Install Agon Protocol in Claude Code, Cursor or VS Code

Runs npx -y @agonx402/protocol-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Ryvo Agentic Tools

Agent-facing tools for discovering, authenticating, and calling Ryvo Gateway routes.

One-Step Setup

setup --target all is the one command that installs everything Ryvo agents need:

  • Bundled skills into ~/.agents/skills, ~/.codex/skills, ~/.claude/skills.
  • Default SIWX signer wallet at ~/.ryvo/wallets/default.json.
  • Global CLI bins on PATH: Ryvo, ryvo-gateway, ryvo-wallet, ryvo-protocol (via npm install -g @ryvonetwork/gateway-cli @ryvonetwork/agent-wallet @ryvonetwork/protocol-cli).
  • Local agent reference at ~/.ryvo/llm.txt.
  • Ryvo MCP server registration for Codex, Claude Desktop, Claude Code, Cursor, Windsurf, and a generic config (existing entries preserved, backups written).
npx -y @ryvonetwork/agentic@latest setup --target all

After it finishes, restart your agent client and the agent can call Ryvo directly via:

  • The Ryvo MCP tools (ryvotokenquote, ryvotokenresolve, ryvotokenchart, ryvotokensearch, ryvotokenbatchquote, ryvogatewaycall, ryvogatewayauthcall, ...).
  • The bare CLIs: ryvo -p bitcoin, ryvo quote bitcoin solana usdt, ryvo-gateway auth call GET ..., etc.

Opt-out flags:

  • --skip-global-cli — do not run npm install -g. Bare CLI bins will not be on PATH; use npx -y @ryvonetwork/gateway-cli ... instead.
  • --skip-wallet-setup — only valid for install-skills when another signer wallet is already configured.

Supported setup targets:

npx -y @ryvonetwork/agentic setup --target codex            # ~/.codex/config.toml
npx -y @ryvonetwork/agentic setup --target claude-desktop   # standalone Claude Desktop GUI app config
npx -y @ryvonetwork/agentic setup --target claude-code      # ~/.claude.json (Claude Code CLI agent)
npx -y @ryvonetwork/agentic setup --target cursor           # ~/.cursor/mcp.json
npx -y @ryvonetwork/agentic setup --target windsurf
npx -y @ryvonetwork/agentic setup --target generic          # ~/.ryvo/mcp.json
npx -y @ryvonetwork/agentic setup --target all --dry-run

--target all writes to every adapter listed above. Claude Desktop (the standalone macOS/Windows GUI app) and Claude Code (the terminal CLI agent) read MCP servers from different files; --target all registers in both. After setup, restart your agent client so it re-reads the MCP server list.

Setup creates ~/.ryvo/wallets/default.json. @ryvonetwork/agent-wallet only signs Tokens API SIWX challenges (sign-in-with-x). For Gateway routes that require x402 exact payment or other auth, set RYVOSIGNERCOMMAND to a signer that returns PAYMENT-SIGNATURE / X-PAYMENT.

When RYVOSIGNERCOMMAND runs

  • Gateway MCP: only when calling ryvogatewayauthcall and the gateway responds with HTTP 402. The MCP spawns RYVOSIGNERCOMMAND once, piping the normalized auth-request JSON to stdin (same shape as ryvogatewayprepareauth). The process must exit 0 and print JSON to stdout: auth headers, or SIWX fallback (address, signature, optional signatureEncoding).
  • gateway-cli: ryvo-gateway auth call and batch reuse the same requestGateway path: after any 402 from the Gateway, RYVOSIGNERCOMMAND (or --auth-driver) runs if set. auth prepare / doctor never spawn the signer.

On Windows, when the signer command begins with npx/npm/pnpm/yarn, Node may run it via cmd shell. Treat RYVOSIGNERCOMMAND as equivalent to trusting a shell snippet if an attacker controls it.

Skills And Wallet

Install all Ryvo skills into every supported agent skill directory (~/.agents/skills, ~/.codex/skills, ~/.claude/skills), and create the default convenience wallet used for SIWX/auth calls:

npx -y @ryvonetwork/agentic install-skills
