Read a Nastran BDF input file and return model summary.
AI agents call read_bdf to retrieve information from pyNastran MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward read operation on a Nastran BDF (Bulk Data Format) file, returning a summary of the model structure. It retrieves data without creating, modifying, deleting, or executing operations. The action is purely informational with no irreversible consequences or external side effects. This aligns directly with the Read category definition.
From the tool's definition Tool name 'read_bdf' and description 'Read a Nastran BDF input file and return model summary' explicitly indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Read a Nastran BDF input file and return model summary. It is categorised as a Read tool in the pyNastran MCP Server MCP Server, which means it retrieves data without modifying state.
Register the pyNastran MCP Server MCP server in PolicyLayer and add a rule for read_bdf: 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 pyNastran MCP Server. Nothing to install.
read_bdf 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 read_bdf 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 read_bdf. 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.
read_bdf is provided by the pyNastran MCP Server MCP server (shaoqigit/pynastran-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
