get_history

// WHEN AGENTS USE THIS TOOL

AI agents call get_history to retrieve information from Mcp Observatory 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_history 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.

// RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access get_history gives an agent. Each links to the full case and the policy that stops it:

• Prompt Injection via Tool Results

• Credential leak via error messages
