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 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 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

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
