About Instructions

Instructions is an MCP server in the Social category: shared MCP server instructions for the OpenDexter / Dexter x402 Gateway. Single source of truth consumed by both the hosted server (open.dexter.cash/mcp) and the npm-installable local server (@dexterai/opendexter).

Install

Claude Code
claude mcp add instructions -- npx -y @dexterai/mcp-instructions
npx
npx -y @dexterai/mcp-instructions

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

    }
  }

What This Plugin Does

This plugin ships with a real MCP server that gives your agent live tools for searching, paying for, and calling paid APIs. On top of that, it has deep SDK knowledge so the agent can help you build x402 payments into your own projects.

After installing, your agent can immediately:

  • Search the Dexter Marketplace for any paid API (image generation, DeFi, analytics, AI, games — thousands of endpoints)
  • Check what an API costs before paying
  • Pay and call any x402 API with automatic USDC settlement
  • Help you build x402 clients, servers, React apps, Stripe integrations, and access passes

What is x402?

x402 is an open protocol for machine-to-machine payments over HTTP. When an API returns 402 Payment Required, it includes payment instructions. The client pays (USDC on Solana, Base, or other chains), and the API delivers the response. No API keys, no subscriptions, no invoices.

Dexter operates the most-used x402 facilitator at https://x402.dexter.cash, processing millions of settlements across thousands of indexed endpoints from every major x402 facilitator — Dexter, Coinbase, PayAI, and more.

Plugin Contents

MCP Server — @dexterai/opendexter

Seven tools cover everything:

Tool Description
x402_search Semantic capability search over thousands of paid APIs. Returns tiered results (strong + related matches) ranked by quality, usage, and reputation.
x402_check Preview pricing per chain without spending anything. See exactly what an API costs before committing.
x402_fetch Call any x402 API with automatic USDC payment. Signs, pays, retries — returns the response directly with an on-chain settlement receipt.
x402_pay Alias for x402_fetch.
x402_access Access identity-gated endpoints with wallet proof (Sign-In-With-X).
x402_wallet Show wallet address, USDC/SOL balances, and deposit instructions.
x402_settings Read or update your per-call spending limit.

Two wallets are auto-created at ~/.dexterai-mcp/wallet.json on first run — one Solana, one EVM. Fund either address with USDC and your agent can start paying for APIs immediately.

Skills (6)

Deep knowledge the agent invokes when relevant:

Skill What it teaches
opendexter How to use the x402 tools: search → check → fetch workflow, quality scores, funding flows, error recovery
x402-client Build x402 clients: wrapFetch(), createX402Client(), Budget Accounts for agents, Sponsored Access, keypair wallets, access passes
x402-server Add x402 paywalls: x402Middleware() with multi-chain accept, Stripe PayTo, dynamic/token pricing, access passes, sponsored access injection
x402-react React hooks: useX402Payment() (payment state, balances, tx info), useAccessPass() (tier discovery, purchase, auto-fetch)
x402-protocol v2 spec: core types, payment flow, 3 schemes (exact, upto, bridge), HTTP/MCP/A2A transports, all CAIP-2 networks, error codes
x402-debugging Diagnose failures: 27 SDK error codes, facilitator health, fee payer safety, retry support, pre-payment callbacks

Rules (2, always-on)

Injected into every conversation so the agent always knows the fundamentals:

  • x402-protocol — CAIP-2 network identifiers, header conventions, atomic units, facilitator URL, supported chains
  • x402-coding — Import from subpaths (@dexterai/x402/client), prefer wrapFetch() for agents, x402Middleware() for servers

Agent

  • x402-engineer — Specialized persona that knows the full Dexter x402 stack. Validates amounts and balances before payment, never exposes private keys, reaches for x402_search whenever a user mentions paid APIs.
