Implementation Reference
- index.ts:510-564 (handler)The handler function for the 'search_text' tool. Validates input using isValidSearchTextArgs, connects to MongoDB, queries the 'strings' collection for matching text using regex (case-insensitive), formats results with memory addresses and text, and returns them as tool content.case 'search_text': if (!isValidSearchTextArgs(request.params.arguments)) { throw new McpError( ErrorCode.InvalidParams, 'Invalid search text arguments' ); } try { const { text, caseSensitive, startAddress, endAddress } = request.params.arguments; /*const result = await ida.searchForText(text, { caseSensitive, startAddress, endAddress });*/ await client.connect(); db = client.db(dbName); collection = db.collection("strings"); let searchFor = "lua"; let newRegex = new RegExp(text, "i"); collection = db.collection("strings"); let res = await collection.find({ "TEXT": newRegex }) let result = await res.toArray() let result_count = result.length; let result_str = ""; for (let i = 0; i < result.length; i++) { result_str += ` ${result[i].MEMORY_ADDR} ${result[i].TEXT} \n` } return { content: [ { type: 'text', text: `Found ${result_count} \n\n ${result_str}`, }, ], } } catch (error: any) { return { content: [ { type: 'text', text: `Error searching for text: ${error.message || error}`, }, ], isError: true, }; } break;
- index.ts:42-47 (schema)TypeScript interface defining the input arguments for the search_text tool.interface SearchTextArgs { text: string; caseSensitive?: boolean; startAddress?: string | number; endAddress?: string | number; }
- index.ts:262-287 (registration)Tool registration in the ListTools handler, including name, description, and input schema matching SearchTextArgs.{ name: 'search_text', description: 'Search for text in the binary', inputSchema: { type: 'object', properties: { text: { type: 'string', description: 'Text to search for', }, caseSensitive: { type: 'boolean', description: 'Whether the search is case sensitive (default: false)', }, startAddress: { type: 'string', description: 'Start address for search (optional)', }, endAddress: { type: 'string', description: 'End address for search (optional)', }, }, required: ['text'], }, },
- index.ts:105-111 (helper)Validation function to check if arguments conform to SearchTextArgs interface, used in the handler.const isValidSearchTextArgs = (args: any): args is SearchTextArgs => { return ( typeof args === 'object' && args !== null && typeof args.text === 'string' ); };
