WHAT IT DOES

What update_presentation does on Sanka MCP Server

AI agents use update_presentation to create or update resources in Sanka MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sanka MCP Server environment.

RISK

Why update_presentation is rated Medium

An AI agent can call update_presentation faster than any human can review: one bad instruction and it creates or modifies resources in Sanka MCP Server by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_presentation 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 update_presentation, this is the rule to start with:

update_presentation Rate-limited

update_presentation stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about update_presentation

What does the update_presentation tool do? +

Edit a presentation at the revision you last read: pass ops for targeted edits (preferred) or deck to replace the whole deck, and optionally a new title. Send slides back with their positioning and frames, and switch a slide to free placement (set_slide_positioning) only when the user asks for exact placement. On PRESENTATION_REVISION_CONFLICT nothing changed: call get_presentation and re-apply only your intended change with the new revision. Do not delete slides you did not create unless the user asks, and preview the changed slides again. Needs expected_workspace_id from current_workspace. It is categorised as a Write tool in the Sanka MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on update_presentation? +

Register the Sanka MCP Server MCP server in PolicyLayer and add a rule for update_presentation: 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.

What risk level is update_presentation? +

update_presentation is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit update_presentation? +

Yes. Add a rate_limit block to the update_presentation 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.

How do I block update_presentation completely? +

Set action: deny in the PolicyLayer policy for update_presentation. 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.

What MCP server provides update_presentation? +

update_presentation 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.
