WHAT IT DOES

What updatePlanPhase does on Stable Baseline

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

Parameter	Type	Required	Description
`name`	string	—
`color`	string \| null	—	Phase color. Must be one of: #3b82f6 (Blue), #f59e0b (Amber), #8b5cf6 (Purple), #ec4899 (Pink), #06b6d4 (Cyan), #14b8a6 (Teal), #6366f1 (Indigo), #6b7280 (Gray)
`status`	string	—	Status: not_started, in_progress, completed, on_hold, cancelled.
`phaseId`	string	Yes
`end_date`	string	—
`position`	number	—
`priority`	string	—	Priority: low, medium, high, critical.
`wbs_code`	string	—
`start_date`	string	—
`description`	string	—
`versionTimestamp`	number	Yes	Version timestamp from getPlanPhase() for optimistic locking.

Parameters from the server's own tool schema.

RISK

Why updatePlanPhase is rated Medium

This tool modifies an existing plan phase, which is a reversible operation. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read). The requirement for versionTimestamp suggests it tracks changes and enables rollback, supporting the Write classification.

From the tool's definition Tool name 'updatePlanPhase' directly indicates modification of data. Description states 'Update a plan phase', confirming reversible modification of existing plan entities.

RECOMMENDED RULE

The rule that runs updatePlanPhase safely

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

updatePlanPhase Rate-limited

updatePlanPhase 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 updatePlanPhase

What does the updatePlanPhase tool do? +

Update a plan phase. Requires versionTimestamp from getPlanPhase (not getPlan). It is categorised as a Write tool in the Stable Baseline MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does updatePlanPhase accept? +

updatePlanPhase accepts 11 parameters: name, color, status, phaseId, end_date, position, priority, wbs_code, start_date, description, versionTimestamp. Required: phaseId, versionTimestamp. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on updatePlanPhase? +

Register the Stable Baseline MCP server in PolicyLayer and add a rule for updatePlanPhase: 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 Stable Baseline. Nothing to install.

What risk level is updatePlanPhase? +

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

Can I rate-limit updatePlanPhase? +

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

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

updatePlanPhase is provided by the Stable Baseline MCP server (https://api.stablebaseline.io/functions/v1/cloud-serve/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
