WHAT IT DOES

What add_insight does on Meridian

AI agents use add_insight 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
`body`	string	—	The insight (markdown).
`tags`	array	—	Optional tags.
`title`	string	Yes
`horizon`	string	—	Shelf-life. 'permanent' always appears in the planning brief. Default 'quarter'.
`project_id`	string	—
`project_name`	string	—	Project name — an alternative to project_id; resolved to the id internally. project_id wins if both are given.

Parameters from the server's own tool schema.

RISK

Why add_insight is rated Medium

The tool creates and persists new knowledge artifacts (insights) in a database. While non-destructive and reversible (typical writes), it modifies system state by adding records that influence future planning decisions. The 'medium' severity reflects that stored insights shape decision-making but don't directly execute external operations, move money, or delete data.

From the tool's definition Tool description states it records and stores information: 'Record a durable STRATEGIC INSIGHT', 'Returns the stored insight', and 'supplied text and project/session metadata are sent to and stored in Meridian's service'. This is data creation/modification.

RECOMMENDED RULE

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

add_insight Rate-limited

add_insight 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 add_insight

What does the add_insight tool do? +

[SUPPORT] Record a durable STRATEGIC INSIGHT — accumulated understanding that generates future decisions. A first-class knowledge type SEPARATE from decisions (choices with a lifecycle) and notes (reference). horizon sets its shelf-life: 'permanent' insights ALWAYS surface in get_planning_brief; 'year'/'quarter' are time-boxed. Returns the stored insight. 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 add_insight accept? +

add_insight accepts 6 parameters: body, tags, title, horizon, project_id, project_name. Required: title. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on add_insight? +

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

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

Can I rate-limit add_insight? +

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

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

add_insight 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.
