goldrush-mcp-skill

goldrush-mcp-skill is a skill for Codex from holon-run/uxc. It costs 47 tokens per session (1,241 once invoked), scanned A, original, MIT.

A connection to GoldRush, a service for querying blockchain data across multiple networks. It runs GoldRush's MCP tool server and uses an API key.

In plain words
What is it for?
Use it to check wallet balances and transfers, review portfolio history, inspect NFT ownership and token approvals, get prices, and read chain metadata.
Why use it?
It saves an agent from integrating separate requests for common multichain wallet and token information. The first use may need to download the server package.

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.

Security

Grade A, and why

goldrush-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.

GoldRush MCP Skill

Use this skill to run GoldRush MCP operations through uxc using a fixed stdio endpoint.

Reuse the uxc skill for generic protocol discovery, output parsing, and auth/error handling rules.

Prerequisites

  • uxc is installed and available in PATH.
  • npx is available in PATH (Node.js installed).
  • Network access for first-time @covalenthq/goldrush-mcp-server package fetch.
  • A GoldRush API key is available.

Core Workflow

Endpoint candidate inputs before finalizing:

  • Raw package form from docs: npx @covalenthq/goldrush-mcp-server@latest
  • Reliable non-interactive form: npx -y @covalenthq/goldrush-mcp-server@latest
  • This skill defaults to:
    • npx -y @covalenthq/goldrush-mcp-server@latest
  1. Verify protocol/path from official source and probe:
    • Official source: https://goldrush.dev/docs/goldrush-mcp-server
    • probe candidate endpoint with:
      • uxc --inject-env GOLDRUSH_API_KEY=$GOLDRUSH_API_KEY "npx -y @covalenthq/goldrush-mcp-server@latest" -h
    • cold start can take longer on first run because npx may need to download the package
  2. Configure credential for repeatable auth:
    • uxc auth credential set goldrush-mcp --auth-type bearer --secret-env GOLDRUSH_API_KEY
    • uxc auth credential set goldrush-mcp --auth-type bearer --secret-op op://Engineering/goldrush/api-key
  3. Use fixed link command by default:
    • command -v goldrush-mcp-cli
    • If missing, create it:
      • uxc link goldrush-mcp-cli "npx -y @covalenthq/goldrush-mcp-server@latest" --credential goldrush-mcp --inject-env GOLDRUSH_API_KEY={{secret}}
    • goldrush-mcp-cli -h
  4. Inspect operation schema before execution:
    • goldrush-mcp-cli getAllChains -h
    • goldrush-mcp-cli multichain_balances -h
    • goldrush-mcp-cli transactions_for_address -h
    • goldrush-mcp-cli historical_portfolio_value -h
  5. Prefer read-only discovery first, then expand into broader wallet-history or NFT scans.

Capability Map

  • Cross-chain overview:
    • getAllChains
    • multichain_address_activity
    • multichain_balances
    • multichain_transactions
  • Wallet balances and portfolio:

    • historical_token_balances
    • native_token_balance

    • nft_check_ownership
    • token_approvals

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.
