What its tools let an agent do: 13 read

Install Dex Data in Claude Code, Cursor or VS Code

Runs npx -y dex-data-mcp on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add dex-data -- npx -y dex-data-mcp
Add to Cursor

What the publisher says

From the Dex Data repository's README, as published. We do not edit it. Read it on GitHub

dex-data MCP server

For an agent

Everything you need to decide whether to call this server, and what it will cost, is in this section. Read no further unless a human is asking.

Install

claude mcp add dex-data -- npx -y dex-data-mcp

Or, for any MCP host that reads a JSON config:

{ "mcpServers": { "dex-data": { "command": "npx", "args": ["-y", "dex-data-mcp"] } } }

Cost model

The first 25 calls each day are free on every tool. No wallet, no signup, no API key, no account. The free answer is the full answer — nothing is stubbed, truncated or degraded. What the free tier limits is how many calls you make, not what is in them.

After 25 calls in a day, a tool returns a payment challenge instead of an answer. If — and only if — a wallet is configured, this server settles that challenge in USDC on Base and returns the answer. With no wallet it tells you the price and spends nothing.

Environment

The default ceiling is $0.05, which is exactly the dearest tool here. Lower it below that and the $0.05 tools stop working — deliberately, and they say so.

The cap, and what "fails closed" means

Every paid call passes the same four gates, in this order, and any one of them refuses without paying:

not treated as free or as cheap; it is treated as unknown, and unknown does not get paid.

  1. No wallet → never pays. This is the state you are in unless someone set a key.
  2. Price unreadable → refuses. A challenge whose amount cannot be parsed is
  1. Price above DEXMAXPRICEUSD** → refuses, and names the price and the cap.
  2. Would cross DEXMAXSPENDUSD or DEXMAXCALLS** → refuses.

Accounting is in integer micro-USD, so a $1.00 budget at $0.05 a call buys exactly 20 calls and not 19 — floating-point drift cannot quietly close the budget early.

Call getspendbudget before any loop over paid tools. It is free, local and makes no network call, and it returns what has been spent and every cap in force.

Tools

Thirteen tools. Twelve fetch from the gateway; one is local. Each of the twelve targets exactly one route, and together they are exactly the routes the storefront lists — there is no hidden catalogue and no tool pointing at something that was withdrawn.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
