wanderlog-mcp

An MCP server that lets Claude (or any MCP-compatible agent) view and build Wanderlog trip itineraries through conversation.

Instead of clicking through the Wanderlog UI to plan a trip, you just ask:

"Create a 14-day Japan Golden Route trip — Tokyo, Hakone, Kyoto, Nara, and Osaka."

The agent calls the tools, interleaves places and notes for each day, adds hotel blocks, ferries, buses, trains, rental cars, and checklists, and you end up with a fully populated Wanderlog trip in a few minutes.

See a real example: 14-day Japan Golden Route — built entirely by an AI agent using this MCP server.

What's New (Unreleased)

• Place and custom-list ordering tools support explicit 1-based positions with safe boundary validation.

• wanderlog_move_place moves an existing place between custom lists and itinerary days while preserving its complete metadata.

• Custom-list lifecycle operations now reject duplicate or ambiguous section headings instead of silently changing the first match.

• wanderlog_search_hotels — search Wanderlog's hotel aggregator across airbnb, expedia, google, and kayak. Returns ranked offers with per-vendor price comparison and faceted filter discovery so the LLM never has to memorise Wanderlog's internal enum values.

• A failed startup authentication probe now gets one shared retry on the first tool call, allowing valid sessions to recover from a transient network or proxy error without restarting the server.

• wanderlog_add_place accepts an optional place_id, so wanderlog_search_places (response_format: "detailed") now has somewhere to send its results — pass the id straight through to add the exact candidate when a name matches multiple branches or the wrong city, instead of hoping the top autocomplete match is right.

• wanderlog_annotate_place now replaces a place's existing note instead of appending the new text to it, including notes that contain images.

• Place lookups no longer fail with "Place not found" when Wanderlog's autocomplete returns an entry with no place ID ahead of the real result. This affected adding places, hotels, journal stops and transit endpoints, and wanderlog_search_places listed those entries as undefined.

What's New in v0.3.1

• Wanderlog rate-limits rapid edits — burst mutations (an LLM building a full itinerary) now retry automatically with backoff instead of failing with an opaque "Submit op timeout".

• Rate-limit rejections that can't be retried surface as a clear error instead of a 10-second hang.

• New day sections created by wanderlog_update_trip_dates now match Wanderlog's native section shape exactly.

What's New in v0.3.0

• wanderlog_search_guides + wanderlog_get_guide — discover and read user-written Wanderlog travel guides. The LLM can ask "what guides exist for Vietnam?" and pull full itineraries to use as inspiration.

• wanderlog_remove_note — remove standalone note blocks by natural-language reference.

• wanderlog_edit_note — find-and-replace across note blocks, place annotations, and checklist titles/items.

• Detailed mode no longer truncates place notes or note blocks — guides and itineraries render their full commentary.

• Fixes: notes containing embeds no longer render as [object Object]; place references now match across hyphen/dash differences (e.g. "Roppongi Hills - Tokyo City View").

What's New in v0.2.0

• wanderlog_rename_day — replace auto-generated day headings (e.g. "Barcelona") with descriptive ones ("Arrival — Feria de Abril"). Pass "" to reset back to the default.

• Tools table now documents wanderlog_annotate_place and wanderlog_add_expense (shipped previously, missing from v0.1.0 docs).

What's New in v0.1.0

• Full itinerary building: places, notes, hotels, and checklists in a single conversation

• wanderlog_search_places — find real-world places near any destination using Wanderlog's place database

• wanderlog_add_note — interleave transit tips, booking info, and local advice between places

• wanderlog_add_checklist — pre-trip and per-day checklists (visa, currency, timed-entry tickets)

• MCP server instructions injected at startup so Claude builds complete itineraries automatically

• Startup auth probe — catches expired cookies immediately instead of failing mid-conversation

Example Prompts

"What trips do I have in Wanderlog?"

"Create a 7-day itinerary for Lisbon starting June 1 — include restaurants, day trips,
and a hotel near the waterfront."

"Add a day trip to Sintra on day 3 of my Lisbon trip."

"I'm spending 5 days in Tokyo — build me a full itinerary with museum visits, ramen spots,
and a ryokan in Shinjuku."

"Look at my Barcelona trip and add practical notes for getting between each place."

"Add a pre-trip checklist to my Paris trip — visa, currency, offline maps, travel insurance."

"Move my Rome trip back by two weeks."

"Give me the shareable link to my Kyoto itinerary."

"Remove the Colosseum from day 2 of my Rome trip."

Tools

Managing custom lists

Custom sections are undated lists outside Wanderlog's protected default/system sections. Create one with wanderlog_add_section, rename it with wanderlog_update_section, and delete it with wanderlog_delete_section. Deleting is destructive: every block in that section is removed. Section headings used by these tools must be unique (matching ignores case); ambiguous or duplicate targets return errors without submitting a mutation.

Moving places between lists and days

wanderlog_move_place moves the existing place block rather than creating a copy, so its note, start/end time, images, booking fields, and unknown metadata travel with it. Supply exactly one destination: target_section for an undated custom list (or Places to visit), or target_day for day 2, May 4, or an ISO date such as 2026-05-04.

An optional position is 1-based among places at the destination; omit it to append after the last place. If a place name occurs more than once, qualify place_ref with an ordinal and/or day, for example 2nd Starbucks on day 3. Ambiguous places, duplicate section headings, unknown days, and out-of-range positions return errors without submitting a mutation.

Reordering places and custom lists

wanderlog_reorder_places changes one place's 1-based position within exactly one section or day. wanderlog_reorder_sections similarly changes one custom list's position among custom lists only. Both operations move the original object intact; they do not rebuild or truncate metadata. Position 1 selects the first place/list, and the current count selects the last.

Prerequisites

• Node.js 22 or newer

• A Wanderlog account

• An MCP-compatible client: Claude Code, Claude Desktop, OpenAI Codex, Cursor, VS Code, or any stdio MCP host

Setup

Step 1 — Get your Wanderlog session cookie

Wanderlog doesn't have a public API, so wanderlog-mcp authenticates using your browser session cookie (connect.sid). It's valid for roughly a year and never leaves your machine.

Treat it like a password — it grants the same access you have in the Wanderlog UI.

Chrome / Edge

1. Go to wanderlog.com and log in

2. Press F12 to open DevTools

3. Click the Application tab

4. In the left sidebar expand Storage → Cookies → https://wanderlog.com

5. Find the row where Name is connect.sid

6. Click the row, then double-click the Value cell and copy the full string — it starts with s%3A and is ~100 characters long

Firefox

1. Go to wanderlog.com and log in

2. Press F12 to open DevTools

3. Click the Storage tab

4. In the left sidebar expand Cookies → https://wanderlog.com

5. Find connect.sid in the table, click it, and copy the Value

Why can't I use document.cookie in the console? Wanderlog sets connect.sid with the HttpOnly flag, which deliberately blocks JavaScript from reading it (XSS protection). DevTools bypasses this restriction — that's why it works and the console doesn't.

Step 2 — Configure your MCP client

Claude Code

claude mcp add wanderlog-mcp npx wanderlog-mcp \
  --env WANDERLOG_COOKIE="s%3A...your value here..."

Claude Desktop

Edit claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

• Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "wanderlog": {
      "command": "npx",
      "args": ["wanderlog-mcp"],
      "env": {
        "WANDERLOG_COOKIE": "s%3A...your value here..."
      }
    }
  }
}

Restart Claude Desktop after saving.

Cursor

Settings → MCP → Add server, or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "wanderlog": {
      "command": "npx",
      "args": ["wanderlog-mcp"],
      "env": {
        "WANDERLOG_COOKIE": "s%3A...your value here..."
      }
    }
  }
}

VS Code (GitHub Copilot)

Add to your workspace .vscode/mcp.json:

{
  "servers": {
    "wanderlog": {
      "type": "stdio",
      "command": "npx",
      "args": ["wanderlog-mcp"],
      "env": {
        "WANDERLOG_COOKIE": "s%3A...your value here..."
      }
    }
  }
}

OpenAI Codex

Edit ~/.codex/config.toml:

[mcp_servers.wanderlog]
command = "npx"
args = ["wanderlog-mcp"]

[mcp_servers.wanderlog.env]
WANDERLOG_COOKIE = "s%3A...your value here..."

Run /mcp inside Codex to confirm the server loaded.

Smithery (one-click install)

npx @smithery/cli install wanderlog-mcp --client claude

Step 3 — Verify

Ask your agent: "What trips do I have in Wanderlog?"

It should call wanderlog_list_trips and return your account's trips. If it fails, see Troubleshooting below.

Refreshing your cookie

The cookie lasts about a year but can die sooner if you log out of wanderlog.com, change your password, or Wanderlog revokes the session. When that happens every tool call returns:

Wanderlog session invalid or expired — Capture a fresh connect.sid cookie from wanderlog.com DevTools and update WANDERLOG_COOKIE in your MCP config.

Repeat Step 1 above, update your config, and restart your MCP client.

Troubleshooting

Server starts but list_trips returns an auth error Your cookie is expired or wrong. Re-capture it from DevTools and update your config.

npx wanderlog-mcp hangs or does nothing The server speaks stdio MCP — it's designed to be launched by an MCP host, not run directly in a terminal. Run it through Claude Code or Claude Desktop as described above.

Tools work but the agent ignores notes/checklists The server injects instructions into the MCP initialize response that tell the agent to interleave places and notes and add checklists. This works reliably with Claude. Other clients may vary.

Security

• The cookie is stored only in your MCP client config, never committed or logged

• wanderlog-mcp runs entirely on your machine — there's no relay server

• The startup auth probe validates your cookie without printing its value

• To revoke access: log out of wanderlog.com (invalidates all sessions), then re-capture
