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 OrgX MCP server's 29 tool definitions consume 24,130 tokens — 12% of a 200k context window, and 13× the median MCP server (1,901 tokens). A scoped grant exposing only the tools you use cuts that roughly in proportion.
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: OrgX ranks #39 of 3,219 measured MCP servers by definition cost. The median is 1,901 tokens, p90 is 7,953, and the heaviest (Fusionauth) is 183,337 — 92% of a 200k window on its own.
Each row is one tool definition as a tools/list entry — name, description and
input schema — counted with o200k_base. Average: 832 tokens per tool.

You don't need all 29 of those definitions in the window. PolicyLayer is an MCP gateway that sits in front of OrgX: 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 29 tools (no gateway) | 24,130 tokens | — |
| 3 granted tools | ~2,496 tokens | −90% |
| 5 granted tools | ~4,160 tokens | −83% |
| 10 granted tools | ~8,321 tokens | −66% |
The risk dividend: 1 of these 29 tools are critical-risk (destructive or financial) and cost 1,287 tokens (5% of the definition load). Block them — the recommended starter policy — and you reclaim that context before tuning anything else.

Its 29 tool definitions total 24,130 tokens — 12% of a 200k context window — measured with tiktoken o200k_base over the serialised tools/list payload. Exact counts vary slightly by client and model.
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.
Expose fewer tools. A PolicyLayer grant scopes OrgX 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 2,496 tokens, a 90% reduction.
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.
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.

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.

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