// MCP TOKEN COST

The SimplyPrint: 3D Print Farm Management MCP server costs 9,531 tokens before the first call.

Connect SimplyPrint: 3D Print Farm Management and its 70 tool definitions are loaded into the model's context on every request — 4.8% of a 200k window spent before your agent does anything.

QUICK ANSWER The SimplyPrint: 3D Print Farm Management MCP server's tool definitions consume 9,531 tokens — 5.0× 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.

200K WINDOW 4.8%

1M WINDOW 1.0%

Corpus context: SimplyPrint: 3D Print Farm Management ranks #183 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 9,531 tokens go.

Each row is one tool definition as a tools/list entry — name, description and input schema — counted with o200k_base. Average: 136 tokens per tool.

// SCOPED GRANT

Most agents use a handful of these tools. They pay for all 70.

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 (136 tokens each).

Grant scope	Definition cost	Reduction
All 70 tools (no gateway)	9,531 tokens	—
3 granted tools	~408 tokens	−96%
5 granted tools	~681 tokens	−93%
10 granted tools	~1,362 tokens	−86%

Model your own stack in the token-cost calculator, or see the SimplyPrint: 3D Print Farm Management policy for what a sensible grant looks like.

//FAQ

SimplyPrint: 3D Print Farm Management token-cost questions.

How many tokens does the SimplyPrint: 3D Print Farm Management MCP server use?+

Its 70 tool definitions total 9,531 tokens — 4.8% 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 SimplyPrint: 3D Print Farm Management 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 SimplyPrint: 3D Print Farm Management's token usage?+

Expose fewer tools. A PolicyLayer grant scopes SimplyPrint: 3D Print Farm Management 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 408 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 70 catalogued SimplyPrint: 3D Print Farm Management tools. Counts refresh with every site build.

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

A PolicyLayer grant scopes SimplyPrint: 3D Print Farm Management to the tools you actually allow. Ungranted definitions never load, and every call that does run is checked against policy first.
