What is solana-setup?

A setup and maintenance skill for the solana-onchain-mcp command-line program, which connects an agent to Solana blockchain data or actions through MCP.

Use it to check, install, update, or verify the solana-onchain-mcp program.

It removes the need to manually check whether the program is installed, which version is present, or whether an update is available. It also verifies the installation after setup.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add widnyana/eyay-toolkits --skill solana-setup

Clone the repo

git clone --depth 1 https://github.com/widnyana/eyay-toolkits

Made for: Claude Code.

Or install solana-onchain, the plugin that ships this one along with the rest of its 8 skills.

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	$0.00069	$0.00581
Opus 5.5	$0.00028	$0.00232
Sonnet 5.5	$0.00014	$0.00116
Haiku 4.5	$0.00007	$0.00058

Security

Grade C, and why

solana-setup scanned grade C with 2 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 1mo ago.

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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

- **Prebuilt binary (recommended)**: `curl -fsSL https://raw.githubusercontent.com/widnyana/solana-onchain-mcp/refs/heads/main/install.sh | bash`

What it actually says

Install, update, or verify the solana-onchain-mcp binary.

Review: $ARGUMENTS

Instructions

status (default)

Check binary exists: command -v solana-onchain-mcp
If not found — report "solana-onchain-mcp is not installed" and skip to install section.
If found — get installed version: solana-onchain-mcp --version

Get latest version:

curl -sf --connect-timeout 5 https://crates.io/api/v1/crates/solana-onchain-mcp | python3 -c "import sys,json; print(json.load(sys.stdin)['crate']['max_version'])" 2>/dev/null

If network fails: report installed version only, warn that latest check failed.

Compare versions and report:
- Same: "v{version} is up to date."
- Different: "Installed v{installed}, latest v{latest}. Run /solana-setup update."

install

Confirm with user which method:
- Prebuilt binary (recommended): curl -fsSL https://raw.githubusercontent.com/widnyana/solana-onchain-mcp/refs/heads/main/install.sh | bash
- Cargo: cargo install solana-onchain-mcp
Execute the chosen command.
Verify: command -v solana-onchain-mcp && solana-onchain-mcp --version
Report success with binary location and version.

update

Check installed version: solana-onchain-mcp --version
Check latest version (same as status step 4).
If already latest: report "Already up to date."
If outdated: confirm with user, then:
- Prebuilt: re-run install.sh (always fetches latest)
- Cargo: cargo install solana-onchain-mcp --force
Verify new version after update.

Error handling

curl fails: suggest checking internet connection, offer to retry
cargo not found: suggest prebuilt method or installing Rust
Permission denied: suggest checking install directory permissions
Version check fails: still allow install, just can't compare versions

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.

solana-setup is a skill published in the GitHub repository widnyana/eyay-toolkits (8 stars, last pushed 3d ago), licensed MIT. It adds 69 tokens to every session and 581 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
