WHAT IT DOES

What promote_proposal does on Meridian

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

Parameter	Type	Required	Description
`project_id`	string	—	Project to create the sprint item under.
`proposal_id`	string	Yes
`project_name`	string	—	Project name — alternative to project_id; resolved to the id internally.
`sprint_item_title`	string	—	Override title for the sprint item; defaults to the proposal title.
`sprint_item_version`	string	—	Sprint version for the new item; defaults to 'current'.

Parameters from the server's own tool schema.

RISK

Why promote_proposal is rated Medium

This tool performs data creation (new sprint item) and modification (proposal status change, promoted_to_sprint_item_id field assignment). These are write operations with side effects, but they are reversible—the promotion could be undone by deleting the sprint item and resetting the proposal state. The tool does not delete data irreversibly, execute arbitrary code, or move money.

From the tool's definition The tool 'promote_proposal' creates a new sprint item and modifies the proposal's status from 'raw' or 'investigating' to 'promoted', establishing a persistent link between them. This is a reversible state change that creates and modifies data records.

RECOMMENDED RULE

The rule that runs promote_proposal safely

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

promote_proposal Rate-limited

promote_proposal 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 promote_proposal

What does the promote_proposal tool do? +

Promote a workspace proposal into a real sprint item, creating the link between them. The proposal must be in 'raw' or 'investigating' state. Creates a sprint item under the given project and sets the proposal's status to 'promoted' with promoted_to_sprint_item_id pointing to the new item. Returns {proposal, sprint_item_id, sprint_item_title, project_id}. Persistent-state disclosure: on hosted Meridian, supplied text and project/session metadata are sent to and stored in Meridian's service; self-hosted deployments keep them in the configured local SQLite/Postgres database. This data is visible in the dashboard/API and later project context or handoffs. Delete individual tasks, notes, or decisions where supported, or delete the project/account using the documented controls. Do not include secrets. It is categorised as a Write tool in the Meridian MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does promote_proposal accept? +

promote_proposal accepts 5 parameters: project_id, proposal_id, project_name, sprint_item_title, sprint_item_version. Required: proposal_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on promote_proposal? +

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

What risk level is promote_proposal? +

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

Can I rate-limit promote_proposal? +

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

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

promote_proposal is provided by the Meridian MCP server (@meridianmcp/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
