AI agents call get_accident_cases to retrieve information from 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_accident_cases only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Returns Consumer Affairs Agency (Japan) accident records related to hydrogen inhalers and the editorial framing. Use when the user asks about real-world safety incidents.. It is categorised as a Read tool in the 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) MCP Server, which means it retrieves data without modifying state.
Register the 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) MCP server in PolicyLayer and add a rule for get_accident_cases: 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 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers). Nothing to install.
get_accident_cases 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 get_accident_cases 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 get_accident_cases. 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.
get_accident_cases is provided by the 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) MCP server (@h2-papers/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
