// MCP TOKEN COST

The Vacation Rentals MCP server costs 5,687 tokens before the first call.

Connect Vacation Rentals and its 64 tool definitions are loaded into the model's context on every request — 2.8% of a 200k window spent before your agent does anything.

QUICK ANSWER The Vacation Rentals MCP server's tool definitions consume 5,687 tokens — 3.0× the median MCP server (1,905 tokens). A scoped grant exposing only the tools you use cuts that roughly in proportion.

// CONTEXT WINDOW SHARE

What that buys before your agent starts working.

Tool definitions are overhead: they occupy context on every request and compete with your code, documents and conversation history for the same window.

Corpus context: Vacation Rentals ranks #976 of 3,213 measured MCP servers by definition cost. The median is 1,905 tokens, p90 is 7,952, and the heaviest (Fusionauth) is 183,337 — 92% of a 200k window on its own.

// PER-TOOL BREAKDOWN

Where the 5,687 tokens go.

Each row is one tool definition as a tools/list entry — name, description and input schema — counted with o200k_base. Average: 89 tokens per tool.

// SCOPED GRANT

Most agents use a handful of these tools. They pay for all 64.

A PolicyLayer grant exposes only the tools you allow — ungranted definitions are filtered out of the tool list, so they never enter the context window. Estimates below assume typical-weight tools (89 tokens each).

Grant scope	Definition cost	Reduction
All 64 tools (no gateway)	5,687 tokens	—
3 granted tools	~267 tokens	−95%
5 granted tools	~444 tokens	−92%
10 granted tools	~889 tokens	−84%

Model your own stack in the token-cost calculator, or see the Vacation Rentals policy for what a sensible grant looks like.

//FAQ

Vacation Rentals token-cost questions.

How many tokens does the Vacation Rentals MCP server use?+

Its 64 tool definitions total 5,687 tokens — 2.8% of a 200k context window — measured with tiktoken o200k_base over the serialised tools/list payload. Exact counts vary slightly by client and model.

Why does Vacation Rentals consume tokens before I send a message?+

MCP clients load every connected server's tool definitions — name, description, and input schema — into the model's context so it knows what it can call. That payload is charged against your context window on every request, whether or not a tool is used.

How do I reduce Vacation Rentals's token usage?+

Expose fewer tools. A PolicyLayer grant scopes Vacation Rentals to only the tools you allow — ungranted definitions are filtered out of the tool list, so they never enter the context window. A grant of 3 typical tools costs roughly 267 tokens, a 95% reduction.

Does deferred tool loading fix this?+

Partially, in some clients. Claude Code defers MCP tool schemas behind a tool-search step by default, and VS Code has experimental grouping — but you still pay tokens per search and reload, and Cursor, Windsurf and Gemini CLI load definitions upfront. Reducing the exposed tool set cuts the cost in every client.

// METHOD & REVIEW

How these numbers were measured.

Serialisation

Each tool is serialised as a tools/list entry — name, description, input schema — from the schemas in the PolicyLayer scan database. Clients differ slightly in framing, so treat counts as close estimates.

Tokeniser

tiktoken o200k_base (GPT-4o/o-series). Anthropic's current tokeniser isn't published, so Claude's exact counts will differ; for English text and JSON schemas the totals are close enough to treat these as estimates.

Deferred loading

Some clients now defer schema loading (Claude Code's tool search; VS Code experimental grouping). You still pay per search and reload — and Cursor, Windsurf and Gemini CLI load everything upfront.

Computed 07-06-2026 from the PolicyLayer scan database over all 64 catalogued Vacation Rentals tools. Counts refresh with every site build.

Expose only the tools you use — the rest never enter your context.

A PolicyLayer grant scopes Vacation Rentals to the tools you actually allow. Ungranted definitions never load, and every call that does run is checked against policy first.
