Implementation Reference

• src/tools/search.ts:144-155 (handler)

  Handler function for the m9k_full tool which retrieves full chunk content from the database based on provided IDs.

    async ({ chunkIds }) => {
      const placeholders = chunkIds.map(() => '?').join(',');
      const stmt = ctx.db.prepare(
        `SELECT id, session_id, idx, kind, user_content, assistant_content, hash, timestamp, token_count, tags, metadata_json
         FROM conv_chunks WHERE id IN (${placeholders}) AND deleted_at IS NULL`,
      );
      const rows = stmt.all(...chunkIds);
      return {
        content: [{ type: 'text' as const, text: JSON.stringify(rows) }],
      };
    },
  );

• src/tools/search.ts:134-136 (schema)

  Zod input schema definition for the m9k_full tool, validating an array of chunk IDs.

  inputSchema: {
    chunkIds: z.array(z.string()).min(1).max(20).describe('Chunk IDs to retrieve in full'),
  },

• src/tools/search.ts:129-143 (registration)

  Registration block for the m9k_full tool using the MCP server instance.

  server.registerTool(
    'm9k_full',
    {
      description:
        'Retrieve full content of chunks by IDs. Use after m9k_search to get complete context.',
      inputSchema: {
        chunkIds: z.array(z.string()).min(1).max(20).describe('Chunk IDs to retrieve in full'),
      },
      annotations: {
        readOnlyHint: true,
        destructiveHint: false,
        idempotentHint: true,
        openWorldHint: false,
      },
