Common questions

Is Ophis MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 19 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

@ophis/mcp-server

Agent-facing MCP server for the Ophis DEX, deployed as a Cloudflare Worker with the Streamable-HTTP transport at `https://mcp.ophis.fi/mcp`.

Current server release: v0.2.0, with 13 tools across 15 configured EVM chains (14 mainnets plus Sepolia).

It exposes the Ophis trading surface to autonomous agents and MCP clients without making them re-derive the fork's non-obvious, easy-to-get-wrong details (non-canonical settlement contracts on the Ophis-operated chains, the self -hosted Optimism, Unichain, Robinhood Chain, and Arc orderbook hosts, the CIP-75 partner-fee appData shape, and receiver pinning).

Arc (5042) charges the 1 bp base fee and supports routed-volume indexing and referral attribution. Server referral defaults apply; a per-call code overrides the default, and an empty string opts out. After an order is accepted, submit_order enrolls the owner for indexing and the live trade-rewards campaign.

The tools operate on configured EVM orderbooks. list_chains reports configuration, not a live availability probe. The standalone app's externally funded NEAR source flow is separate; these tools do not create or fund those deposits. See network and funding coverage.

Security model

The server holds no private keys and never signs. build_order returns a *bounded, ready-to-sign* EIP-712 payload with the order receiver pinned to the owner (the #1 autonomous-agent drain vector); the agent signs with its own key and submits. This is the V1 "bounded capability" pattern, an off-chain misuse guard, not an on-chain authorization boundary. It is public and unauthenticated: every backing endpoint is already public, and the tools are read/build-only.

Tools

Tool	Purpose
`parse_intent`	Plain-English swap request → structured intent (LibertAI Qwen via `swap.ophis.fi/api/intent`).
`resolve_token`	Resolve a token symbol to its canonical address from the trusted Ophis list; fails closed (anti-spoof).
`list_chains`	Supported chains, orderbook hosts, settlement contracts, partner-fee config.
`get_quote`	Best-execution quote from the chain's Ophis orderbook (`/api/v1/quote`).
`expected_surplus`	Estimate price improvement versus a public aggregator (KyberSwap), in basis points.
`build_order`	A bounded, ready-to-sign CoW order: correct per-chain settlement + orderbook, CIP-75 partner fee in appData, receiver pinned to owner.
`submit_order`	Relay a pre-signed order to the orderbook (`/api/v1/orders`). No keys held here.
`get_integrator_earnings`	Routed volume, the Ophis base fee, and the integrator's own fee on CoW-hosted chains, by appCode (`rebates.ophis.fi/earnings/:appCode`).
`get_balances`	Native + ERC-20 balances for an address on one chain.
`get_portfolio`	Native + ERC-20 balances across multiple chains.
`get_gas`	Current gas price for a chain (informational; offchain order signatures are gasless, approvals and other wallet transactions are not).
`get_token_chart`	OHLCV price history for a token.
`validate_order`	Offline preflight for an externally-built order (no network, no keys): catches wrong appCode, orderbook host, EIP-712 domain, appData hash mismatch, unpinned receiver, and expired or non-zero-fee orders.

Typical agent flow

parse_intent("swap 100 USDC for WETH on Optimism")

→ resolve_token({ chainId, symbol }) for BOTH the sell and buy symbols // canonical addresses, fails closed (anti-spoof); for a native-coin request like ETH, resolve the wrapped symbol (WETH) → get_quote({ chainId, sellToken, buyToken, kind:'sell', amount, from }) → build_order({ chainId, owner, sellToken, buyToken, sellAmount, buyAmount /* slippage-adjusted */, kind }) → (agent confirms with the user, then signs order as EIP-712 using signing) → submit_order({ chainId, order, signature, from, fullAppData })

Develop

pnpm --filter @ophis/mcp-server test         # unit tests (pure logic)

pnpm --filter @ophis/mcp-server typecheck pnpm --filter @ophis/mcp-server dev # wrangler dev (local Streamable HTTP) npx @modelcontextprotocol/inspector@latest # point at http://localhost:8787/mcp

dev / deploy / dry-run auto-build the workspace SDK first (pre* scripts), so a clean checkout works without a manual @ophis/sdk build.

Deploy

Auto-deploys on push to main via .github/workflows/mcp-deploy.yml, using the least-privilege CLOUDFLARE_WORKERS_TOKEN secret (Workers Scripts + Routes only). Manual:

pnpm --filter @ophis/mcp-server deploy        # builds the SDK, then wrangler deploy → mcp.ophis.fi

Custom domain mcp.ophis.fi is provisioned from wrangler.jsonc (routes).

After the main deployment succeeds, an organization admin creates the matching mcp-v tag. .github/workflows/mcp-registry-release.yml verifies that the live /health version matches, then publishes server.json to the official MCP Registry. See the release runbook.
