// MCP TOKEN COST

The Yaver MCP server costs 80,063 tokens before the first call.

Every request your agent makes carries every tool definition this server exposes — context your code, documents and conversation can't use, mostly for tools the agent never calls. You don't need them all in the window, and you don't have to pay for them.

QUICK ANSWER The Yaver MCP server's 1060 tool definitions consume 80,063 tokens — 40% of a 200k context window, and 42× the median MCP server (1,900 tokens). A scoped grant exposing only the tools you use cuts that roughly in proportion.

// CONTEXT WINDOW SHARE

What that costs 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 40%
1M WINDOW 8.0%

Corpus context: Yaver ranks #6 of 3,165 measured MCP servers by definition cost. The median is 1,900 tokens, p90 is 7,952, and the heaviest (Fusionauth) is 183,337 — 92% of a 200k window on its own. New to this? See MCP token cost and context window in the glossary.

// PER-TOOL BREAKDOWN

Where the 80,063 tokens go.

Each row is one tool definition as a tools/list entry — name, description and input schema — counted with o200k_base. Average: 76 tokens per tool.

// CUT THE COST

Your agent uses a handful of these tools. It pays for all 1060.

You don't need all 1060 of those definitions in the window. PolicyLayer is an MCP gateway that sits in front of Yaver: only the tools you grant are exposed to the agent, the rest never load. A smaller window means a sharper agent — less noise when it picks a tool — and every request costs less:

Grant scopeDefinition costReduction
All 1060 tools (no gateway) 80,063 tokens —
3 granted tools ~227 tokens −100%
5 granted tools ~378 tokens −100%
10 granted tools ~755 tokens −99%

The risk dividend: 46 of these 1060 tools are critical-risk (destructive or financial) and cost 3,584 tokens (4% of the definition load). Block them — the recommended starter policy — and you reclaim that context before tuning anything else.

  1. Create a free account and register Yaver — nothing to install.
  2. Grant only the tools you use — ungranted definitions never enter the context window.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

//FAQ

Yaver token-cost questions.

How many tokens does the Yaver MCP server use?+

Its 1060 tool definitions total 80,063 tokens — 40% 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 Yaver 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 Yaver's token usage?+

Expose fewer tools. A PolicyLayer grant scopes Yaver 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 227 tokens, a 100% 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.

01
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.

02
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.

03
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.

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

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