MCP server for Agon Protocol state reads and prepare-only payment-channel actions.
Overview
Local MCP server for Agon Protocol that lets an assistant read protocol state and prepare, but not sign or send, payment-channel actions on Solana devnet.
- What you can do
- Read Agon Protocol state such as token registry and program configuration on Solana devnet, using the configured program ID and USDC token ID defaults or overrides from environment variables. Prepare payment-channel actions for review without signing or broadcasting transactions. The manifest lists no individual tools, so exact tool names are not documented here.
- When to use it
- Useful when an assistant needs to inspect Agon Protocol devnet state or draft payment-channel operations for a human to review and sign elsewhere. Not intended for mainnet or for automated signing and sending of transactions.
- Requirements
- Runs as a local stdio process installed from the npm package @agonx402/protocol-mcp, so Node.js and npm are needed. Optional environment variables AGON_PROTOCOL_DEVNET_USDC_TOKEN_ID, AGON_PROTOCOL_PROGRAM_ID and SOLANA_DEVNET_RPC_URL configure the token, program and RPC endpoint; the program ID defaults to the live devnet deployment. Network access to Solana devnet is required. No authentication is declared.
Installation
In SourceWeft
- Open Agon Protocol in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

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(vianpm 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).
After it finishes, restart your agent client and the agent can call Ryvo directly via:
- The Ryvo MCP tools (
ryvo_token_quote,ryvo_token_resolve,ryvo_token_chart,ryvo_token_search,ryvo_token_batch_quote,ryvo_gateway_call,ryvo_gateway_auth_call, ...). - 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 runnpm install -g. Bare CLI bins will not be on PATH; usenpx -y @ryvonetwork/gateway-cli ...instead.--skip-wallet-setup— only valid forinstall-skillswhen another signer wallet is already configured.
Supported setup targets:
--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 RYVO_SIGNER_COMMAND to a signer that returns PAYMENT-SIGNATURE / X-PAYMENT.
When RYVO_SIGNER_COMMAND runs
- Gateway MCP: only when calling
ryvo_gateway_auth_calland the gateway responds with HTTP 402. The MCP spawnsRYVO_SIGNER_COMMANDonce, piping the normalized auth-request JSON to stdin (same shape asryvo_gateway_prepare_auth). The process must exit 0 and print JSON to stdout: auth headers, or SIWX fallback (address,signature, optionalsignatureEncoding). gateway-cli:ryvo-gateway auth callandbatchreuse the samerequestGatewaypath: after any 402 from the Gateway,RYVO_SIGNER_COMMAND(or--auth-driver) runs if set.auth prepare/doctornever spawn the signer.
On Windows, when the signer command begins with npx/npm/pnpm/yarn, Node may run it via cmd shell. Treat RYVO_SIGNER_COMMAND 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:
Other install targets:
Use --skip-wallet-setup only when another signer wallet is already configured. The installer copies only the Ryvo skill folders, creates the target directory if needed, and overwrites only these Ryvo-owned skill names:
ryvo-gatewayryvo-protocolryvo-gateway-payment-channels
install-skills installs skills and creates ~/.ryvo/wallets/default.json. setup performs skills, wallet, and MCP registration.
After setup --target all, the CLI bins are on PATH. Use them directly:
If a bare bin is not on PATH (you ran setup --skip-global-cli, the global install hit a permission error, or you have not run setup yet), the same calls work via npx -y @ryvonetwork/gateway-cli ..., npx -y @ryvonetwork/agent-wallet ..., and npx -y @ryvonetwork/protocol-cli .... The MCP server entries also use npx -y, so you do not need a global install for MCP tools to work.
Ryvo Gateway should be the first source for API calls covered by the live catalog at https://gateway.ryvo.network/v1/catalog. Tokens API supports market data for crypto, currencies, treasuries, ETFs, metals, stocks, and their Solana token variants. Agents should use high-level Gateway CLI commands for common Tokens pulls (quote, price, volume, liquidity, mcap, search, resolve, curated, profile, variants, markets, tickers, risk, chart, ohlcv, snapshots) before raw route strings, and label whether values came from canonicalMarket, stats, primaryVariant.market, profile.data, tickers, or candles.
MCP servers are separate packages:
RYVO_PAYMENT_MAX_AMOUNT_USD and RYVO_PAYMENT_DAILY_LIMIT_USD are optional: some x402 auth-prep responses include them for human review; ryvo-wallet does not enforce them.
Payment-channel flows are devnet-only in v1. Tokens SIWX routes do not use payment channels. Gateway auth drivers are wallet-agnostic helper commands. The Gateway CLI sends normalized auth request JSON to the driver over stdin and accepts returned headers or SIWX address/signature JSON over stdout. Drivers can wrap browser wallets, local keypairs, MPC, custody systems, x402 payment services, or Ryvo channel commitment builders. The Ryvo CLI/MCP packages do not keep keys or mutate wallet/MCP configuration.
Generic authenticated call flow:
- Use a known endpoint or fetch
/v1/catalogto discover one. - Send the exact request and receive a
402challenge. - Pass the normalized auth request to
RYVO_SIGNER_COMMAND. - Retry the exact same request with returned
SIGN-IN-WITH-X,PAYMENT-SIGNATURE,X-PAYMENT, or channel headers.
Gateway MCP exposes ryvo_gateway_auth_call for this flow. Low-level prepare/complete/call tools remain available for agents with their own wallet policies.

Quick Checks
The CLI and MCP server use RYVO_SIGNER_COMMAND when configured. The bundled agent wallet is replaceable; external wallets can return headers or signatures through the same hook.
The protocol CLI and MCP server are read + prepare only; they do not sign or broadcast transactions.
