AI agents invoke keeta_derive_account to trigger actions in Keeta Network MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Although the tool itself is deterministic and does not directly move funds, it generates the cryptographic material (keypair/private key) needed to authorize and execute financial transactions and asset transfers on the blockchain. Misuse by an AI agent with access to a valid seed could enable unauthorized account creation and control of funds.
From the tool's definition Derive a Keeta account (public/private keypair) from a seed and index. The tool generates cryptographic keypairs which control access to blockchain accounts. The returned address is used as account/token identifiers in all other financial tools on the server.
Attacks that exploit this kind of access
Derive a Keeta account (public/private keypair) from a seed and index. Each unique (seed, index, algorithm) combination produces a deterministic account. The returned address (keeta_...) is used in all other tools as account/token identifiers. Supported algorithms: - SECP256K1 (default) — most common, Ethereum-compatible - SECP256R1 — WebAuthn/passkey compatible - ED25519 — fast signatures Returns: { address: string, algorithm: string, index: number }. It is categorised as a Execute tool in the Keeta Network MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Keeta Network MCP Server MCP server in PolicyLayer and add a rule for keeta_derive_account: 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 Keeta Network MCP Server. Nothing to install.
keeta_derive_account is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the keeta_derive_account 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 keeta_derive_account. 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.
keeta_derive_account is provided by the Keeta Network MCP Server MCP server (schenkty/kta-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
