AI agents invoke fpga_config to trigger actions in Nevercheese Pcileech Memprocfs. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Writing to an FPGA modifies hardware-level configuration that can have irreversible or highly impactful effects on system behavior, firmware, and DMA operations. Since the tool spans Read and Write at the hardware/firmware level, and writing FPGA configuration can be destructive or cause system instability, the most severe applicable category is Execute (triggering external hardware operations).
From the tool's definition 'Read or write the FPGA' — the tool can both read from and write to FPGA hardware configuration, part of a DMA-based memory operations server
Documented attack patterns abuse exactly the kind of access fpga_config gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nevercheese Pcileech Memprocfs, and nothing reaches the server without passing your rules. This is the rule we recommend for fpga_config:
{
"version": "1",
"default": "deny",
"tools": {
"fpga_config": {
"limits": [
{
"counter": "fpga_config_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}fpga_config stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Read or write the FPGA. It is categorised as a Execute tool in the Nevercheese Pcileech Memprocfs MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Nevercheese Pcileech Memprocfs MCP server in PolicyLayer and add a rule for fpga_config: 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 Nevercheese Pcileech Memprocfs. Nothing to install.
fpga_config 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 fpga_config 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 fpga_config. 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.
fpga_config is provided by the Nevercheese Pcileech Memprocfs MCP server (neverdecel/nevercheese-pcileech-memprocfs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nevercheese Pcileech Memprocfs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
