[ts-morph] List exports that have no references outside their declaring file across the project. Read-only. When to use - Hunting for dead code candidates after a refactor or migration. - Auditing a module
AI agents call find_unused_exports_by_tsmorph to retrieve information from MCP ts-morph Refactoring Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static analysis to identify unused exports by searching for references across the project. It retrieves information about code structure and usage patterns without creating, modifying, deleting, or executing any code. The read-only designation confirms no side effects occur. Low severity because misuse causes only informational inaccuracy, not code damage or unintended operations.
From the tool's definition "List exports that have no references outside their declaring file across the project. Read-only." - explicitly marked as read-only; performs analysis and reporting without modifying code.
Documented attack patterns abuse exactly the kind of access find_unused_exports_by_tsmorph gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP ts-morph Refactoring Tools, and nothing reaches the server without passing your rules. This is the rule we recommend for find_unused_exports_by_tsmorph:
{
"version": "1",
"default": "deny",
"tools": {
"find_unused_exports_by_tsmorph": {}
}
}find_unused_exports_by_tsmorph is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

[ts-morph] List exports that have no references outside their declaring file across the project. Read-only. When to use - Hunting for dead code candidates after a refactor or migration. - Auditing a module. It is categorised as a Read tool in the MCP ts-morph Refactoring Tools MCP Server, which means it retrieves data without modifying state.
Register the MCP ts-morph Refactoring Tools MCP server in PolicyLayer and add a rule for find_unused_exports_by_tsmorph: 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 MCP ts-morph Refactoring Tools. Nothing to install.
find_unused_exports_by_tsmorph 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 find_unused_exports_by_tsmorph 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 find_unused_exports_by_tsmorph. 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.
find_unused_exports_by_tsmorph is provided by the MCP ts-morph Refactoring Tools MCP server (sirosuzume/mcp-ts-morph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP ts-morph Refactoring Tools, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
