List tools from a provider with full schemas for agent configuration. Returns tool names, parameters (with form type, required, defaults).
AI agents call list_tools to retrieve information from Pulse Workflow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns information about available tools and their schemas. It performs a query/fetch operation with no ability to modify, delete, or execute workflows. It only exposes metadata about what tools exist, making it a Read category tool with low severity since the worst outcome is information disclosure about tool availability.
From the tool's definition Tool name is 'list_tools' and description states it 'List tools from a provider with full schemas' — a retrieval operation with no modifications or side effects.
Attacks that exploit this kind of access
List tools from a provider with full schemas for agent configuration. Returns tool names, parameters (with form type, required, defaults). It is categorised as a Read tool in the Pulse Workflow MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Pulse Workflow MCP Server MCP server in PolicyLayer and add a rule for list_tools: 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 Pulse Workflow MCP Server. Nothing to install.
list_tools 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_tools 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_tools. 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_tools is provided by the Pulse Workflow MCP Server MCP server (pulse-intelligence/pulse-workflow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
