Overview

AI-generated overview

Read-only remote MCP server for US backcountry permit and campground rules, dates and recorded site openings, with links to official booking pages.

What you can do
  • Search US backcountry and wilderness permits by name, park, trail or area, and read one permit's rules, season, lottery and release dates, closures and group limits.
  • Search campgrounds across Recreation.gov and state park booking systems, and read one campground's booking system, sale window, site count, stay limits and season.
  • Check recorded availability for a permit or campground over up to 62 days, with a state per date.
  • Get the official booking link for a permit or campground, optionally carrying a first date and group size.
When to use it
Useful when planning US hiking, climbing, river or overnight trips and you need to know which permit a trip requires, when applications or lotteries open, or whether a site has recently been seen opening. Also handy for campground research before booking.
Requirements
Remote streamable HTTP endpoint; no sign-in, API key, environment variables or headers are declared. Network access to the endpoint is needed.
Before you install
Availability comes from PermitSnag's own stored checks of booking sites, not a live look, so states may be stale. Nothing is booked and no payment is involved; the returned booking links lead to official agency pages where dates and group size must be confirmed.

Installation

In SourceWeft

  1. Open PermitSnag in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.permitsnag%2Fpermits/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

search_permits

Search US backcountry and wilderness permits

Find US backcountry and wilderness permits by name, park, trail or area, for hikes, climbs, river trips and overnight trips in national parks, national forests and state parks. Use this when someone asks how to get a permit or which permit a trip needs. Returns up to 10 permits with their PermitSnag page and whether PermitSnag scans them for cancellation openings. It does not check dates; use check_availability for that, and get_permit_details for the rules of one permit.

Parameterslimitqueryrequiredstate

get_permit_details

US backcountry permit rules and dates

Get the rules for one US backcountry or wilderness permit: how it is issued (reservation, lottery or in person), its season, lottery and release dates, closures, group size limit, and the official agency page. Use it after search_permits, or when the person names a specific permit. Every date comes from an agency source; a date we cannot source is left out. Says whether PermitSnag can send an alert when the permit opens.

Parameterspermitrequired

search_campgrounds

Search US campgrounds

Find campgrounds in the US by name, area or state, across Recreation.gov and state park booking systems. Use this when someone wants a place to camp or asks about a specific campground. Returns up to 10 campgrounds with their PermitSnag page, their booking system, and whether PermitSnag can send an alert when a site opens. It does not check dates; use check_availability for that.

Parameterslimitqueryrequiredstate

get_campground_details

US campground details

Get the details of one US campground: its booking system, how far ahead sites go on sale, site count and types, stay limits, season and closures. Use it after search_campgrounds, or when the person names a specific campground. Says whether PermitSnag can send an alert when a site opens, and whether our checks count individual sites or only the campground as a whole.

Parameterscampgroundrequired

check_availability

Check recorded openings for a permit or campground

Shows what PermitSnag has recorded for one US backcountry permit or one campground over a range of up to 62 days. Answers come from PermitSnag's own stored checks of the booking site, not a live look, and nothing is booked. Each date has one state: observed_opening (an opening seen recently, with when it was last seen), observed_no_match (a recent check that saw no opening, with its time), stale (the newest check is older than staleAfterHours, with its time), unknown (no usable check of that date), unreleased (not on sale yet, by the agency's release rule or the booking site), off_season (outside the agency's published season), closed (closed by the agency) or unsupported (PermitSnag does not check this place). Neither stale nor unknown means sold out. Permit dates are shown as they stood 15 minutes ago. For a permit split into zones or entry points, our checks may cover only some of them, so a date with no opening seen comes back as unknown, never as observed_no_match.
