What is okx-mcp-skill?

A UXC connection to OKX OnchainOS MCP, a service for blockchain token, market, wallet, and decentralized-exchange data and operations.

Finding tokens, checking prices and trades, viewing balances, inspecting market data, and planning DEX quotes or swaps.

It provides help-first schema inspection and authentication guidance before using OKX's tools, including flows that can prepare swaps or other wallet actions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00078	$0.01330
Opus 5	$0.00039	$0.00665
Sonnet 5	$0.00016	$0.00266
Haiku 4.5	$0.00008	$0.00133

Measured 10d ago against content hash 210ed8cf8f41, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-10, from the pricing page.

Security

Grade A, and why

okx-mcp-skill 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

OKX MCP Skill

Use this skill to run OKX MCP operations through uxc.

Reuse the uxc skill for shared protocol discovery, output parsing, and generic auth/binding flows.

Prerequisites

uxc is installed and available in PATH.
Network access to https://web3.okx.com/api/v1/onchainos-mcp.
OKX Onchain API key is available for real calls.

Quick Trial Key

For quick read-only trial, OKX docs currently expose a shared demo key:

d573a84c-8e79-4a35-b0c6-427e9ad2478d

Example:

uxc auth credential set okx-mcp --auth-type api_key --api-key-header OK-ACCESS-KEY --secret d573a84c-8e79-4a35-b0c6-427e9ad2478d

Use your own key for regular usage, stability, and production workflows.

Core Workflow

Confirm endpoint and protocol with help-first probing:
- uxc https://web3.okx.com/api/v1/onchainos-mcp -h
Configure credential/binding for repeatable auth:
- uxc auth credential set okx-mcp --auth-type api_key --api-key-header OK-ACCESS-KEY --secret-env OKX_ACCESS_KEY
- uxc auth credential set okx-mcp --auth-type api_key --api-key-header OK-ACCESS-KEY --secret-op op://Engineering/okx/OK-ACCESS-KEY
- uxc auth binding add --id okx-mcp --host web3.okx.com --path-prefix /api/v1/onchainos-mcp --scheme https --credential okx-mcp --priority 100
Use fixed link command by default:
- command -v okx-mcp-cli
- If missing, create it: uxc link okx-mcp-cli https://web3.okx.com/api/v1/onchainos-mcp
- okx-mcp-cli -h
Inspect operation schema before execution:
- okx-mcp-cli dex-okx-market-price -h
- okx-mcp-cli dex-okx-market-token-search -h
- okx-mcp-cli dex-okx-balance-total-value -h
- okx-mcp-cli dex-okx-dex-quote -h
Prefer read operations first, then high-impact operations.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
