WHAT IT DOES

What create_project does on Meridian

AI agents use create_project 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
`name`	string	Yes
`execution_mode`	string	—	Executor posture for sessions on this project. 'autonomous' (default) claims and runs sprint items immediately without asking; 'interactive' asks for direction
`parent_project_id`	string	—	Optional parent project id — makes this a subproject that inherits the parent's north_star when it has none of its own. Subprojects are one level deep: the pare

Parameters from the server's own tool schema.

RISK

Why create_project is rated Medium

This tool creates new projects and persists metadata in a database (SQLite/Postgres). While the action is reversible (the description mentions 'delete the project' as a documented control), it is fundamentally a Write operation—it creates and modifies persistent state.

From the tool's definition Tool description explicitly states 'Create a new Meridian project' and 'text and project/session metadata are sent to and stored in Meridian's service'. This is data creation and persistent modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_project 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 create_project, this is the rule to start with:

create_project Rate-limited

create_project 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 create_project

What does the create_project tool do? +

[MAINTENANCE] Create a new Meridian project. 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 create_project accept? +

create_project accepts 3 parameters: name, execution_mode, parent_project_id. Required: name. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on create_project? +

Register the Meridian MCP server in PolicyLayer and add a rule for create_project: 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 create_project? +

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

Can I rate-limit create_project? +

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

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

create_project 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.
