Analyze the distribution of trial phases for given search criteria. This tool analyzes the distribution of clinical trial phases (e.g., Phase 1, Phase 2, Phase 3) for a given set of search criteria. Input: - conditions: A list of medical conditions to filter the analysis. - interventions: A list ...

AI agents call analyze_trial_phases to retrieve information from Clinical Trials Data Server 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 analyze_trial_phases 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.

Analyze the distribution of trial phases for given search criteria. This tool analyzes the distribution of clinical trial phases (e.g., Phase 1, Phase 2, Phase 3) for a given set of search criteria. Input: - conditions: A list of medical conditions to filter the analysis. - interventions: A list of interventions to filter the analysis. - sponsors: A list of sponsors to filter the analysis. - max_studies: The maximum number of studies to include in the analysis. Defaults to 1000.. It is categorised as a Read tool in the Clinical Trials Data Server MCP Server, which means it retrieves data without modifying state.
Register the Clinical Trials Data Server MCP server in PolicyLayer and add a rule for analyze_trial_phases: 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 Clinical Trials Data Server. Nothing to install.
analyze_trial_phases 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 analyze_trial_phases 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 analyze_trial_phases. 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.
analyze_trial_phases is provided by the Clinical Trials Data Server MCP server (plainyogurt21/clintrials-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
