@Smithery

Cross-chain swaps, bridging, and DeFi yield discovery via the LI.FI aggregator. Provides MCP tools for quotes, routes, token and chain metadata, transaction status, ERC20 allowances, and yield vaults across 58 chains, 27+ bridges, and 31+ DEXes. Read-only — returns unsigned transaction requests for the agent's wallet to sign and broadcast. An optional LI.FI API key (Bearer or X-LiFi-Api-Key header) unlocks higher rate limits.

Risk Summary

Needs Approval

Dep Visibility plus Excessive Permissions raises enough risk that this tool should not be auto-trusted.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

Recommended action: Keep this tool behind manual approval and avoid unattended runs until the risky capabilities are narrowed or removed.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (77)

  • HighAS-002

    ⚠️Excessive Permissions ×17

    tool declares network permission

    get-allowanceget-chain-by-idget-chain-by-nameget-chainsget-earn-chainsget-earn-protocolsget-gas-pricesget-native-token-balanceget-token-balanceget-token-balancestest-api-key

    tool declares exec permission

    get-allowanceget-gas-pricesget-quote-with-callsget-routesget-step-transactionget-tokens

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • HighAS-010

    🔑Insecure Secret Handling ×12

    input parameter "tokenAddress" appears to accept a secret or credential

    input parameter "toToken" appears to accept a secret or credential

    get-connectionsget-quoteget-quote-with-calls

    input parameter "fromToken" appears to accept a secret or credential

    get-connectionsget-quoteget-quote-with-calls

    input parameter "fromTokenAddress" appears to accept a secret or credential

    input parameter "toTokenAddress" appears to accept a secret or credential

    get-routes

    input parameter "token" appears to accept a secret or credential

    get-token

    input parameter "tokenAddresses" appears to accept a secret or credential

    get-token-balances

    Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.

  • MediumAS-002

    ⚠️Excessive Permissions

    get-earn-vaults:tool declares fs permission

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×18

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  • LowAS-002

    ⚠️Excessive Permissions ×4

    tool declares http permission

    get-earn-portfolioget-earn-vaultsget-tools

    input schema exposes 12 properties (threshold: 10)

    get-quote

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×25

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

Scan this tool yourself

Reproduce this audit locally, integrate into CI, or let your agent audit its own tools.

Install once, then scan any MCP server:

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y li-fi-lifi-mcp"
