MCP Memory Server

Instructions

Implementation Reference

• src/index.ts:868-887 (handler)

  MCP tool handler that processes the tool call, enriches with current session context, and delegates to ChangelogManager.addChangelogEntry
  case 'add_changelog_entry': { const currentMemory = await this.memoryManager.getProjectMemory(); const description = args.description as string; const filesChanged = args.filesChanged as string[]; const type = args.type as 'added' | 'changed' | 'deprecated' | 'removed' | 'fixed' | 'security'; const breakingChange = (args.breakingChange as boolean) || false; const impact = (args.impact as 'major' | 'minor' | 'patch') || 'minor'; await this.changelogManager.addChangelogEntry({ sessionId: currentMemory.currentSession.sessionId, task: currentMemory.currentSession.task, type, description, filesChanged, breakingChange, approvals: {}, impact }); return { content: [{ type: 'text', text: 'Changelog entry added successfully' }] }; }
• src/index.ts:690-700 (schema)

  Input JSON schema for the add_changelog_entry tool defining parameters and validation rules
  inputSchema: { type: 'object', properties: { description: { type: 'string', description: 'Description of the change' }, filesChanged: { type: 'array', items: { type: 'string' }, description: 'Files that were changed' }, type: { type: 'string', enum: ['added', 'changed', 'deprecated', 'removed', 'fixed', 'security'] }, breakingChange: { type: 'boolean', description: 'Whether this is a breaking change' }, impact: { type: 'string', enum: ['major', 'minor', 'patch'] } }, required: ['description', 'filesChanged', 'type'] }
• src/index.ts:688-701 (registration)

  Tool registration in MCP server's tools list, including name, description, and schema
  name: 'add_changelog_entry', description: 'Add an entry to the project changelog', inputSchema: { type: 'object', properties: { description: { type: 'string', description: 'Description of the change' }, filesChanged: { type: 'array', items: { type: 'string' }, description: 'Files that were changed' }, type: { type: 'string', enum: ['added', 'changed', 'deprecated', 'removed', 'fixed', 'security'] }, breakingChange: { type: 'boolean', description: 'Whether this is a breaking change' }, impact: { type: 'string', enum: ['major', 'minor', 'patch'] } }, required: ['description', 'filesChanged', 'type'] } },
• src/changelog-manager.ts:50-68 (helper)

  Core helper method in ChangelogManager that persists the changelog entry to JSON file and regenerates Markdown changelog
  async addChangelogEntry(entry: Omit<ChangelogEntry, 'date'>): Promise<void> { try { const changelog = await this.getChangelog(); const newEntry: ChangelogEntry = { ...entry, date: new Date().toISOString() }; changelog.unshift(newEntry); // Add to beginning await fs.writeJson(this.changelogPath, changelog, { spaces: 2 }); await this.updateMarkdownChangelog(changelog); console.log(chalk.green(`📝 Changelog entry added: ${entry.description}`)); } catch (error) { console.error(chalk.red('Error adding changelog entry:'), error); } }
