Derive Solana program-derived addresses offline: findProgramAddress (canonical bump search) for any program and typed seeds (utf8, base58 pubkey, hex, u8/u16/u32/u64 little- or big-endian), or the associated token account (ATA) of an owner + mint for SPL Token or Token-2022.

What sol_pda does on ScorpTech x402 API
AI agents call sol_pda to retrieve information from ScorpTech x402 API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
bump | integer | — | custom: use this bump (createProgramAddress) instead of searching |
mint | string | — | ata: token mint |
owner | string | — | ata: wallet that owns the token account |
seeds | array | — | custom: seeds as "utf8:vault", "pubkey:<base58>", "hex:0a0b", "u8:1", "u64:42", "u32be:7" (no prefix: a 32-byte base58 string is a pubkey, else utf8); JSON arra |
preset | string | — | ata = associated token account of owner + mint; custom = programId + seeds |
programId | string | — | custom: program id (base58) |
tokenProgram | string | — | ata: SPL Token (default) or Token-2022 |
Parameters from the server's own tool schema.
Why sol_pda is rated Low
Even though sol_pda only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs sol_pda safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sol_pda, this is the rule to start with:
sol_pda is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every sol_pda call is checked against it from then on.
Questions about sol_pda
Derive Solana program-derived addresses offline: findProgramAddress (canonical bump search) for any program and typed seeds (utf8, base58 pubkey, hex, u8/u16/u32/u64 little- or big-endian), or the associated token account (ATA) of an owner + mint for SPL Token or Token-2022. Same algorithm as @solana/web3.js (sha256 + ed25519 off-curve check). Useful to locate token accounts, Anchor PDAs and vaults without an RPC. Price: $0.002 USDC per successful call (x402, Solana). Same tool over HTTPS: GET https://scorptech.it.com/api/x402/v1/sol-pda. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.
sol_pda accepts 7 parameters: bump, mint, owner, seeds, preset, programId, tokenProgram. The full parameter table on this page comes from the server's own tool schema.
Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for sol_pda: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ScorpTech x402 API. Nothing to install.
sol_pda is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the sol_pda rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for sol_pda. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
sol_pda is provided by the ScorpTech x402 API MCP server (https://scorptech.it.com/api/x402/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
