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 | $0.00041 | $0.00479 |
| Opus 5 | $0.00020 | $0.00239 |
| Sonnet 5 | $0.00008 | $0.00096 |
| Haiku 4.5 | $0.00004 | $0.00048 |
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 4d 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.
This is a copy
100% identical to phantom-wallet-mcp — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Phantom Wallet MCP
Use the phantom MCP server to interact with the user's Phantom wallet directly.
Available Tools
| Tool | Description |
|---|---|
get_wallet_addresses |
Get blockchain addresses (Solana, Ethereum, Bitcoin, Sui) for the connected wallet |
sign_transaction |
Sign a transaction (base64url for Solana, RLP hex for Ethereum) |
transfer_tokens |
Transfer SOL or SPL tokens on Solana — builds, signs, and sends the transaction |
buy_token |
Fetch Solana swap quotes from Phantom API; optionally sign and send |
sign_message |
Sign a UTF-8 message with automatic chain-specific routing |
Setup
The phantom MCP server requires a PHANTOM_APP_ID environment variable from Phantom Portal. On first use, it opens a browser for OAuth authentication via Google or Apple login.
Supported Networks
| Chain | Networks |
|---|---|
| Solana | mainnet, devnet, testnet |
| Ethereum | Mainnet, Sepolia, Polygon, Base, Arbitrum |
| Bitcoin | Mainnet |
| Sui | Mainnet, Testnet |
Networks use CAIP-2 format (e.g., solana:mainnet, eip155:1).
Examples
Get wallet addresses
Ask the phantom MCP to retrieve the user's wallet addresses, then use them for transactions.
Transfer SOL
Use transfer_tokens to send SOL to a recipient address. The MCP handles transaction building, signing, and submission.
Sign a message
Use sign_message for wallet verification or authentication flows. The MCP routes to the correct chain based on the network parameter.
Important Notes
- Sessions persist locally in
~/.phantom-mcp/session.json - This is preview software — use a separate wallet with minimal funds for testing
- The MCP server runs via stdio transport (launched by
npx -y @phantom/mcp-server)
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.
