AI agents use update_epic to create or update resources in Taiga MCP Bridge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Taiga MCP Bridge environment.
update_epic modifies existing epic data in a project management system reversibly. This is a Write operation—data is changed but not destroyed and can be reverted. Severity is medium because misuse could corrupt project planning data or assign work incorrectly, but the blast radius is limited to a single project management system and changes are auditable and reversible.
From the tool's definition Tool name 'update_epic' combined with server context showing it 'enables AI tools to create and manage projects, epics, user stories, tasks, issues, and sprints.' The sibling tools include create_epic and other modification operations (assign_*,…
Documented attack patterns abuse exactly the kind of access update_epic gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Taiga MCP Bridge, and nothing reaches the server without passing your rules. This is the rule we recommend for update_epic:
{
"version": "1",
"default": "deny",
"tools": {
"update_epic": {
"limits": [
{
"counter": "update_epic_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_epic 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.

update_epic. It is categorised as a Write tool in the Taiga MCP Bridge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Taiga MCP Bridge MCP server in PolicyLayer and add a rule for update_epic: 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 Taiga MCP Bridge. Nothing to install.
update_epic 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 update_epic 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 update_epic. 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.
update_epic is provided by the Taiga MCP Bridge MCP server (talhaorak/pytaiga-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
