write · MCP Backlog Server MCP: Risk & Policy

WHAT IT DOES

What write does on MCP Backlog Server

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

WHY IT NEEDS A POLICY

Why write needs a policy

The tool provides reversible creation and modification of backlog items stored as markdown files with automatic versioning. While it includes 'list' (a Read operation), the primary purpose is Write—creating and amending work items. The automatic versioning mitigates data loss risk, and changes can be rolled back via version history, so this does not reach Destructive severity.

From the tool's definition Tool name 'write' with description stating 'Write access to backlog management - create, amend, and list backlog work items'. The description explicitly mentions 'create' and 'amend' (modify) operations.

Verdict

write Rate-limited

write 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.
