Navan MCP Server

Navan

Navan is a corporate travel and expense platform. This bundle wraps the public Booking Data API read surface for booking, itinerary, traveler, and policy-compliance analysis. Mutation flows (creating, modifying, cancelling bookings) stay in Navan; they are not part of this bundle.

Capability areas

Booking listing

The booking listing capability returns one paginated page of bookings. Every booking is a fully-realized object with:

• Traveler — name, employee ID, email, and (where available) travel-policy group.
• Booking type — flight, hotel, car, or rail. Filter to a single type with bookingType to scope larger workspaces.
• Itinerary — origin/destination, departure and return timestamps, segment-level detail for multi-leg flights, room nights for hotels, pickup/dropoff for cars.
• Compliance — Navan's inPolicy flag plus the policy reason if the booking was flagged out-of-policy.
• Cost — currency, total amount, and (where surfaced by Navan) breakdown by tax / fees.

Pagination uses page (cursor token returned by the previous response) and size (page size, default 10, raise as far as the upstream allows when sweeping).

Workflows

Expense reconciliation: sweep bookings for the trailing 30 days, group by traveler + booking type, and cross-join with the expense system on traveler email + travel date. Surface bookings that have no matching expense report and expense reports that have no matching booking — both sides are signal.

Compliance audit: filter to bookingType of interest, page through with a large size, and group by the in-policy flag. Out-of-policy bookings are the actionable list.

Traveler care: filter to upcoming bookings and join against an HR roster to flag travelers in regions with active disruptions (weather, strike, political event). Navan returns the itinerary detail you need to triage.

Gotchas

• Read-only: this bundle does not create or cancel bookings. Send users to the Navan Admin UI for any mutation.
• Booking type values depend on what is enabled in the workspace. Common values are flight, hotel, car, rail. Unknown values return an empty page rather than an error.
• Default page size is 10 — small. Set size explicitly when sweeping a workspace; expect Navan to cap it (usually around 100).
• EU workspaces use a different Navan API region. If a credential validates in one region but calls fail in another, the workspace is likely region-mismatched.
• Self-service signup is enterprise-gated — the bundle is only useful to workspaces that already have a Navan admin account. The directory listing surfaces this caveat so users without access do not waste time on the credential form.
