// MCP TOKEN COST

The metagraphed — Bittensor subnet operational registry MCP server costs 107,818 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 metagraphed — Bittensor subnet operational registry MCP server's 235 tool definitions consume 107,818 tokens — 54% of a 200k context window, and 53× the median MCP server (2,038 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.

Corpus context: metagraphed — Bittensor subnet operational registry ranks #6 of 6,689 measured MCP servers by definition cost. The median is 2,038 tokens, p90 is 12,122, and the heaviest (Ainumbers Mcp Apps) is 269,012 — 135% of a 200k window on its own. New to this? See MCP token cost and context window in the glossary.

// CUT THE COST

Your agent uses a handful of these tools. It pays for all 235.

You don't need all 235 of those definitions in the window. PolicyLayer is an MCP gateway that sits in front of metagraphed — Bittensor subnet operational registry: 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 235 tools (no gateway)	107,818 tokens	—
3 granted tools	~1,376 tokens	−99%
5 granted tools	~2,294 tokens	−98%
10 granted tools	~4,588 tokens	−96%

The risk dividend: 1 of these 235 tools are critical-risk (destructive or financial) and cost 206 tokens (0% 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 metagraphed — Bittensor subnet operational registry — 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

metagraphed — Bittensor subnet operational registry token-cost questions.

How many tokens does the metagraphed — Bittensor subnet operational registry MCP server use?+

Its 235 tool definitions total 107,818 tokens — 54% 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 metagraphed — Bittensor subnet operational registry 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 metagraphed — Bittensor subnet operational registry's token usage?+

Expose fewer tools. A PolicyLayer grant scopes metagraphed — Bittensor subnet operational registry 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 1,376 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.
