Part of the Meetsync MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use updateParticipant to create or modify resources in Meetsync. 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 updateParticipant 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 Meetsync.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Use this tool when you need to change a participant's name, email, timezone, or calendar provider, or when you want to soft-deactivate a participant by setting status to "inactive". Only the fields you supply are changed (partial update — other fields stay as-is). Prefer this over deleteParticipant when you want to stop scheduling someone without erasing their history.. It is categorised as a Write tool in the Meetsync 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 updateParticipant. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Meetsync MCP server.
updateParticipant 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 updateParticipant 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 updateParticipant. 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.
updateParticipant is provided by the Meetsync MCP server (nicholasemccormick/meetsync-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
