List all accounting projects accessible to the user, optionally filtered by organization. Results are paginated — if a continuationToken is returned, pass it in the next call to retrieve more.
AI agents call list_projects to retrieve information from TreeBeam MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs data retrieval only (list/query), returning paginated results of projects the user is already authorized to access. There are no side effects, no data modification, no code execution, and no financial movements. The presence of destructive and write operations on the sibling tools (delete_account, create_adjustment) does not change the nature of this specific tool, which is purely informational.
From the tool's definition Tool description states 'List all accounting projects accessible to the user' — a retrieval operation with no modification or destructive capability. Pagination via continuationToken is a common read-only pattern.
Attacks that exploit this kind of access
List all accounting projects accessible to the user, optionally filtered by organization. Results are paginated — if a continuationToken is returned, pass it in the next call to retrieve more. It is categorised as a Read tool in the TreeBeam MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TreeBeam MCP Server MCP server in PolicyLayer and add a rule for list_projects: 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 TreeBeam MCP Server. Nothing to install.
list_projects 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_projects 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_projects. 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_projects is provided by the TreeBeam MCP Server MCP server (treebeam-code/tb-mcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
