Implementation Reference
- src/server.ts:146-190 (handler)Handler function for the 'updateNote' MCP tool that validates input, calls the notes store update method, handles note not found and errors, and returns a standardized JSON text response.async ({ noteId, title, content }) => { try { const updatedNote = notesStore.updateNote(noteId, { title, content }); if (!updatedNote) { return { content: [ { type: "text", text: JSON.stringify({ success: false, error: "Note not found", noteId }, null, 2) } ] }; } return { content: [ { type: "text", text: JSON.stringify({ success: true, note: updatedNote }, null, 2) } ] }; } catch (err) { return { content: [ { type: "text", text: JSON.stringify({ success: false, error: "Failed to update note", noteId }, null, 2) } ] }; } },
- src/server.ts:141-145 (schema)Zod input schema for the 'updateNote' tool defining required noteId and optional title/content parameters.{ noteId: z.string().describe("The ID of the note to update"), title: z.string().optional().describe("The updated title of the note"), content: z.string().optional().describe("The updated content of the note") },
- src/notes-store.ts:51-67 (helper)Core helper method in NotesStore class that performs the actual note update logic by mutating the in-memory note object if it exists.updateNote(id: string, updates: { title?: string; content?: string }): Note | undefined { const note = this.notes[id]; if (!note) { return undefined; } if (updates.title !== undefined) { note.title = updates.title; } if (updates.content !== undefined) { note.content = updates.content; } return note; }
- src/notes-store.ts:2-7 (schema)TypeScript interface defining the structure of a Note object, used in the updateNote method and responses.export interface Note { id: string; title: string; content: string; createdAt: string; }
- src/server.ts:139-191 (registration)MCP server.tool registration for the 'updateNote' tool, specifying name, input schema, and inline handler function.server.tool( "updateNote", { noteId: z.string().describe("The ID of the note to update"), title: z.string().optional().describe("The updated title of the note"), content: z.string().optional().describe("The updated content of the note") }, async ({ noteId, title, content }) => { try { const updatedNote = notesStore.updateNote(noteId, { title, content }); if (!updatedNote) { return { content: [ { type: "text", text: JSON.stringify({ success: false, error: "Note not found", noteId }, null, 2) } ] }; } return { content: [ { type: "text", text: JSON.stringify({ success: true, note: updatedNote }, null, 2) } ] }; } catch (err) { return { content: [ { type: "text", text: JSON.stringify({ success: false, error: "Failed to update note", noteId }, null, 2) } ] }; } }, );
