fetch_result
AI agents call fetch_result to retrieve information from FTIR Fun MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Fetching results is a read operation with no side effects. The server performs spectrum analysis and returns candidates; fetch_result appears to retrieve those results. No creation, modification, or deletion of data is implied. Severity is low because the tool retrieves analysis metadata/results with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'fetch_result' suggests retrieving previously computed results. Given the server context (FTIR spectrum analysis returning 'spectral-library candidates'), this tool likely retrieves analysis results without modifying data.
Attacks that exploit this kind of access
fetch_result. It is categorised as a Read tool in the FTIR Fun MCP Server MCP Server, which means it retrieves data without modifying state.
Register the FTIR Fun MCP Server MCP server in PolicyLayer and add a rule for fetch_result: 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 FTIR Fun MCP Server. Nothing to install.
fetch_result 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 fetch_result 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 fetch_result. 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.
fetch_result is provided by the FTIR Fun MCP Server MCP server (jxbaoxiaodong/ftirfun-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
