Image + text reasoning via Bittensor subnet 24 (Omega Multimodal). Cost: $0.02 per call.
AI agents use bittensor_multimodal to commit financial operations through Swarmrails MCP — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Every call to this tool incurs a monetary charge ($0.02 per call) on a pay-as-you-go basis using USDC. While the per-call cost is small, an AI agent could invoke this tool many times, accumulating significant charges. The financial commitment on each call places this squarely in the Financial category, which takes precedence over the Execute nature of the underlying operation.
From the tool's definition Cost: $0.02 per call — each invocation commits a financial obligation via USDC pay-as-you-go model

Image + text reasoning via Bittensor subnet 24 (Omega Multimodal). Cost: $0.02 per call. It is categorised as a Financial tool in the Swarmrails MCP MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the Swarmrails MCP server in PolicyLayer and add a rule for bittensor_multimodal: 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 Swarmrails MCP. Nothing to install.
bittensor_multimodal is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the bittensor_multimodal 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 bittensor_multimodal. 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.
bittensor_multimodal is provided by the Swarmrails MCP server (wizerai1111/swarmrails-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
