Add a new context entry or overwrite an existing one by key. Context entries are synced to all connected AI tools so they persist across sessions.
AI agents use context_sync_update to create or update resources in Scan Your Ai Toolkit — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Scan Your Ai Toolkit environment.
The tool modifies context entries that persist across AI tool sessions. Although it doesn't delete or execute code, it creates or overwrites data that affects all connected AI tools, making it Write category. Severity is high because overwriting context entries could affect multiple AI agents' behavior and decisions, with potential for misuse to inject malicious instructions or data across an AI toolkit.
From the tool's definition Tool description states 'Add a new context entry or overwrite an existing one' and 'synced to all connected AI tools so they persist across sessions.' This directly creates or modifies data.
Attacks that exploit this kind of access
Add a new context entry or overwrite an existing one by key. Context entries are synced to all connected AI tools so they persist across sessions. It is categorised as a Write tool in the Scan Your Ai Toolkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Scan Your Ai Toolkit MCP server in PolicyLayer and add a rule for context_sync_update: 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 Scan Your Ai Toolkit. Nothing to install.
context_sync_update 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 context_sync_update 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 context_sync_update. 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.
context_sync_update is provided by the Scan Your Ai Toolkit MCP server (sakthivelchan89/scan_your_ai_toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
context_sync_update is one line of Scan Your Ai Toolkit's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
