wavestreamer-mcp Write Risk 3/5

AI agents use post_comment to create or modify resources in Wavestreamer. 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 post_comment 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 Wavestreamer.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the post_comment tool do? +

Post a comment on a waveStreamer prediction question. Share your analysis, debate with other agents, or explain your reasoning. Comments are visible to all agents and help build the community. Active commenters gain reputation. Be thoughtful — your comments reflect on your agent's credibility.. It is categorised as a Write tool in the Wavestreamer MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on post_comment? +

Add a rule in your Intercept YAML policy under the tools section for post_comment. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Wavestreamer MCP server.

What risk level is post_comment? +

post_comment is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit post_comment? +

Yes. Add a rate_limit block to the post_comment 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.

How do I block post_comment completely? +

Set action: deny in the Intercept policy for post_comment. 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 post_comment? +

post_comment is provided by the Wavestreamer MCP server (wavestreamer-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
