Manage team members and permissions
AI agents use manage_team to create or update resources in Tally MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tally MCP environment.
Managing team members and permissions is a Write operation—it creates, modifies, or removes user access and roles, which are reversible changes to system state. While permissions changes can have broad impact (medium severity), they are not irreversible deletions (would be Destructive) or financial transactions.
From the tool's definition Tool name 'manage_team' and description 'Manage team members and permissions' indicate creation, modification, or deletion of team access control settings.
Documented attack patterns abuse exactly the kind of access manage_team gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Tally MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for manage_team:
{
"version": "1",
"default": "deny",
"tools": {
"manage_team": {
"limits": [
{
"counter": "manage_team_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}manage_team 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.

Manage team members and permissions. It is categorised as a Write tool in the Tally MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Tally MCP server in PolicyLayer and add a rule for manage_team: 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 Tally MCP. Nothing to install.
manage_team 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 manage_team 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 manage_team. 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.
manage_team is provided by the Tally MCP server (learnwithcc/tally-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Tally MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
