Part of the 21e14 MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke compose_xcp420_fairminter to trigger processes or run actions in 21e14. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
compose_xcp420_fairminter can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Compose a XCP-420 compliant fair launch. XCP-420 is a community standard that enforces fixed parameters: 10M supply, 4.2M soft cap, 0.1 XCP per mint, 1000 tokens per mint, 1000 block duration, no premine, no commission, burn payment, locked supply. Only the asset name, start block, and description are configurable.. It is categorised as a Execute tool in the 21e14 MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for compose_xcp420_fairminter. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the 21e14 MCP server.
compose_xcp420_fairminter 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 compose_xcp420_fairminter rule in your Intercept 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 Intercept policy for compose_xcp420_fairminter. 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.
compose_xcp420_fairminter is provided by the 21e14 MCP server (@21e14/mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
