List models inside a Speckle project.
AI agents call list_models to retrieve information from Bim Change Engine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of existing models within a project—a pure data retrieval operation with no side effects, resource consumption, or risk of unintended consequences. It belongs in the Read category with low severity.
From the tool's definition Tool name 'list_models' and description 'List models inside a Speckle project' indicate a retrieval/query operation with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
List models inside a Speckle project. It is categorised as a Read tool in the Bim Change Engine MCP Server, which means it retrieves data without modifying state.
Register the Bim Change Engine MCP server in PolicyLayer and add a rule for list_models: 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 Bim Change Engine. Nothing to install.
list_models 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 list_models 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 list_models. 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.
list_models is provided by the Bim Change Engine MCP server (rishibajaj-prodman/bim-change-engine). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
