What start_migration_plan does on Sanka MCP Server
AI agents invoke start_migration_plan to trigger actions in Sanka MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why start_migration_plan is rated High
start_migration_plan triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
The rule that runs start_migration_plan safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sanka MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For start_migration_plan, this is the rule to start with:
start_migration_plan stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Sanka MCP Server, apply this rule, and every start_migration_plan call is checked against it from then on.
Questions about start_migration_plan
Queue source inventory inspection and dry-run planning for an existing data migration. This changes migration planning state and may consume the workspace planning quota, but does not write destination records, approve or apply a plan. The response may be queued rather than complete: poll get_migration and then read get_migration_plan with the same workspace_id and migration_id. Reuse existing plans by default; set force=true only when a fresh scan and re-plan is explicitly requested. A blocked plan is still reviewable; inspect its destination identity and quarantine warnings, resolve the reported configuration or mapping issue, and re-plan to recheck safety before apply. After a timeout or service error, inspect get_migration before submitting again. API state guards reject planning after transfer has begun. It is categorised as a Execute tool in the Sanka MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Sanka MCP Server MCP server in PolicyLayer and add a rule for start_migration_plan: 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 Sanka MCP Server. Nothing to install.
start_migration_plan is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the start_migration_plan 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 start_migration_plan. 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.
start_migration_plan is provided by the Sanka MCP Server MCP server (sankahq/sanka-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
