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.

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 | $0.00076 | $0.00929 |
| Opus 5 | $0.00038 | $0.00464 |
| Sonnet 5 | $0.00015 | $0.00186 |
| Haiku 4.5 | $0.00008 | $0.00093 |
Grade A, and why
phantom-wallet-mcp 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 8d 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.
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.
How it starts
The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Phantom Wallet MCP
Use the phantom MCP server to interact with the user's Phantom wallet directly — no SDK integration code needed.
Setup
Add the Phantom MCP server to your MCP configuration:
{
"mcpServers": {
"phantom": {
"command": "npx",
"args": ["-y", "@phantom/mcp-server"],
"env": {
"PHANTOM_APP_ID": "<your-app-id>"
}
}
}
}
Get your PHANTOM_APP_ID from Phantom Portal. On first use, the server opens a browser for OAuth authentication via Google or Apple login.

Examples
Get wallet addresses
Retrieve the user's wallet addresses across all supported chains:
Use the phantom MCP's get_wallet_addresses tool to list the user's addresses.
Returns addresses for each connected chain (Solana, Ethereum, Bitcoin, Sui).
Transfer SOL
Send SOL to a recipient address:
Use the phantom MCP's transfer_tokens tool:
- token: "SOL"
- recipientAddress: "<recipient>"
- amount: "0.1"
- network: "solana:mainnet"
The MCP handles transaction building, signing, and submission.
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.
