MCP Knowledge Base Server

Instructions

Implementation Reference

• src/mcp-server.ts:60-72 (registration)

  Registration of the 'add_directory' MCP tool, including name, description, and input schema.

  {
    name: 'add_directory',
    description: '添加目录中的所有文档到知识库',
    inputSchema: {
      type: 'object',
      properties: {
        directory_path: {
          type: 'string',
          description: '目录路径'
        }
      },
      required: ['directory_path']
    }

• src/mcp-server.ts:63-71 (schema)

  JSON schema defining the input parameters for the add_directory tool (directory_path: string).

  inputSchema: {
    type: 'object',
    properties: {
      directory_path: {
        type: 'string',
        description: '目录路径'
      }
    },
    required: ['directory_path']

• src/mcp-server.ts:175-186 (handler)

  MCP server handler for 'add_directory' tool: parses arguments, delegates to KnowledgeBase.addDirectory, returns formatted success message with document count.

  case 'add_directory': {
    const { directory_path } = args as { directory_path: string };
    const count = await this.knowledgeBase.addDirectory(directory_path);
    return {
      content: [
        {
          type: 'text',
          text: `已从目录 "${directory_path}" 添加了 ${count} 个文档到知识库`
        }
      ]
    };
  }

• src/knowledge-base.ts:37-46 (handler)

  Core handler logic in KnowledgeBase class: processes all documents in directory using DocumentProcessor, stores them in memory map, persists index to disk, returns number of added documents.

  async addDirectory(dirPath: string): Promise<number> {
    const documents = await this.processor.processDirectory(dirPath);
    
    for (const doc of documents) {
      this.documents.set(doc.id, doc);
    }
    
    await this.saveIndex();
    return documents.length;
  }
