Part of the Eka EMR MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use update_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 update_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.

Updates an existing patient profile with new or corrected information. Recommended Usage: Use when modifying patient details such as name, date of birth, gender, mobile, email, or other demographic/medical fields. Do not use for creating new patient profiles or fetching existing patient data. Trigger Keywords: update patient, edit patient profile, modify patient details, change patient information, correct patient record Returns: Success message confirming profile update. 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 update_patient. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Eka EMR MCP server.
update_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 update_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 update_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.
update_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.
