READ-ONLY — enumerate a Solana wallet's MarginFi lending positions. Probes the first 4 MarginfiAccount PDAs under the wallet (accountIndex 0..3) and returns one entry per existing account.

AI agents call get_marginfi_positions to retrieve information from VaultPilot MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |

wallet | string | Yes | Solana wallet to enumerate MarginFi positions for. Probes the first 4 MarginfiAccount PDAs under this wallet (accountIndex 0..3) and returns one entry per exist |
Parameters from the server's own tool schema.
Even though get_marginfi_positions 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.

READ-ONLY — enumerate a Solana wallet's MarginFi lending positions. Probes the first 4 MarginfiAccount PDAs under the wallet (accountIndex 0..3) and returns one entry per existing account. Each entry reports the supplied and borrowed balances per bank (human amount + USD value), aggregate totals, and the health factor (assets/liabilities, >1 safe, <1 liquidatable, Infinity when no debt). Bank-level pause warnings surface in the warnings field. Parallel to EVM's get_compound_positions / get_morpho_positions. Returns an empty array when the wallet has no MarginfiAccount. It is categorised as a Read tool in the VaultPilot MCP MCP Server, which means it retrieves data without modifying state.
get_marginfi_positions accepts 1 parameter: wallet. Required: wallet. The full parameter table on this page comes from the server's own tool schema.
Register the VaultPilot MCP server in PolicyLayer and add a rule for get_marginfi_positions: 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 VaultPilot MCP. Nothing to install.
get_marginfi_positions 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 get_marginfi_positions 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 get_marginfi_positions. 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.
get_marginfi_positions is provided by the VaultPilot MCP server (vaultpilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
