Reload a clean open buffer from disk without discarding unsaved changes.
AI agents call reload_buffer to retrieve information from Vigentic MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads the file from disk and refreshes the buffer state. It does not modify, delete, or execute anything. However, the description is slightly ambiguous ('without discarding unsaved changes' could mean it merges or preserves in-memory state), which lowers confidence slightly. The primary action is reading/refreshing from disk.

Attacks that exploit this kind of access
Reload a clean open buffer from disk without discarding unsaved changes. It is categorised as a Read tool in the Vigentic MCP MCP Server, which means it retrieves data without modifying state.
Register the Vigentic MCP server in PolicyLayer and add a rule for reload_buffer: 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 Vigentic MCP. Nothing to install.
reload_buffer 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 reload_buffer 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 reload_buffer. 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.
reload_buffer is provided by the Vigentic MCP server (munozu/vigentic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
