AI agents call show_appointments_basic to retrieve information from Eka EMR 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 show_appointments_basic 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.

Retrieve a list of appointments with basic data containing entity IDs only, without patient, doctor, or clinic details. When to Use This Tool Use this tool only when raw appointment records are required. Use show_appointments_enriched otherwise. This tool is intended for internal workflows, debugging, or follow-up calls where entity details will be resolved separately. Trigger Keywords / Phrases raw appointments, appointment ids, basic appointment list, internal lookup, debug appointments, lightweight appointment data Returns: Basic appointments with entity IDs only If no appointments match the filters, returns an empty appointments array. Timestamps are Unix epoch (UTC-based). IMPORTANT: Always use Python/bash to convert timestamps - never do mental math. Use the below code. python3 -c "import datetime; print(datetime.datetime.fromtimestamp(TIMESTAMP, tz=datetime.timezone(datetime.timedelta(hours=5, minutes=30))).strftime('%I:%M %p IST'))". It is categorised as a Read tool in the Eka EMR MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for show_appointments_basic. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Eka EMR MCP server.
show_appointments_basic 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 show_appointments_basic rule in your Intercept 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 Intercept policy for show_appointments_basic. 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.
show_appointments_basic is provided by the Eka EMR MCP server (eka-care/emr). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
