# add_note [SUPPORT] Add a per-project wiki note (setup, gotcha, howto, env, ...). Free-form title/body; comma-separated tags optional. Optional kind (wiki=gotcha/rule/howto, insight=strategic/product analysis, reference=external/one-off docs, code=warning/context anchored to a file, document=ingested report/spec/thesis) controls how the dashboard renders it. For a code anchor pass kind='code' plus file_path (and optional symbol): the note is then surfaced automatically when a session calls claim_file/get_file_claims for that path, so the executor sees the warning before editing. Pass source (a URL or file path) to record where the note came from — set automatically by ingest_document. Tag a note 'roadmap' AND pass a committable category (TECHNICAL/ARCHITECTURAL/PRODUCT) to also append it to ROADMAP.md's roadmap-notes anchor. 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.

HTML page: https://policylayer.com/tools/io-github-ajc3xc-meridian/add-note ## Facts - Tool: `add_note` - Server: Meridian (`@meridianmcp/mcp`) — https://policylayer.com/tools/io-github-ajc3xc-meridian.md - Install: `npx -y @meridianmcp/mcp` - Homepage: https://github.com/meridianmcp/Meridian - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: no - Parameters: 11 (2 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `body` | string | yes | | | `kind` | string | no | | | `tags` | string | no | | | `title` | string | yes | | | `source` | string | no | Provenance: a URL or file path this note was ingested from. Stored on the note (used by kind='document'). | | `symbol` | string | no | Optional symbol (class/function/method) to scope the code anchor to. File-level anchors (no symbol) surface for any symbol in the file. | | `category` | string | no | | | `priority` | string | no | high-priority notes surface first in generate_handoff and planner context. | | `file_path` | string | no | Code anchor (kind='code'): repo-relative or absolute path this note warns about. Surfaced at claim_file/get_file_claims for the same path. | | `project_id` | string | no | | | `project_name` | string | no | 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. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "add_note", "arguments": { "body": "", "title": "" } } } ``` ## Why add_note is rated Medium This tool creates and stores new wiki/reference documentation in a persistent system. It is reversible (notes can be edited or deleted later), has no side effects beyond data creation, does not execute code or commands, and does not delete or move money. It fits the Write category—a Create operation that modifies the project's knowledge base. From the tool's own definition: "Tool description states 'Add a per-project wiki note' with 'Free-form title/body' and optional parameters for organization. The action is creating and storing structured information persistently ('add_note' operation)." Risk signals: Accepts file system path (file_path) · Accepts raw HTML/template content (body) · High parameter count (11 properties) ## Use case AI agents use add_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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
