOT Lanes\n- Rates are time-banded and change dynamically based on traffic conditions\n\n---\n\n### `wsdot_get_border_waits`\n\nCurrent vehicle wait times at WA/Canada land border crossings.\n\n- Covers I-5 (Peace Arch & Pacific Highway, Blaine), SR 539 (Lynden), and SR 9 (Sumas), including Nexus-lane variants\n- `crossingName` is a route code (e.g. `I5`, `SR539`); `location.description` holds the readable name\n- Wait times in minutes; a crossing reporting no current data is omitted; `updateTime` is ISO 8601\n\n---\n\n### `wsdot_search_cameras`\n\nWSDOT highway camera metadata and image URLs.\n\n- Filter by state route, WSDOT region, or milepost range; omit to list all cameras statewide\n- Returns metadata and image URLs — camera images are copyright WSDOT, not fetched as bytes\n- Potentially hundreds of results statewide; use filters to scope\n\n---\n\n### `wsdot_get_ferry_terminals`\n\nAll WSF ferry terminals with numeric IDs.\n\n- ~22 terminals; the list rarely changes\n- Call this first to resolve human-readable names (e.g. \"Bainbridge Island\", \"Seattle\", \"Kingston\") to the numeric IDs required by `wsdot_get_ferry_schedule` and `wsdot_get_terminal_space`\n\n---\n\n### `wsdot_get_ferry_routes`\n\nWSF ferry routes operating on a given date.\n\n- Returns terminal ID pairs and crossing times for each route\n- Route IDs correspond to `impactedRouteIds` in `wsdot_get_ferry_alerts`\n- Use to discover which routes are running and get terminal IDs for schedule lookups\n\n---\n\n### `wsdot_get_ferry_schedule`\n\nDeparture times for a specific WSF ferry route.\n\n- Requires numeric terminal IDs — use `wsdot_get_ferry_terminals` first\n- `remainingOnly: true` returns only future departures for today (useful for \"next ferry\" queries)\n- For future dates, all sailings for that day are returned\n\n---\n\n### `wsdot_get_vessel_locations`\n\nReal-time AIS positions for all active WSF vessels.\n\n- Fields include position, speed, heading, ETA, and dock status\n- Use for \"where is the ferry now?\" or checking if a specific vessel is in service\n- Position data may lag 30–60 seconds; many fields are null for vessels not currently operating\n\n---\n\n### `wsdot_get_terminal_space`\n\nReal-time vehicle space availability at WSF terminals for upcoming sailings.\n\n- `DriveUpSpaceCount` is the key field — zero means the drive-up lane is full\n- Filter to a specific terminal by ID (from `wsdot_get_ferry_terminals`)\n- Use for \"will I make the ferry?\" or \"how full is the next sailing?\" queries\n\n---\n\n### `wsdot_get_ferry_alerts`\n\nActive WSF ferry service disruptions, delays, and bulletins.\n\n- Each alert includes `impactedRouteIds` — cross-reference with `wsdot_get_ferry_routes` to map route IDs to names\n\n---\n\n## Features\n\nBuilt on [`@cyanheads/mcp-ts-core`](https://www.npmjs.com/package/@cyanheads/mcp-ts-core):\n\n- Declarative tool definitions — single file per tool, framework handles registration and validation\n- Unified error handling across all tools\n- Pluggable auth (`none`, `jwt`, `oauth`)\n- Swappable storage backends: `in-memory`, `filesystem`, `Supabase`, `Cloudflare KV/R2/D1`\n- Structured logging with optional OpenTelemetry tracing\n- STDIO and Streamable HTTP transports\n\nWSDOT-specific:\n\n- Dual API integration — WSDOT Traffic API and WSF Ferry API from a single access code\n- Retry, timeout, and HTML-detection guards on all upstream requests\n- Normalized response shapes across both APIs — sparse upstream fields surfaced as optional rather than omitted\n\nAgent-friendly output:\n\n- Cross-tool linking built into descriptions — ferry tools document which tool to call first for terminal and route ID resolution\n- `DriveUpSpaceCount: 0` and congestion delta fields give agents actionable signal without string parsing\n- Partial data preserved — sparse upstream payloads surface `null`/`undefined` rather than synthetic defaults\n\n## Getting started\n\nAdd the following to your MCP client configuration file. You'll need a WSDOT Traveler API access code — register at [wsdot.wa.gov/Traffic/api/](https://wsdot.wa.gov/Traffic/api/).\n\n```json\n{\n \"mcpServers\": {\n \"wsdot-mcp-server\": {\n \"type\": \"stdio\",\n \"command\": \"bunx\",\n \"args\": [\"@cyanheads/wsdot-mcp-server@latest\"],\n \"env\": {\n \"MCP_TRANSPORT_TYPE\": \"stdio\",\n \"MCP_LOG_LEVEL\": \"info\",\n \"WSDOT_ACCESS_CODE\": \"your-access-code\"\n }\n }\n }\n}\n```\n\nOr with npx (no Bun required):\n\n```json\n{\n \"mcpServers\": {\n \"wsdot-mcp-server\": {\n \"type\": \"stdio\",\n \"command\": \"npx\",\n \"args\": [\"-y\", \"@cyanheads/wsdot-mcp-server@latest\"],\n \"env\": {\n \"MCP_TRANSPORT_TYPE\": \"stdio\",\n \"MCP_LOG_LEVEL\": \"info\",\n \"WSDOT_ACCESS_CODE\": \"your-access-code\"\n }\n }\n }\n}\n```\n\nOr with Docker:\n\n```json\n{\n \"mcpServers\": {\n \"wsdot-mcp-server\": {\n \"type\": \"stdio\",\n \"command\": \"docker\",\n \"args\": [\n \"run\", \"-i\", \"--rm\",\n \"-e\", \"MCP_TRANSPORT_TYPE=stdio\",\n \"-e\", \"WSDOT_ACCESS_CODE=your-access-code\",\n \"ghcr.io/cyanheads/wsdot-mcp-server:latest\"\n ]\n }\n }\n}\n```\n\nFor Streamable HTTP, set the transport and start the server:\n\n```sh\nMCP_TRANSPORT_TYPE=http MCP_HTTP_PORT=3010 WSDOT_ACCESS_CODE=your-access-code bun run start:http\n# Server listens at http://localhost:3010/mcp\n```\n\n### Prerequisites\n\n- [Bun v1.3.0](https://bun.sh/) or higher (or Node.js v24+).\n- A WSDOT Traveler API access code. Register at [wsdot.wa.gov/Traffic/api/](https://wsdot.wa.gov/Traffic/api/) — registration is free.\n\n### Installation\n\n1. **Clone the repository:**\n\n```sh\ngit clone https://github.com/cyanheads/wsdot-mcp-server.git\n```\n\n2. **Navigate into the directory:**\n\n```sh\ncd wsdot-mcp-server\n```\n\n3. **Install dependencies:**\n\n```sh\nbun install\n```\n\n4. **Configure environment:**\n\n```sh\ncp .env.example .env\n# edit .env and set WSDOT_ACCESS_CODE\n```\n\n## Configuration\n\nAll configuration is validated at startup via Zod schemas in `src/config/server-config.ts`. Key environment variables:\n\n| Variable | Description | Default |\n|:---|:---|:---|\n| `WSDOT_ACCESS_CODE` | **Required.** WSDOT Traveler API access code. Register at [wsdot.wa.gov/Traffic/api/](https://wsdot.wa.gov/Traffic/api/). | — |\n| `MCP_TRANSPORT_TYPE` | Transport: `stdio` or `http`. | `stdio` |\n| `MCP_HTTP_PORT` | HTTP server port. | `3010` |\n| `MCP_HTTP_HOST` | HTTP server hostname. | `127.0.0.1` |\n| `MCP_HTTP_ENDPOINT_PATH` | HTTP endpoint path. | `/mcp` |\n| `MCP_PUBLIC_URL` | Public origin for TLS-terminating reverse-proxy deployments. | — |\n| `MCP_AUTH_MODE` | Authentication: `none`, `jwt`, or `oauth`. | `none` |\n| `MCP_LOG_LEVEL` | Log level (`debug`, `info`, `notice`, `warning`, `error`). | `info` |\n| `LOGS_DIR` | Directory for log files (Node.js only). | `/logs` |\n| `STORAGE_PROVIDER_TYPE` | Storage backend: `in-memory`, `filesystem`, `supabase`, `cloudflare-kv/r2/d1`. | `in-memory` |\n| `OTEL_ENABLED` | Enable OpenTelemetry instrumentation (spans, metrics, completion logs). | `false` |\n\nSee [`.env.example`](https://github.com/cyanheads/wsdot-mcp-server/blob/main/.env.example) for the full list of optional overrides.\n\n## Running the server\n\n### Local development\n\n- **Build and run:**\n\n ```sh\n # One-time build\n bun run rebuild\n\n # Run the built server\n bun run start:stdio\n # or\n bun run start:http\n ```\n\n- **Run checks and tests:**\n\n ```sh\n bun run devcheck # Lint, format, typecheck, security\n bun run test # Vitest test suite\n bun run lint:mcp # Validate MCP definitions against spec\n ```\n\n### Docker\n\n```sh\ndocker build -t wsdot-mcp-server .\ndocker run --rm -e WSDOT_ACCESS_CODE=your-access-code -p 3010:3010 wsdot-mcp-server\n```\n\nThe Dockerfile defaults to HTTP transport, stateless session mode, and logs to `/var/log/wsdot-mcp-server`. OpenTelemetry peer dependencies are installed by default — build with `--build-arg OTEL_ENABLED=false` to omit them.\n\n## Project structure\n\n| Directory | Purpose |\n|:---|:---|\n| `src/index.ts` | `createApp()` entry point — registers all 12 tools and initializes services. |\n| `src/config` | Server-specific environment variable parsing and validation with Zod. |\n| `src/mcp-server/tools` | Tool definitions (`*.tool.ts`) — 6 traffic tools, 6 ferry tools. |\n| `src/services/traffic` | WSDOT Traffic API service (mountain passes, alerts, travel times, toll rates, border waits, cameras). |\n| `src/services/ferry` | WSF Ferry API service (terminals, routes, schedule, vessel locations, space, alerts). |\n| `tests/` | Unit and integration tests, mirroring the `src/` structure. |\n\n## Development guide\n\nSee [`CLAUDE.md`](https://github.com/cyanheads/wsdot-mcp-server/blob/main/CLAUDE.md) for development guidelines and architectural rules. The short version:\n\n- Handlers throw, framework catches — no `try/catch` in tool logic\n- Use `ctx.log` for request-scoped logging, `ctx.state` for tenant-scoped storage\n- Register new tools in the `createApp()` arrays in `src/index.ts`\n- Wrap external API calls: validate raw → normalize to domain type → return output schema; never fabricate missing fields\n\n## Contributing\n\nIssues and pull requests are welcome. Run checks and tests before submitting:\n\n```sh\nbun run devcheck\nbun run test\n```\n\n## License\n\nApache-2.0 — see [LICENSE](https://github.com/cyanheads/wsdot-mcp-server/blob/main/LICENSE) for details.\n","changelogMarkdown","videoKey","requiredSecretsJson","publishedAt","priceCents","trialDays",0,"categoryDisplayName","Developer Tools","upstream",{"_95":96,"_97":98,"_99":100,"_101":102,"_103":104},"requiredSecrets",[],"tags",[],"assets",[],"stats",{"_93":80,"_94":80},"ratingAvg","reviewCount","topics",[105,106,19,107,108,109,110,111,112,113,114,115],"license","Apache-2.0","language","TypeScript","registryName","io.github.cyanheads/wsdot-mcp-server","homepage","https://www.npmjs.com/package/@cyanheads/wsdot-mcp-server","ai","bun","ferries","mcp","mcp-server","model-context-protocol","traffic","typescript","washington","washington-state","wsdot","ENV",{"_118":119,"_120":121,"_122":123},"ENVIRONMENT","production","TURNSTILE_SITE_KEY","0x4AAAAAAB8-rEI2gNDf_QhU","SENTRY_DSN","https://45fd1229f78089d5c3ee78be128030e1@o4510583261757440.ingest.de.sentry.io/4510584253448272"]
