Part of the Pylon Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use pylon_create_tag to create or modify resources in Pylon Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call pylon_create_tag repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Pylon Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Create a new tag for categorizing issues and contacts. Use this to add new categories that help organize and filter your support tickets effectively.. It is categorised as a Write tool in the Pylon Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for pylon_create_tag. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Pylon Server MCP server.
pylon_create_tag is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the pylon_create_tag 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 pylon_create_tag. 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.
pylon_create_tag is provided by the Pylon Server MCP server (marcinwyszynski/pylon-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
