Update an existing project
AI agents use todoist_update_project to create or update resources in Enhanced Todoist MCP Server Extended — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced Todoist MCP Server Extended environment.
This tool modifies existing project data (name, description, color, etc.) but does not delete or destroy the project. The changes are reversible through subsequent update operations. The impact is limited to a single user's task management system without financial or irreversible consequences.
From the tool's definition Tool name is 'todoist_update_project' and description states 'Update an existing project' - a modification operation that creates or alters data reversibly.

PolicyLayer is an MCP gateway — it sits between your AI agents and Enhanced Todoist MCP Server Extended, and nothing reaches the server without passing your rules. This is the rule we recommend for todoist_update_project:
{
"version": "1",
"default": "deny",
"tools": {
"todoist_update_project": {
"limits": [
{
"counter": "todoist_update_project_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} todoist_update_project 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.
