get_sbu
AI agents call get_sbu to retrieve information from Mofstructure without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to query and retrieve SBU (Secondary Building Unit) data from Metal-Organic Framework structures, consistent with the server's purpose of 'deconstructing and analyzing' crystal structures. No description was provided, but the naming pattern and context of sibling read-only analysis tools (analyze, get, identify) suggest this is a data retrieval operation with no side effects.
From the tool's definition Tool name 'get_sbu' suggests retrieval of Secondary Building Unit information from MOF structures. Sibling tools like 'get_ligands', 'analyze_cof_stacking', and 'remove_guest' indicate this server performs structural analysis and characterization without…
Attacks that exploit this kind of access
get_sbu. It is categorised as a Read tool in the Mofstructure MCP Server, which means it retrieves data without modifying state.
Register the Mofstructure MCP server in PolicyLayer and add a rule for get_sbu: 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 Mofstructure. Nothing to install.
get_sbu 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_sbu 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_sbu. 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_sbu is provided by the Mofstructure MCP server (lichman0405/mofstructure-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
