WHAT IT DOES

What start_interest_oracle does on Indigo Protocol MCP

AI agents invoke start_interest_oracle to trigger actions in Indigo Protocol MCP. 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.

Parameter	Type	Required	Description
`owner`	string	—	Oracle operator pub key hash (hex)
`address`	string	—	Admin Cardano bech32 address
`biasTime`	string	—	Oracle bias time in milliseconds as bigint string
`initialInterestRate`	string	—	Initial interest rate as bigint string
`initialUnitaryInterest`	string	—	Initial unitary interest as bigint string
`initialLastInterestUpdate`	string	—	Initial last interest update timestamp (milliseconds) as bigint string

Parameters from the server's own tool schema.

RISK

Why start_interest_oracle is rated High

This tool triggers a protocol-level administrative operation that initializes a critical oracle component. While it returns an unsigned transaction (requiring further confirmation), the act of initializing a new oracle is an irreversible operational change affecting the Indigo Protocol's interest rate mechanism.

From the tool's definition Initialize a new interest oracle (one-time admin setup)... callable by protocol administrators.

RECOMMENDED RULE

The rule that runs start_interest_oracle safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Indigo Protocol MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For start_interest_oracle, this is the rule to start with:

start_interest_oracle Rate-limited

start_interest_oracle stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about start_interest_oracle

What does the start_interest_oracle tool do? +

Initialize a new interest oracle (one-time admin setup). Returns an unsigned transaction (CBOR hex) and the minted oracle asset class. Only callable by protocol administrators. It is categorised as a Execute tool in the Indigo Protocol MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

What parameters does start_interest_oracle accept? +

start_interest_oracle accepts 6 parameters: owner, address, biasTime, initialInterestRate, initialUnitaryInterest, initialLastInterestUpdate. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on start_interest_oracle? +

Register the Indigo Protocol MCP server in PolicyLayer and add a rule for start_interest_oracle: 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 Indigo Protocol MCP. Nothing to install.

What risk level is start_interest_oracle? +

start_interest_oracle is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start_interest_oracle? +

Yes. Add a rate_limit block to the start_interest_oracle 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.

How do I block start_interest_oracle completely? +

Set action: deny in the PolicyLayer policy for start_interest_oracle. 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.

What MCP server provides start_interest_oracle? +

start_interest_oracle is provided by the Indigo Protocol MCP server (indigoprotocol/indigo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
