Return the full skill inventory (name + one-line description). Use once per session to learn what
AI agents call list_all_skills to retrieve information from SkillStream MCP 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 data (skill names and descriptions) without creating, modifying, deleting, or executing anything. It is a pure read operation with minimal security risk—the worst outcome is information disclosure about available skills.
From the tool's definition Tool name 'list_all_skills' and description 'Return the full skill inventory' indicate a retrieval operation with no modification or side effects. The description explicitly positions it as an inventory query ('Use once per session to learn what').
Attacks that exploit this kind of access
Return the full skill inventory (name + one-line description). Use once per session to learn what. It is categorised as a Read tool in the SkillStream MCP MCP Server, which means it retrieves data without modifying state.
Register the SkillStream MCP server in PolicyLayer and add a rule for list_all_skills: 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 SkillStream MCP. Nothing to install.
list_all_skills 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_all_skills 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_all_skills. 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_all_skills is provided by the SkillStream MCP server (pr-botsai/skillstream-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
