WHAT IT DOES

What add_sprint_note does on Meridian

AI agents use add_sprint_note 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	Yes
`title`	string	Yes
`note_kind`	string	—	'note' (default) or 'thinking' for a thinking_sync scratchpad note.
`session_id`	string	Yes

Parameters from the server's own tool schema.

RISK

Why add_sprint_note is rated Medium

This tool creates ephemeral notes in a scratch pad for the current session only. The data is automatically deleted when the session ends, making it reversible and non-persistent. It supports coordination and debugging within a session but does not modify permanent data structures, execute commands, or cause irreversible changes.

From the tool's definition Tool description explicitly states 'Add an ephemeral note' and 'notes are auto-deleted when the session closes', indicating creation of temporary data structures that are reversible and session-scoped.

RECOMMENDED RULE

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

add_sprint_note Rate-limited

add_sprint_note 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_sprint_note

What does the add_sprint_note tool do? +

[SUPPORT] Add an ephemeral note to the current session's scratch pad. Use for constraints, blockers, working assumptions valid only this session. Notes are auto-deleted when the session closes. Pass note_kind='thinking' for a thinking_sync (HOOKS_DEBUG_STATE) note: a structured snapshot of the reasoning state (what was tried, what failed, current confirmed state) that the dashboard renders with a distinct icon. Intended for Claude's client-side thinking_sync post-tool-call hook, which extracts the extended-thinking scratchpad and persists it here so debugging state survives across turns and into the next session brief. 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_sprint_note accept? +

add_sprint_note accepts 4 parameters: body, title, note_kind, session_id. Required: body, title, session_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on add_sprint_note? +

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

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

Can I rate-limit add_sprint_note? +

Yes. Add a rate_limit block to the add_sprint_note 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_sprint_note completely? +

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

add_sprint_note 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.
