// MCP TOKEN COST

The GPT 5 5 x402 Low Cost Agent Tools MCP server costs 62,353 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 GPT 5 5 x402 Low Cost Agent Tools MCP server's 214 tool definitions consume 62,353 tokens — 31% of a 200k context window, and 33× the median MCP server (1,862 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.

// CUT THE COST

Your agent uses a handful of these tools. It pays for all 214.

You don't need all 214 of those definitions in the window. PolicyLayer is an MCP gateway that sits in front of GPT 5 5 x402 Low Cost Agent Tools: 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 scope	Definition cost	Reduction
All 214 tools (no gateway)	62,353 tokens	—
3 granted tools	~874 tokens	−99%
5 granted tools	~1,457 tokens	−98%
10 granted tools	~2,914 tokens	−95%

The risk dividend: 82 of these 214 tools are critical-risk (destructive or financial) and cost 30,807 tokens (49% of the definition load). Block them — the recommended starter policy — and you reclaim that context before tuning anything else.

Create a free account and register GPT 5 5 x402 Low Cost Agent Tools — nothing to install.
Grant only the tools you use — ungranted definitions never enter the context window.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

//FAQ

GPT 5 5 x402 Low Cost Agent Tools token-cost questions.

How many tokens does the GPT 5 5 x402 Low Cost Agent Tools MCP server use?+

Its 214 tool definitions total 62,353 tokens — 31% 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 GPT 5 5 x402 Low Cost Agent Tools 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 GPT 5 5 x402 Low Cost Agent Tools's token usage?+

Expose fewer tools. A PolicyLayer grant scopes GPT 5 5 x402 Low Cost Agent Tools 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 874 tokens, a 99% 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.
