WHAT IT DOES

What add_project_member does on A3plus

Parameter	Type	Required	Description
`email`	string	Yes	Email of the existing A3Plus account to add as an editor.
`projectId`	string	Yes	The A3Plus project ID.

Parameters from the server's own tool schema.

RISK

Why add_project_member is rated Medium

An AI agent can call add_project_member faster than any human can review: one bad instruction and it creates or modifies resources in A3plus by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs add_project_member safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A3plus, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_project_member, this is the rule to start with:

add_project_member Rate-limited

add_project_member 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.

The button opens the PolicyLayer dashboard: create your workspace, connect A3plus, apply this rule, and every add_project_member call is checked against it from then on.

FAQ

Questions about add_project_member

What does the add_project_member tool do? +

Add an existing A3Plus account as a project editor, BY EMAIL (idempotent — re-adding is a no-op). The email must already have an A3Plus account; inviting unregistered emails is out of scope (ask them to register first). It is categorised as a Write tool in the A3plus MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does add_project_member accept? +

add_project_member accepts 2 parameters: email, projectId. Required: email, projectId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on add_project_member? +

Register the A3plus MCP server in PolicyLayer and add a rule for add_project_member: 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 A3plus. Nothing to install.

What risk level is add_project_member? +

add_project_member is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_project_member? +

Yes. Add a rate_limit block to the add_project_member 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.

How do I block add_project_member completely? +

Set action: deny in the PolicyLayer policy for add_project_member. 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.

What MCP server provides add_project_member? +

add_project_member is provided by the A3plus MCP server (a3plus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
