WHAT IT DOES

What plan_attachment_message does on GuildControl MCP

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

RISK

Why plan_attachment_message is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs plan_attachment_message safely

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

plan_attachment_message Rate-limited

plan_attachment_message 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.

FAQ

Questions about plan_attachment_message

What does the plan_attachment_message tool do? +

Prepare a process-bound keyed plan for sending one local regular file to one exact allowlisted Discord channel. Reads at most the configured byte ceiling, rejects links and path escapes, binds a keyed digest to the stable bytes, and verifies exact channel, reply, notification, and complete bot permission evidence without writing or persisting file or message content. It is categorised as a Write tool in the GuildControl MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on plan_attachment_message? +

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

What risk level is plan_attachment_message? +

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

Can I rate-limit plan_attachment_message? +

Yes. Add a rate_limit block to the plan_attachment_message 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 plan_attachment_message completely? +

Set action: deny in the PolicyLayer policy for plan_attachment_message. 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 plan_attachment_message? +

plan_attachment_message is provided by the GuildControl MCP server (guildctl). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
