Creates a new release or updates an existing release in Plan. If releaseDbid is provided, updates the release; otherwise creates a new one. If projectID is provided, automatically adds the release to the project (atomic operation).
AI agents use create_or_update_release to create or update resources in MCP DevOps Plan Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP DevOps Plan Server environment.
This tool performs create and update operations on releases within a DevOps Plan system. These are Write operations as they create new data or modify existing data in a reversible manner (releases can be updated again or deleted). It is not Destructive because updates and creation are not irreversible.
From the tool's definition Tool description states it 'Creates a new release or updates an existing release in Plan.' The verb 'creates' and 'updates' clearly indicate write operations that modify data reversibly.
Attacks that exploit this kind of access
Creates a new release or updates an existing release in Plan. If releaseDbid is provided, updates the release; otherwise creates a new one. If projectID is provided, automatically adds the release to the project (atomic operation). It is categorised as a Write tool in the MCP DevOps Plan Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP DevOps Plan Server MCP server in PolicyLayer and add a rule for create_or_update_release: 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 MCP DevOps Plan Server. Nothing to install.
create_or_update_release 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 create_or_update_release 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 create_or_update_release. 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.
create_or_update_release is provided by the MCP DevOps Plan Server MCP server (mrchris2000/mcp-devops-plan). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
