Load a named gallery template as a base64-encoded RVF container. Use when native Read is wrong because RVF containers are packed inside the WASM gallery store and are not accessible as plain filesystem files.
AI agents call wasm_gallery_load_rvf to retrieve information from Claude Flow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the specialized nature of loading WASM containers and RVF format encoding, the tool performs no side effects—it only retrieves and returns existing template data from a gallery store. The base64 encoding is output formatting, not execution. No data is modified, deleted, or executed.
From the tool's definition Tool description states 'Load a named gallery template as a base64-encoded RVF container' — this is a retrieval operation.
Attacks that exploit this kind of access
Load a named gallery template as a base64-encoded RVF container. Use when native Read is wrong because RVF containers are packed inside the WASM gallery store and are not accessible as plain filesystem files. It is categorised as a Read tool in the Claude Flow MCP Server, which means it retrieves data without modifying state.
Register the Claude Flow MCP server in PolicyLayer and add a rule for wasm_gallery_load_rvf: 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 Claude Flow. Nothing to install.
wasm_gallery_load_rvf 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 wasm_gallery_load_rvf 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 wasm_gallery_load_rvf. 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.
wasm_gallery_load_rvf is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
