Part of the Eka EMR MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use add_patient to create or modify resources in Eka EMR. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call add_patient repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Eka EMR.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Creates a new patient profile and returns a unique patient identifier. - If user hasn't provided any of DOB, gender or name, always ASK them before calling this tool. Do not assume anything for mandatory fields. Recommended Usage: Use when registering a new patient profile with basic demographic information. Do not use to update existing patients or modify partial profile data. Trigger Keywords: create patient, add patient profile, register new patient, new patient registration, create patient record What to Return: Returns a JSON object with: - success: boolean indicating whether patient creation succeeded - data: an object containing the created patient profile, including the unique patient ID (oid). It is categorised as a Write tool in the Eka EMR MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for add_patient. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Eka EMR MCP server.
add_patient is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the add_patient 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 add_patient. 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.
add_patient 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.
