Common questions

Is SkyAccess safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.3) reached the registry 31 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

SkyAccess MCP server

SkyAccess is the world's largest empty leg marketplace by listing volume. This free, public MCP server lets any AI assistant search 5,000+ live empty leg flights from 900+ FAA Part 135 (and international equivalent) certified charter operators, often 25 to 75% below a comparable full charter. It also returns indicative charter price estimates and a booking link the traveler can open.

Use the hosted endpoint. Nothing needs to be installed.

https://mcp.skyaccess.com/mcp

Install

Each option below adds the hosted endpoint to your client. Nothing runs on your machine, and there is no account, sign-up or API key.

Claude Code:

  claude mcp add --transport http skyaccess https://mcp.skyaccess.com/mcp

Claude Code plugin (the same server, plus a skill that tells Claude when to use each tool):

  claude plugin marketplace add sky-access/skyaccess-mcp

claude plugin install skyaccess@skyaccess

Gemini CLI:

  gemini extensions install https://github.com/sky-access/skyaccess-mcp

VS Code (GitHub Copilot): use a button above, or run:

  code --add-mcp '{"name":"skyaccess","type":"http","url":"https://mcp.skyaccess.com/mcp"}'

Claude (claude.ai and Claude Desktop), Cursor and other clients: see Connect from an MCP client.

Other clients

This repository also ships a package for each client below. Each one points at the same hosted endpoint and runs nothing on your machine.

Kiro

In the Powers panel choose Add Custom Power, then Import power from GitHub, and enter https://github.com/sky-access/skyaccess-mcp. The power in powers/skyaccess adds the server and a skill that tells the Kiro agent when to use each tool.

Gemini CLI

gemini extensions install https://github.com/sky-access/skyaccess-mcp

The extension is defined in gemini-extension.json and GEMINI.md.

Google Antigravity

Add the server to ~/.gemini/config/mcp_config.json, or to .agents/mcp_config.json in a workspace. Antigravity reads serverUrl, not url:

{ "mcpServers": { "skyaccess": { "serverUrl": "https://mcp.skyaccess.com/mcp" } } }

Or install the plugin folder from a clone of this repository with /plugin install /integrations/antigravity/skyaccess. See integrations/antigravity/skyaccess.

GitHub Copilot CLI

copilot plugin marketplace add sky-access/skyaccess-mcp

copilot plugin install skyaccess@skyaccess

This installs plugins/skyaccess, which carries an Agent Plugins plugin.json and mcp.json for Copilot next to the Claude Code manifests.

Connection details


Endpoint	`https://mcp.skyaccess.com/mcp`
Authentication	None. The server is free and anonymous: no account, sign-up, API key or OAuth.
Transport	Streamable HTTP, `POST` only, stateless. No `Mcp-Session-Id` is issued, so every request stands alone. `GET` returns `405` by design.
Required headers	`Content-Type: application/json`. `Accept` can be the MCP spec value `application/json, text/event-stream`, `application/json` alone, `/`, or left out. An `Accept` value that does not list `application/json` and is not just `/` (for example `text/html` or `text/event-stream` alone) returns `406`.
Response format	With `Accept: application/json, text/event-stream`, each reply is one Server-Sent Events message: `event: message`, then `data:` followed by the JSON-RPC response. With `application/json` alone, `/` or no `Accept` header, each reply is plain JSON (`Content-Type: application/json`).
Protocol version	`2025-06-18`. `2025-11-25`, `2025-03-26` and `2024-11-05` are also negotiated.
Rate limits	Tool calls: 30 requests per 60 seconds per client IP. Connection setup is not counted. `request_booking`: 10 charter enquiries per hour per client IP. See Rate limits.
Coverage	Global inventory, most of it in the United States. Prices and estimates are in USD.
Payments	None. No tool takes a payment or has a payment field.
Support	contact@skyaccess.com
Privacy policy	https://skyaccess.com/privacy#connector
Terms of service	https://skyaccess.com/terms

Connect from an MCP client

Any client that supports remote MCP servers over Streamable HTTP can use the endpoint directly. Leave authentication empty.

Claude (claude.ai and Claude Desktop): Settings, Connectors, Add custom connector, then paste https://mcp.skyaccess.com/mcp.
Claude Code, Gemini CLI and VS Code: see Install.
Cursor: add this to ~/.cursor/mcp.json:

  { "mcpServers": { "skyaccess": { "url": "https://mcp.skyaccess.com/mcp" } } }

VS Code, by hand: add this to .vscode/mcp.json in your workspace:

  { "servers": { "skyaccess": { "type": "http", "url": "https://mcp.skyaccess.com/mcp" } } }

Clients that only speak stdio (for example Claude Desktop's claude_desktop_config.json file): use the bridge in this repository. See Local installer and stdio bridge.

Try it with curl

List the tools:

curl -sS https://mcp.skyaccess.com/mcp \

-H 'Content-Type: application/json' \ -H 'Accept: application/json, text/event-stream' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Search empty legs (read-only):

curl -sS https://mcp.skyaccess.com/mcp \

-H 'Content-Type: application/json' \ -H 'Accept: application/json, text/event-stream' \ -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"search_empty_legs","arguments":{"origin":"Los Angeles","destination":"Las Vegas","passengers":4}}}'

The server is stateless, so both commands work without an initialize handshake. MCP clients still send one, and the server answers it normally.

Tools

Tool	Type	What it does
`search_empty_legs`	Read-only	Searches live empty leg flights by `origin`, `destination`, `departureDateFrom`, `departureDateTo`, `passengers` and `max_price` (USD), all optional. Returns up to 5 flights with route, departure time, whole-aircraft price (taxes and fees shown at checkout), aircraft, seats, amenities, `flightId` and a booking link.
`get_flight`	Read-only	Re-reads one flight by `flightId`, or says it is no longer available.
`booking_handoff`	Read-only	Returns the SkyAccess booking page link for a `flightId`. It creates, holds or changes nothing; the traveler reviews and books on the page.
`get_charter_estimate`	Read-only	Returns an indicative USD price range per aircraft category, with flight time, for a charter from `origin` to `destination` (optional `passengers` and `aircraftCategory`).
`request_booking`	Write	Sends the traveler's name, email and trip details (`origin`, `destination`, `departureDate`, `passengers`, optional `notes`) to SkyAccess. A SkyAccess specialist follows up by email shortly to confirm availability and price. It takes no payment and creates no booking.

A flight with price: null has no published price (SkyAccess shows it as "Contact for price"). Such flights can appear even when max_price is set, because their price is unknown.

Every tool carries MCP annotations: the four read-only tools set readOnlyHint: true, and request_booking sets readOnlyHint: false.

Example prompts

"Find me a private jet from Los Angeles to Las Vegas this week for 4 people." (search_empty_legs)
"Are there any cheap private jet flights from Miami to the Bahamas?" (search_empty_legs)
"Show me empty legs from Teterboro to Palm Beach and give me the booking link for the cheapest one." (search_empty_legs, then booking_handoff)
"How much would it cost to charter a private jet from Teterboro to Aspen for 6 people?" (get_charter_estimate)
"What private jet deals are leaving Dallas this weekend?" (search_empty_legs)
"Roughly what does a private jet from New York to London cost for 8 passengers?" (get_charter_estimate)

Inventory changes all the time, so the flights returned differ from run to run.

Data and privacy

The four read-only tools need no personal data. request_booking is the only tool that sends personal data: the name and email the traveler gives, plus the trip details and any notes, go to SkyAccess so a specialist can reply. Call it only when the traveler asks SkyAccess to contact them.

How SkyAccess handles this data: https://skyaccess.com/privacy#connector

Rate limits

Current limits, per client IP:

Tool calls: 30 requests per 60 seconds. Each request that carries a tools/call counts once. Connection setup is not counted: initialize, notifications/initialized, notifications/cancelled, tools/list, ping, and the GET an MCP client sends to open the optional SSE stream (answered 405). A typical client turn (connect, list tools, call one tool) therefore spends 1 request. Any other method counts, and so does a setup request that is over 8 KB, chunked or compressed, or a batch that repeats a setup method. Counted tool-call responses carry RateLimit-Policy: 30;w=60, RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset headers (a request_booking response carries the hourly limit's values instead); setup responses carry none.
10 charter enquiries per hour. Only requests that call request_booking count toward this limit.
Per request: a JSON-RPC batch may carry at most 4 tool calls, and at most 1 request_booking call. Larger batches return 400.

Over a limit, the server answers HTTP 429 with JSON-RPC error code -32029. The RateLimit-Reset header gives the seconds until the window resets; retry after that.

Troubleshooting

Symptom	Cause and fix
`406 Not Acceptable`	The `Accept` header does not list `application/json` and is not just `/` (for example `text/html` or `text/event-stream` alone). Send `Accept: application/json, text/event-stream`, `application/json` or `/`, or leave `Accept` out.
`429`, JSON-RPC error `-32029`	A rate limit was reached. "Max 30 requests per minute" is the tool-call limit (connection setup does not count toward it); "Max 10 booking submissions per hour" is the `request_booking` limit. Wait `RateLimit-Reset` seconds, then retry.
`405`	The request was a `GET`. Send JSON-RPC over `POST`. MCP clients send one `GET` to open an optional SSE stream and read the `405` as "no stream offered"; that is expected and does not count toward the rate limit.
`400` "Only one request_booking call is allowed per request" or "At most 4 tool calls are allowed per request"	Split the JSON-RPC batch into smaller requests.
"No published empty leg flight matches that id."	The flight is no longer published (booked, withdrawn or departed), or the id is wrong. Run `search_empty_legs` again.
