Return all WASM gallery template categories with per-category template counts. Use when native Bash/ls is wrong because gallery category metadata is indexed inside the WASM runtime, not on the filesystem.
AI agents call wasm_gallery_categories 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.
This tool queries and retrieves indexed metadata about WASM gallery categories—a read-only operation. It has no side effects, does not modify or delete data, and does not execute arbitrary code or trigger external operations. The scope is limited to returning pre-computed category metadata, making it a straightforward Read operation with low blast radius.
From the tool's definition The tool description explicitly states it 'Return[s] all WASM gallery template categories' and retrieves metadata counts.
Attacks that exploit this kind of access
Return all WASM gallery template categories with per-category template counts. Use when native Bash/ls is wrong because gallery category metadata is indexed inside the WASM runtime, not on the filesystem. 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_categories: 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_categories 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_categories 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_categories. 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_categories 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.
