WHAT IT DOES

What brc_update_allocations does on Red by Big Red Cloud

AI agents use brc_update_allocations to create or update resources in Red by Big Red Cloud, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Red by Big Red Cloud environment.

Parameter	Type	Required	Description
`bookTranId`	integer	Yes	Book transaction id to allocate from, for example 1001.
`routeToken`	string	Yes	Opaque routeToken from brc_route_request for this action workflow. Required for transactional tools. Routing permission only — does not replace preview-before-p
`companyName`	string	Yes	Company context name, for example YOUR-COMPANY-NAME.
`confirmWrite`	boolean	—	Must be true only after the user explicitly confirms posting the allocation update.
`connectionRef`	string	—	Opaque Red connection reference returned by brc_confirm_company_connection. Pass this exact value on every later tool call when the MCP client rotates session i
`allocationResolvers`	array	Yes	Allocations to create or update.

Parameters from the server's own tool schema.

RISK

Why brc_update_allocations is rated Medium

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

RECOMMENDED RULE

The rule that runs brc_update_allocations safely

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

brc_update_allocations Rate-limited

brc_update_allocations 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 brc_update_allocations

What does the brc_update_allocations tool do? +

Creates or updates allocations for a sender book transaction. Use brc_list_allocation_resolvers first to identify eligible receiver transactions. Do not call with confirmWrite=true until the user has reviewed the allocation preview and explicitly confirmed posting. Required fields: bookTranId and allocationResolvers with allocated amounts and receiver book transaction ids. Requires routeToken from brc_route_request for the matching action workflow. Call brc_route_request first with the user's complete original action request. Retain the returned routeToken through lookup, preview, and confirmation, and pass the same token on the final permitted transactional tool call. Never invent a placeholder token. A routeToken is not permission to post — preview-before-posting and confirmWrite/confirmDelete still apply. It is categorised as a Write tool in the Red by Big Red Cloud MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does brc_update_allocations accept? +

brc_update_allocations accepts 6 parameters: bookTranId, routeToken, companyName, confirmWrite, connectionRef, allocationResolvers. Required: bookTranId, routeToken, companyName, allocationResolvers. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on brc_update_allocations? +

Register the Red by Big Red Cloud MCP server in PolicyLayer and add a rule for brc_update_allocations: 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 Red by Big Red Cloud. Nothing to install.

What risk level is brc_update_allocations? +

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

Can I rate-limit brc_update_allocations? +

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

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

brc_update_allocations is provided by the Red by Big Red Cloud MCP server (https://red.bigredcloud.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
