// MCP TOKEN COST

The Srv D7aoqmh5pdvs7391dcqg MCP server costs 4,840 tokens before the first call.

Connect Srv D7aoqmh5pdvs7391dcqg and its 70 tool definitions are loaded into the model's context on every request — 2.4% of a 200k window spent before your agent does anything.

QUICK ANSWER The Srv D7aoqmh5pdvs7391dcqg MCP server's tool definitions consume 4,840 tokens — 2.5× 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: Srv D7aoqmh5pdvs7391dcqg ranks #1043 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 4,840 tokens go.

Each row is one tool definition as a tools/list entry — name, description and input schema — counted with o200k_base. Average: 69 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 (69 tokens each).

Grant scope	Definition cost	Reduction
All 70 tools (no gateway)	4,840 tokens	—
3 granted tools	~207 tokens	−96%
5 granted tools	~346 tokens	−93%
10 granted tools	~691 tokens	−86%

Model your own stack in the token-cost calculator, or see the Srv D7aoqmh5pdvs7391dcqg policy for what a sensible grant looks like.

//FAQ

Srv D7aoqmh5pdvs7391dcqg token-cost questions.

How many tokens does the Srv D7aoqmh5pdvs7391dcqg MCP server use?+

Its 70 tool definitions total 4,840 tokens — 2.4% 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 Srv D7aoqmh5pdvs7391dcqg 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 Srv D7aoqmh5pdvs7391dcqg's token usage?+

Expose fewer tools. A PolicyLayer grant scopes Srv D7aoqmh5pdvs7391dcqg 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 207 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 Srv D7aoqmh5pdvs7391dcqg tools. Counts refresh with every site build.

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

A PolicyLayer grant scopes Srv D7aoqmh5pdvs7391dcqg to the tools you actually allow. Ungranted definitions never load, and every call that does run is checked against policy first.
