WHAT IT DOES

What update_deal does on Meta Council

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

`notes`	string	—
`stage`	string	—
`title`	string	—
`amount`	number	—
`company`	string	—
`deal_id`	string	Yes
`currency`	string	—	Exactly three ASCII letters, such as USD; saved uppercase. Omit to keep the current currency. Syntax only, not an ISO registry.

`expected_close_date`	string	—	ISO date YYYY-MM-DD.

Parameters from the server's own tool schema.

RISK

Why update_deal is rated Medium

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

RECOMMENDED RULE

The rule that runs update_deal safely

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

update_deal Rate-limited

update_deal 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 update_deal

What does the update_deal tool do? +

Update one of the caller's deals — most commonly to ADVANCE its stage (e.g. discovery -> proposal). Moving to closed_won/closed_lost stamps the close date; reopening to an open stage clears it. Only the fields you pass change; deal_id is required. It is categorised as a Write tool in the Meta Council MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does update_deal accept? +

update_deal accepts 9 parameters: notes, stage, title, amount, company, deal_id, currency, probability, expected_close_date. Required: deal_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on update_deal? +

Register the Meta Council MCP server in PolicyLayer and add a rule for update_deal: 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 Meta Council. Nothing to install.

What risk level is update_deal? +

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

Can I rate-limit update_deal? +

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

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

update_deal is provided by the Meta Council MCP server (https://meta-council.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
