// MCP TOKEN COST

The Lodi Kids Activities MCP server costs 5,189 tokens before the first call.

Connect Lodi Kids Activities and its 72 tool definitions are loaded into the model's context on every request — 2.6% of a 200k window spent before your agent does anything.

QUICK ANSWER The Lodi Kids Activities MCP server's tool definitions consume 5,189 tokens — 2.7× 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: Lodi Kids Activities ranks #1011 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 5,189 tokens go.

Each row is one tool definition as a tools/list entry — name, description and input schema — counted with o200k_base. Average: 72 tokens per tool.

// SCOPED GRANT

Most agents use a handful of these tools. They pay for all 72.

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 (72 tokens each).

Grant scope	Definition cost	Reduction
All 72 tools (no gateway)	5,189 tokens	—
3 granted tools	~216 tokens	−96%
5 granted tools	~360 tokens	−93%
10 granted tools	~721 tokens	−86%

//FAQ

Lodi Kids Activities token-cost questions.

How many tokens does the Lodi Kids Activities MCP server use?+

Its 72 tool definitions total 5,189 tokens — 2.6% 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 Lodi Kids Activities 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 Lodi Kids Activities's token usage?+

Expose fewer tools. A PolicyLayer grant scopes Lodi Kids Activities 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 216 tokens, a 96% 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 72 catalogued Lodi Kids Activities tools. Counts refresh with every site build.

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

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