get_next_suggestion
AI agents call get_next_suggestion to retrieve information from Vivado without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on naming convention ('get_*'), this tool appears to retrieve or query suggestions—likely related to FPGA development diagnostics or diagnostics from sibling tools like 'get_critical_warnings' and 'check_bitstream_readiness'. Without a description, confidence is moderate, but the pattern suggests a Read operation that returns information without modifying state.
From the tool's definition Tool name 'get_next_suggestion' indicates a retrieval operation with no mutating side effects. The description is empty, limiting direct evidence.

PolicyLayer is an MCP gateway — it sits between your AI agents and Vivado, and nothing reaches the server without passing your rules. This is the rule we recommend for get_next_suggestion:
{
"version": "1",
"default": "deny",
"tools": {
"get_next_suggestion": {}
}
}get_next_suggestion is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_next_suggestion. It is categorised as a Read tool in the Vivado MCP Server, which means it retrieves data without modifying state.
Register the Vivado MCP server in PolicyLayer and add a rule for get_next_suggestion: 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 Vivado. Nothing to install.
get_next_suggestion is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_next_suggestion 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 get_next_suggestion. 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.
get_next_suggestion is provided by the Vivado MCP server (mapleleavessssssss-wq/vivado-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vivado, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
