In plain words
What is it for?
Use them to check wallet readiness and balances, view assets, find deposit details, and handle supported send, buy, sell, payment, and wallet-gated API requests.
Why use it?
They provide the required order of wallet checks and authentication steps for financial actions while keeping the supported hosted workflow separate from the local version.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

opendexter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 246 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenDexter

OpenDexter is Dexter's hosted financial-action layer at https://open.dexter.cash/mcp. Native MCP OAuth binds the current client session to the user's Dexter Wallet. The model receives no private key or passkey.

This is the canonical hosted OpenDexter workflow shared by ChatGPT, Codex, and Claude Code. Keep every live capability and complete user journey available here in this guide as the product grows. Feature sections below are parts of that one guide, not separate Buy, Sell, Send, credit, wallet, or recovery micro-skills.

Use the current client's native Connect or MCP login action described in references/authentication.md. Do not substitute local npm-proxy commands or advertise a capability that the hosted tool roster does not ship. The local seven-tool npm/stdio edition is intentionally a separate workflow. OAuth must complete before MCP initialization and tool discovery. Every hosted tool uses the same vault OAuth scope.

Recognize ordinary requests

  • "Do I have a Dexter Wallet?", "what is my balance?", or "where can I add funds?": call dexter_wallet first.
  • "What is in my wallet?", "what can I do with my assets?", or "what can I send, buy, or sell?": call dexter_wallet first, then dexter_wallet_portfolio. Compose cash/readiness and asset inventory without treating either as execution authority.
  • "What can Indexter do?", "show me Apify offerings", or "find an API for this job": call indexter_search once with the complete request. Discovery never pays and does not require a separate wallet call.
  • "What will this API cost?" or a known paid URL: call x402_check; checking is not permission to pay. If the exact check is not GET, explain that it may submit the request to the provider and obtain explicit confirmation first.
  • "Pay for/call this API": discover or check first, disclose the exact terms, and use the purchase flow below. Never infer approval from the request alone when exact seller, request, or ceiling is missing.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
