// MCP TOKEN COST

The Financial Modeling Prep (FMP) Server MCP server costs 25,532 tokens before the first call.

Connect Financial Modeling Prep (FMP) Server and its 253 tool definitions are loaded into the model's context on every request — 13% of a 200k window spent before your agent does anything.

QUICK ANSWER The Financial Modeling Prep (FMP) Server MCP server's tool definitions consume 25,532 tokens — 24× the median MCP server (1,075 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.

// SCOPED GRANT

Most agents use a handful of these tools. They pay for all 253.

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 (101 tokens each).

Grant scope	Definition cost	Reduction
All 253 tools (no gateway)	25,532 tokens	—
3 granted tools	~303 tokens	−99%
5 granted tools	~505 tokens	−98%
10 granted tools	~1,009 tokens	−96%

Model your own stack in the token-cost calculator, or see the Financial Modeling Prep (FMP) Server policy for what a sensible grant looks like.

//FAQ

Financial Modeling Prep (FMP) Server token-cost questions.

How many tokens does the Financial Modeling Prep (FMP) Server MCP server use?+

Its 253 tool definitions total 25,532 tokens — 13% 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 Financial Modeling Prep (FMP) Server 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 Financial Modeling Prep (FMP) Server 's token usage?+

Expose fewer tools. A PolicyLayer grant scopes Financial Modeling Prep (FMP) Server 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 303 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.
