Load the full body of a skill by name. Equivalent to reading the skill://<name> resource. Use after search_skills or list_all_skills tells you which one you want.
AI agents call activate_skill 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.
The tool retrieves and returns skill content without any side effects. It is explicitly described as equivalent to reading a resource, making it a straightforward Read operation. Misuse potential is minimal as it only fetches data.
From the tool's definition "Load the full body of a skill by name. Equivalent to reading the skill://<name> resource."
Attacks that exploit this kind of access
Load the full body of a skill by name. Equivalent to reading the skill://<name> resource. Use after search_skills or list_all_skills tells you which one you want. 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 activate_skill: 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.
activate_skill 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 activate_skill 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 activate_skill. 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.
activate_skill 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.
