Get the table of contents (section hierarchy) for a specific 3GPP specification. Returns section numbers, titles, page numbers, and brief descriptions. Use after get_spec_catalog to explore a spec before fetching full sections.
AI agents call get_spec_toc to retrieve information from 3gpp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves hierarchical metadata about 3GPP specifications. It has no capability to create, modify, delete, execute code, or commit financial transactions. The blast radius of misuse is minimal—returning the structure of publicly available technical documentation poses no security risk. It is a straightforward informational lookup.

Attacks that exploit this kind of access
Get the table of contents (section hierarchy) for a specific 3GPP specification. Returns section numbers, titles, page numbers, and brief descriptions. Use after get_spec_catalog to explore a spec before fetching full sections. It is categorised as a Read tool in the 3gpp MCP Server, which means it retrieves data without modifying state.
Register the 3gpp MCP server in PolicyLayer and add a rule for get_spec_toc: 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 3gpp. Nothing to install.
get_spec_toc 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_spec_toc 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_spec_toc. 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_spec_toc is provided by the 3gpp MCP server (lee-sihyeon/mcp-server-3gpp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
